Currently `pallet-collator-selection` does not expose a way to query the
assigned pot account derived from the `PotId` configuration item.
Without it, it is not possible to transfer the existential deposit to
it.

This PR addresses this issue by exposing an extra constant.

## Description

The `frame-benchmarking-cli` crate has not been buildable without the
`rocksdb` feature since version 1.17.0.

**Error:**  
```rust
self.database()?.unwrap_or(Database::RocksDb),
                             ^^^^^^^ variant or associated item not found in `Database`
```

This issue is also related to the `rocksdb` feature bleeding (#3793),
where the `rocksdb` feature was always activated even when compiling
this crate with `--no-default-features`.

**Fix:**  
- Resolved the error by choosing `paritydb` as the default database when
compiled without the `rocksdb` feature.
- Fixed the issue where the `sc-cli` crate's `rocksdb` feature was
always active, even compiling `frame-benchmarking-cli` with
`--no-default-features`.

## Review Notes

Fix the crate to be built without rocksdb, not intended to solve #3793.

Saw this test flake a few times, last time
[here](https://github.com/paritytech/polkadot-sdk/actions/runs/12834432188/job/35791830215).

We first fetch all processes in the test, then query `/proc/<pid>/stat`
for every one of them. When the file was not found, we would error. Now
we tolerate not finding this file. Ran 200 times locally without error,
before would fail a few times, probably depending on process fluctuation
(which I expect to be high on CI runners).

Use docify export for parachain template hardcoded configuration and embed it in its README #6333 (#7093)

Use docify export for parachain template hardcoded configuration and
embed it in its README #6333

Docify currently has a limitation of not being able to embed a
variable/const in its code, without embedding it's definition, even if
do something in a string like

"this is a sample string ${sample_variable}"

It will embed the entire string 
"this is a sample string ${sample_variable}"
without replacing the value of sample_variable from the code

Hence, the goal was just to make it obvious in the README where the
PARACHAIN_ID value is coming from, so a note has been added at the start
for the same, so whenever somebody is running these commands, they will
be aware about the value and replace accordingly.

To make it simpler, we added a 
rust ignore block so the user can just look it up in the readme itself
and does not have to scan through the runtime directory for the value.

Follow-up to #6825, which introduced this bug.

We use the `can_build_upon` method to ask the runtime if it is fine to
build another block. The runtime checks this based on the
[`ConsensusHook`](https://github.com/paritytech/polkadot-sdk/blob/c1b7c302/cumulus/pallets/aura-ext/src/consensus_hook.rs#L110-L110)
implementation, the most popular one being the `FixedConsensusHook`.

In #6825 I removed a check that would always allow us to build when we
are building on an included block. Turns out this check is still
required when:
1. The [`UnincludedSegment`
](https://github.com/paritytech/polkadot-sdk/blob/c1b7c302

/cumulus/pallets/parachain-system/src/lib.rs#L758-L758)
storage item in pallet-parachain-system is equal or larger than the
unincluded segment.
2. We are calling the `can_build_upon` runtime API where the included
block has progressed offchain to the current parent block (so last entry
in the `UnincludedSegment` storage item).

In this scenario the last entry in `UnincludedSegment` does not have a
hash assigned yet (because it was not available in `on_finalize` of the
previous block). So the unincluded segment will be reported at its
maximum length which will forbid building another block.

Ideally we would have a more elegant solution than to rely on the
node-side here. But for now the check is reintroduced and a test is
added to not break it again by accident.

We already use it for lots of pallet.

Keeping it feature gated by experimental means we lose the information
of which pallet was using experimental before the migration to frame
crate usage.

We can consider `polkadot-sdk-frame` crate unstable but let's not use

Migrate staking currency from `traits::LockableCurrency` to
`traits::fungible::holds`.

Resolves part of https://github.com/paritytech/polkadot-sdk/issues/226.

## Changes
### Nomination Pool
TransferStake is now incompatible with fungible migration as old pools
were not meant to have additional ED. Since they are anyways deprecated,
removed its usage from all test runtimes.

### Staking
- Config: `Currency` becomes of type `Fungible` while `OldCurrency` is
the `LockableCurrency` used before.
- Lazy migration of accounts. Any ledger update will create a new hold
with no extra reads/writes. A permissionless extrinsic
`migrate_currency()` releases the old `lock` along with some
housekeeping.
- Staking now requires ED to be left free. It also adds no consumer to
staking accounts.
- If hold cannot be applied to all stake, the un-holdable part is force
withdrawn from the ledger.

### Delegated Staking
The pallet does not add provider for agents anymore.

## Migration stats
### Polkadot
Total accounts that can be migrated: 59564
Accounts failing to migrate: 0
Accounts with stake force withdrawn greater than ED: 59
Total force withdrawal: 29591.26 DOT

### Kusama
Total accounts that can be migrated: 26311
Accounts failing to migrate: 0
Accounts with stake force withdrawn greater than ED: 48
Total force withdrawal: 1036.05 KSM


[Full logs here](https://hackmd.io/@ak0n/BklDuFra0).

## Note about locks (freeze) vs holds
With locks or freezes, staking could use total balance of an account.
But with holds, the account needs to be left with at least Existential
Deposit in free balance. This would also affect nomination pools which
till now has been able to stake all funds contributed to it. An
alternate version of this PR is
https://github.com/paritytech/polkadot-sdk/pull/5658 where staking
pallet does not add any provider, but means pools and delegated-staking
pallet has to provide for these accounts and makes the end to end logic
(of provider and consumer ref) lot less intuitive and prone to bug.

This PR now introduces requirement for stakers to maintain ED in their
free balance. This helps with removing the bug prone incrementing and
decrementing of consumers and providers.

## TODO
- [x] Test: Vesting + governance locked funds can be staked.
- [ ] can `Call::restore_ledger` be removed? @gpestana 
- [x] Ensure unclaimed withdrawals is not affected by no provider for
pool accounts.
- [x] Investigate kusama accounts with balance between 0 and ED.
- [x] Permissionless call to release lock.
- [x] Migration of consumer (dec) and provider (inc) for direct stakers.
- [x] force unstake if hold cannot be applied to all stake.
- [x] Fix try state checks (it thinks nothing is staked for unmigrated
ledgers).
- [x] Bench `migrate_currency`.
- [x] Virtual Staker migration test.
- [x] Ensure total issuance is upto date when minting rewards.

Zombienet substrate tests PoC (using native provider).

cc: @emamihe @alvicsam

closes https://github.com/paritytech/polkadot-sdk/issues/6911

The changes from v0.10.3 are only related to dependencies version. This
should fix some failing CIs.

This PR also updates the Rust cache version in CI.

Closes #3149 

## Description

This PR introduces `pallet-asset-rewards`, which allows accounts to be
rewarded for freezing `fungible` tokens. The motivation for creating
this pallet is to allow incentivising LPs.

See the pallet docs for more info about the pallet.

## Runtime changes

The pallet has been added to
- `asset-hub-rococo`
- `asset-hub-westend`

The `NativeAndAssets` `fungibles` Union did not contain `PoolAssets`, so
it has been renamed `NativeAndNonPoolAssets`

A new `fungibles` Union `NativeAndAllAssets` was created to encompass
all assets and the native token.

## TODO
- [x] Emulation tests
- [x] Fill in Freeze logic (blocked
https://github.com/paritytech/polkadot-sdk/issues/3342) and re-run
benchmarks

This PR provides the partial results of the `GetRecord` kademlia query.

This significantly improves the authority discovery records, from ~37
minutes to ~2/3 minutes.
In contrast, libp2p discovers authority records in around ~10 minutes. 

The authority discovery was slow because litep2p provided the records
only after the Kademlia query was completed. A normal Kademlia query
completes in around 40 seconds to a few minutes.
In this PR, partial records are provided as soon as they are discovered
from the network.

### Testing Done

Started a node in Kusama with `--validator` and litep2p backend.
The node discovered 996/1000 authority records in ~ 1 minute 45 seconds.

Normally, approval-voting wouldn't receive duplicate assignments because
approval-distribution makes sure of it, however in the situation where
we restart we might receive the same assignment again and since
approval-voting already persisted it we will end up inserting it twice
in `ApprovalEntry.tranches.assignments` because that's an array.

Fix this by making sure duplicate assignments are a noop if the
validator already had an assignment imported at the same tranche.

## Changes
We now use relay chain slots to measure velocity on chain. Previously we
were storing the current parachain slot. Then in `on_state_proof` of the
`ConsensusHook` we were checking how many blocks were athored in the
current parachain slot. This works well when the parachain slot time and
relay chain slot time is the same. With elastic scaling, we can have
parachain slot times lower than that of the relay chain. In these cases
we want to measure velocity in relation to the relay chain. This PR
adjusts that.


##  Migration
This PR includes a migration. Storage item `SlotInfo` of pallet
`aura-ext` is renamed to `RelaySlotInfo` to better reflect its new
content. A migration has been added that just kills the old storage
item. `RelaySlotInfo` will be `None` initially but its value will be
adjusted after one new relay chain slot arrives.

The umbrella crate quick-check was always failing whenever there was
something misformated in the whole codebase.
This leads to an error that indicates that a new crate was added, even
when it was not.

After this PR we only apply `cargo fmt` to the newly generated umbrella
crate `polkadot-sdk`. This results in this check being independent from
the fmt job which should check the entire codebase.
