Hello
I found several spelling errors.
Br, Elias.

The polkadot.network website was recently refreshed and the
`favicon-32x32.png` was removed. It was linked in some docs and so the
docs have been updated to point to a working favicon on the new website.

Previously the lychee link checker was failing on all PRs.

Uses custom metadata to exclude chain-specific crates.  
The only concern is that devs who want to use chain-specific crates,
still need to select matching versions numbers. Could possibly be
addresses with chain-specific umbrella crates, but currently it should
be possible to use [psvm](https://github.com/paritytech/psvm).

An attempt to improve [the
docs](https://paritytech.github.io/polkadot-sdk/master/polkadot_sdk_docs/index.html)
by applying various corrections:

- grammar/stylistics,
- formatting,
- broken links,
- broken markdown table,
- outdated vscode setting name,
- typos,
- consistency,
- etc.

Part of https://github.com/paritytech/eng-automation/issues/10

The word is duplicated in the document and use this commit to remove
them.

Resolves https://github.com/paritytech/polkadot-sdk/issues/4468

Gives instructions on how to enable elastic scaling MVP to parachain
teams.

Still a draft because it depends on further changes we make to the
slot-based collator:
https://github.com/paritytech/polkadot-sdk/pull/4097

Parachains cannot use this yet because the collator was not released and
no relay chain network has been configured for elastic scaling yet

This should remove nearly all usage of `sp-std` except:
- bridge and bridge-hubs
- a few of frames re-export `sp-std`, keep them for now
- there is a usage of `sp_std::Writer`, I don't have an idea how to move
it

Please review proc-macro carefully. I'm not sure I'm doing it the right
way.

Note: need `/bot fmt`

After preparing in https://github.com/paritytech/polkadot-sdk/pull/4633,
we can lift also all internal dependencies up to the workspace.

This does not actually change anything, but uses `workspace = true` for
all dependencies. You can check it with:
```bash
git checkout -q $(git merge-base oty-lift-all-deps origin/master)
cargo tree -e features > master.out

git checkout -q oty-lift-all-deps
cargo tree -e features > new.out
diff master.out new.out
```

It did not yet lift 100% of dependencies, some inside of `target.*` or
some that had conflicting aliases introduced recently. But i will do
these together in a follow-up with CI checks.

Can be reproduced with [zepter](https://github.com/ggwpez/zepter/):
`zepter transpose d lift-to-workspace "regex:.*" --version-resolver
highest --skip-package "polkadot-sdk" --ignore-errors --fix`.

remove unnecessary words in comments.

After using this tutorial in PBA, there was a few areas to improve it.
Moreover, I have:

- Improve `your_first_pallet`, link it in README, improve the parent
`guide` section.
- Updated the templates page, in light of recent efforts related to in
https://github.com/paritytech/polkadot-sdk/issues/3155
- Added small ref docs about metadata, completed the one about native
runtime, added one about host functions.
- Remove a lot of unfinished stuff from sdk-docs
- update diagram for `Hooks`

Thanks for @xlc for the original seed info, I've just fixed it up a bit
and added example links.

I've moved the comparison between eth-rpc-api and frontier outside, as
it is opinionation. I think the content there was good but should live
in the README of the corresponding repos. No strong opinion, happy
either way.

Inherited workspace dependencies cannot be renamed by the crate using
them (see [1](https://github.com/rust-lang/cargo/issues/12546),
[2](https://stackoverflow.com/questions/76792343/can-inherited-dependencies-in-rust-be-aliased-in-the-cargo-toml-file)).
Since we want to use inherited workspace dependencies everywhere, we
first need to unify all aliases that we use for a dependency throughout
the workspace.
The umbrella crate is currently excluded from this procedure, since it
should be able to export the crates by their original name without much
hassle.

For example: one crate may alias `parity-scale-codec` to `codec`, while
another crate does not alias it at all. After this change, all crates
have to use `codec` as name. The problematic combinations were:
- conflicting aliases: most crates aliases as `A` but some use `B`.
- missing alias: most of the crates alias a dep but some dont.
- superfluous alias: most crates dont alias a dep but some do.

The script that i used first determines whether most crates opted to
alias a dependency or not. From that info it decides whether to use an
alias or not. If it decided to use an alias, the most common one is used
everywhere.

To reproduce, i used
[this](https://github.com/ggwpez/substrate-scripts/blob/master/uniform-crate-alias.py)
python script in combination with
[this](https://github.com/ggwpez/zepter/blob/38ad10585fe98a5a86c1d2369738bc763a77057b/renames.json)
error output from Zepter.

some minor text fixes.

Added reference doc about:
- the pallet genesis config and genesis build, 
- runtime `genesis-builder` API,
- presets,
- interacting with the `chain-spec-builder` tool

I've added [minimal
runtime](https://github.com/paritytech/polkadot-sdk/tree/mku-chain-spec-guide/docs/sdk/src/reference_docs/chain_spec_runtime)
to demonstrate above topics.

I also sneaked in some little improvement to `chain-spec-builder` which
allows to parse output of the `list-presets` command.

# Umbrella Crate

The Polkadot-SDK "umbrella" is a crate that re-exports all other
published crates. This makes it
possible to have a very small `Cargo.toml` file that only has one
dependency, the umbrella
crate. This helps with selecting the right combination of crate
versions, since otherwise 3rd
party tools are needed to select a compatible set of versions.

## Features

The umbrella crate supports no-std builds and can therefore be used in
the runtime and node.
There are two main features: `runtime` and `node`. The `runtime` feature
enables all `no-std`
crates, while the `node` feature enables all `std` crates. It should be
used like any other
crate in the repo, with `default-features = false`.

For more fine-grained control, additionally, each crate can be enabled
selectively. The umbrella
exposes one feature per dependency. For example, if you only want to use
the `frame-support`
crate, you can enable the `frame-support` feature.

The umbrella exposes a few more g...

The XCM docs were pretty much moved to the new rust docs format in
https://github.com/paritytech/polkadot-sdk/pull/2633, with the addition
of the XCM cookbook, which I plan to add more examples to shortly.

These docs were not mentioned in the polkadot-sdk rust docs, this PR
just mentions them there, so people can actually find them.

..and other high level docs.

This implements the `CheckMetadataHash` extension as described in
[RFC78](https://polkadot-fellows.github.io/RFCs/approved/0078-merkleized-metadata.html).

Besides the signed extension, the `substrate-wasm-builder` is extended
to support generating the metadata-hash.

Closes #4366

This bump of versions:

reintroduced a dependency to proc-macro-crate 2.0.0 which is suffering

parity-scale-codec to a newer version to eliminate the bad
proc-macro-crate 2.0.0 dependency.

The issue appears to stem from the `aquamarine` crate failing to render
diagrams in re-exported crates.

e.g. as raised
[here](https://github.com/paritytech/polkadot-sdk/issues/2977), diagrams
would render at `frame_support::traits::Hooks` but not the re-exported
doc `frame::traits::Hooks`, even if I added `aquamarine` as a `frame`
crate dependency.

To resolve this, I followed advice in
https://github.com/mersinvald/aquamarine/issues/20 to instead render
mermaid diagrams directly using JS by adding an `after-content.js`.

derive-syn-parse v0.2.0 came out recently which (finally) adds support
for syn 2x.

Upgrading to this will remove many of the places where syn 1x was still
compiling alongside syn 2x in the polkadot-sdk workspace.

This also upgrades `docify` to 0.2.8 which is the version that upgrades
derive-syn-pasre to 0.2.0.

Additionally, this consolidates the `docify` versions in the repo to all
use the latest, and in one case upgrades to the 0.2x syntax where 0.1.x
was still being used.

Let me know if this structure is adequate.

**Note:** The usage of the words `Merkle`, `Merkelize`, `Merklization`,
`Merkelization`, `Merkleization`, is somewhat inconsistent but I left it
as it is.

~~**Note:** In some places the term `Receival` is used to refer to
message reception, IMO `Reception` is the correct word here, but I left
it as it is.~~

~~**Note:** In some places the term `Overlayed` is used instead of the
more acceptable version `Overlaid` but I also left it as it is.~~

~~**Note:** In some places the term `Applyable` is used instead of the
correct version `Applicable` but I also left it as it is.~~

**Note:** Some usage of British vs American english e.g. `judgement` vs
`judgment`, `initialise` vs `initialize`, `optimise` vs `optimize` etc.
are both present in different places, but I suppose that's
understandable given the number of contributors.

~~**Note:** There is a spelling mistake in `.github/CODEOWNERS` but it
triggers errors in CI when I make changes to it, so I left it as it
is.~~

# Description

This PR adds a reference document to the `developer-hub` crate (see
https://github.com/paritytech/polkadot-sdk/pull/2102). This specific
reference document covers defensive programming practices common within
the context of developing a runtime with Substrate.

In particular, this covers the following areas: 

- Default behavior of how Rust deals with numbers in general
- How to deal with floating point numbers in runtime / fixed point
arithmetic
- How to deal with Integer overflows
- General "safe math" / defensive programming practices for common
pallet development scenarios
- Defensive traits that exist within Substrate, i.e.,
`defensive_saturating_add `, `defensive_unwrap_or`
- More general defensive programming example...
