fetcherVersion = 1 and 2 were deprecated in the 26.05 release and
scheduled for removal in 26.11. Remove them from supportedFetcherVersions
and replace the deprecation warning with a hard throw that points users
at the migration to fetcherVersion = 3.
No in-tree package still uses fetcherVersion = 1 or 2. The now-unreachable
v1/v2 code paths are removed in a follow-up commit.

The pnpm v11 store uses a SQLite database (index.db) whose binary format
is non-deterministic across platforms (version-valid-for number, etc).
This caused hash mismatches when building the same pnpmDeps on different
machines despite identical logical content.
Fix by dumping the SQLite database to a text SQL file during the fetch
phase and reconstructing it during the build phase. This ensures the
stored representation is fully deterministic.

Extend the existing v1 deprecation warning to also fire for
`fetcherVersion = 2`, since callers should migrate directly to
`fetcherVersion = 3`. Both pre-v3 versions now share a single
`lib.warnIf` keyed on `fetcherVersion < 3` and produce a message
parameterised by the offending version.
Consolidate the manual's version-history entries: the per-item
**Deprecated** and **Recommended** labels are replaced by a single
sentence above the list noting that v3 is recommended and v1/v2 are
scheduled for removal.
Add a release note mirroring the existing v1 entry.
fetcherVersion = 1 was kept around for backwards compatibility while
callers migrated to 2/3.
Emit a `lib.warnIf` warning pointing at the affected pname whenever v1
is used.
After 26.11 ships, a follow-up PR should drop 1 from
`supportedFetcherVersions` and clean up the dead v1 code paths in
default.nix, pnpm-config-hook.sh and serve.nix.
Also rewrite the manual section to recommend fetcherVersion = 3 for new
packages and mark v1 as deprecated/scheduled-for-removal in the
version history.

move pnpm.{fetchDeps,configHook} to fetchPnpmDeps and pnpmConfigHook
respectively. Also adds aliases to the former package-level attributes.
Additionally, pnpmConfigHook does not propagate pnpm anymore, to make
changing pnpm versions easier.
This brings pnpm in line with the other Node.js/JavaScript tooling in
nixpkgs.
This doesn't cause any rebuilds.

Adding new packages here is discouraged, for reasons enumerated in
https://github.com/NixOS/nixpkgs/issues/229475, so let's move this
(mostly developer-facing) documentation back into its original location
in pkgs/development/node-packages/README.md.
Move the existing `yarnConfigHook`, `yarnBuildHook` and
`yarnInstallHook` documentation below a Yarn v1 section.
Also move the documentation for the deprecated `yarn2nix` there, which
is Yarn v1 only.
