This PR replaces `find -print0 | xargs -0 -I{} sh -c '...'` with
`find -print0 | while IFS= read -r -d '' f; do ... done` for the
subverso sub-manifest sync in release_steps.py. The original xargs
invocation had fragile nested shell quoting; the while-read loop is
both null-delimiter safe and more readable.

This PR fixes `release_steps.py` for `verso`. After running `lake
update` in the root, the `test-projects/*/lake-manifest.json` files
retain stale subverso pins, causing verso's "SubVerso version
consistency" CI check to fail. The fix syncs the root manifest's
subverso rev into all test-project sub-manifests.
Root cause: verso has nested Lake projects in `test-projects/` each with
their own `lake-manifest.json`. Running `lake update` in the root
updates the root manifest but doesn't touch the nested ones.

This PR fixes a release workflow bug where the reference-manual
repository would get tagged with a stale release notes title (e.g.,
still showing "-rc1" for a stable release).
The root cause was a sequencing issue: `release_steps.py` didn't update
the release notes title when bumping the reference-manual toolchain, and
`release_checklist.py` only checked the title while the bump PR was
open. Once merged, it went straight to tagging without rechecking.
Two fixes:
- `release_checklist.py`: add a title correctness check before tagging
reference-manual (blocks tagging if the title is wrong)
- `release_steps.py`: automatically update the `#doc` title line in the
release notes file when bumping reference-manual (handles both
RC-to-stable and RC-to-RC transitions)

This PR adds automatic ProofWidgets4 version pin updates to
`release_steps.py` when processing mathlib4. ProofWidgets4 uses
sequential version tags (`v0.0.X`) rather than toolchain-based tags
(`v4.X.Y`), so the existing regex that updates dependency versions in
lakefiles doesn't match it. This has caused CI failures in two
consecutive releases where the mathlib4 PR was created with a stale
ProofWidgets4 pin.
Changes:
- `script/release_steps.py`: Add `find_proofwidgets_tag()` to look up
the latest ProofWidgets4 tag compatible with the target toolchain, and
use it to update mathlib4's lakefile automatically
- `doc/dev/release_checklist.md`: Document the ProofWidgets4 pin update
step for mathlib4

This PR updates the release checklist script. The cslib repository no
longer has a docs subdirectory, so the release script was failing when
trying to update lakefile.toml and lean-toolchain in that nonexistent
directory.
This PR improves the scripts assisting with cutting Lean releases (by
reporting CI status of open PRs, and adding documentation), and adds a
`.claude/commands/release.md` prompt file so Claude can assist.
This PR further improves release automation, automatically incorporating
material from `nightly-testing` and `bump/v4.X.0` branches in the bump
PRs to downstream repositories.
This PR further updates release automation. The per-repository update
scripts `script/release_steps.py` now actually performs the tests,
rather than outputting a script for the release manager to run line by
line. It's been tested on `v4.21.0` (i.e. the easy case of a stable
release), and we'll debug its behaviour on `v4.22.0-rc1` tonight.
This PR improves the release checklist and scripts:
* Check that the release's commit hash is not all-numeric starting with
0 (this can break SemVer, which [required us to release
v4.21.0-rc2](https://github.com/leanprover/lean4/releases/tag/v4.21.0-rc2)).
* Check that projects being bumped to a release tag do not reference
`nightly-testing` anymore.
* Clarify how to create subsequent release candidates if an `-rc1`
already exists.
* Fix typos in the release checklist documentation.
This PR adds further automation to the release process, taking care of
tagging, and creating new `bump/v4.X.0` branches automatically, and
fixing some bugs.

This PR fixes a number of bugs in the release automation scripts, adds a
script to merge tags into remote `stable` branches, and makes the main
`release_checklist.py` script give suggestions to call the
`merge_remote.py` and `release_steps.py` scripts when needed.
