Krzysztof kuhy Rudnicki 9f271b0d37 Fix the cap hook in CI, and the re-exports its --all-files run exposed
The hook entry was an absolute /home/kuhy/utils path, copied from a config
written for ~/.claude where it only ever ran locally. On an Actions runner
that is exit code 127 — "No such file or directory" — so gatelock-precommit
and crdt-sync-precommit failed on every commit of this refactor while the
hook silently checked nothing. Now repo-relative, matching the sibling hooks
(`entry: scripts/check_subproject_scope.sh`): pre-commit always runs from the
git root, so it resolves the same in both places.

Fixing that made the CI configs runnable locally, and `--all-files` then found
what per-file runs had missed — ruff pruning imports that exist *for* their
re-export. `import crdt_sync` was broken three separate ways (FileSyncStateStore,
encode_key, FileCredentialStore). Each affected module now states an explicit
__all__ so the autofixer cannot take them again, and the two files that pushed
past the cap once __all__ was added are split further:

  _firebase.py 260 -> 247 + _fberrors 25
  _sync.py     257 -> 188 + _syncargs 91

Test patch targets followed the code they patch: gatelock._outputs.shutil ->
_xrandr.shutil, gatelock._arbiter.Path -> _claims.Path.

gatelock and crdt-sync both pass `pre-commit run --all-files` in full;
389 and 259 tests at 100% branch coverage; the root gate exits 0.

# Repo-wide gate for the shared 250-line file cap (refactor_claude_todo.md).
#
# A file that cannot be read in one piece forces re-reads and partial edits,
# which is the largest avoidable cost in an LLM-assisted workflow. A refactor
# without a gate silently regrows, so this is the part that makes it stick.
#
# Checks only the files in the commit, so an unrelated commit never breaks on
# a violation it did not introduce, and it FAILS (exit 1) rather than warning.
# No baseline and no allowlist -- those are suppressions.
#
# The subprojects (gatelock/, crdt-sync/, web_ui/, design_system/,
# sync_settings_ui/) each keep their own .pre-commit-config.yaml for their own
# linters, and carry this same hook so committing with one of those configs is
# gated too. This root config is what `pre-commit install` wires up, and it is
# the only one that covers the subprojects without a config of their own
# (aur-publish/, guard-lib/, crdt_sync_dart/, file_length/, ...).
#
# The path is repo-relative on purpose. pre-commit always runs hooks from the
# git root, so this resolves the same locally and on a CI runner -- an absolute
# /home/... path exits 127 in Actions, which is how this was first written.
