Fix codespell-flagged typos to align with trunk

Ran codespell with the backported ignore-words list and applied its
corrections (--write-changes), fixing 52 spelling errors across 44
files. All are in comments, strings, and log messages (e.g. unknwon ->
unknown, shuting -> shutting, Retrives -> Retrieves); no code
identifiers were touched. Each typo was verified absent from trunk
beforehand, so these fixes reduce divergence rather than add it.

Phase 1 backport (A_FORMAT + B_CI_DOCS), codespell step.

Apply pre-commit hooks to align whitespace formatting with trunk

Ran 'pre-commit run --all-files' using the config backported in the
previous commit. The auto-fixing hooks (trailing-whitespace,
end-of-file-fixer, mixed-line-ending, insert-license) normalized 115
files. Verified the changes are whitespace/EOL/EOF-only plus Apache
license-header insertion on README files; no source content changed
(confirmed via 'git diff --ignore-all-space').

This replaces replaying ~350 historical formatting commits (which
conflicted with AOO42X's own independent whitespace passes) with a
single deterministic reformat that matches trunk's tooling.

Phase 1 backport (A_FORMAT + B_CI_DOCS), reformat step.
