Julius BrusseeandClaude Fable 5 dcd51f16fe fix(compress): stop Windows data loss — UTF-8 + atomic writes (#652, #655, #686)
Every read/write resolved to the locale codec (cp1252/cp949 on Windows):
non-ASCII files were silently mojibake'd, and because Path.write_text
truncates before encoding, a UnicodeEncodeError left the target at 0 bytes.
The backup readback check couldn't catch it — it read back with the same
wrong codec.

- encoding=utf-8 pinned on every I/O call site (compress, validate,
  detect, benchmark); validate now decodes strict — it's the fidelity gate
- write_text_atomic: encode first, temp file in same dir, fsync, preserve
  permissions, os.replace; temp unlinked on any failure
- fix-retry pass gains the same empty-output guard as the first pass
- fix-retry preamble leak (#588): output must start at the original's
  structural anchor (frontmatter/heading) or the attempt is rejected
- primary-write failure now prints the backup path — users hitting the
  crash had no idea a backup existed
- extract_inline_codes: strip fences via the CommonMark-aware extractor;
  the old column-0 regex leaked indented fences into inline-code pairing,
  causing false validation failures (extracted from PR #619's diagnosis)
- SKILL.md/README/SECURITY corrected: backups live in the out-of-tree data
  dir (#420), not beside the source file

Supersedes PRs #683 #678 #626 #534 and the fence fix from #619 with a
local implementation. 58 python tests.
