Marc-André BombeckandClaude Opus 4.7 58ae9bca42 feat(coach): partial-malformed observability on sentinel parser ...

The W3-of-v1.4.22 sentinel parser silently dropped malformed rows and
fired `coach.keyvalues.parse_failed` only when the entire block was
unusable. Mixed-format drift (one row breaks, the other six parse)
landed without any signal. Surface it.

- `SentinelParseResult.malformedEntries[]` records each skipped row
  with a typed reason (`missing_colon` / `value_overflow` /
  `label_overflow` / `no_END_marker` / `byte_overflow` /
  `schema_invalid`). Block-level failures (truncation, missing close
  marker) land here as synthetic entries so the wide-event always
  carries a typed cause.
- Per-row label and value caps moved out of the Zod schema into the
  parser so the row-level reason can be `label_overflow` /
  `value_overflow` rather than the catch-all `schema_invalid`.
- Chat route splits the annotation: `coach.keyvalues.parse_partial`
  when at least one row parsed AND at least one row failed, the
  existing `coach.keyvalues.parse_failed` stays for full-block
  failures. Both annotations carry the per-line reason array.
- Backwards-compatible `parseKeyValueLine` wrapper preserved.

Tests +5: label_overflow, value_overflow, byte_overflow,
mixed-malformed entry assertions, and a tryParseKeyValueLine
direct-API surface check.
