Adds the follow-up review fixes from #482 to the matrix-parquet v0.8.0 section of release.md. Only the PR's first commit updated the release notes.

Module touched: matrix-parquet (documentation only)

  • Nested type metadata: segments in matrix.nestedTypes paths are escaped (. → \., \ → \\), so dotted column or struct-key names cannot collide. decimalMeta keys are still the raw dotted paths.
  • Timestamp precision: out-of-range LocalDateTime, Timestamp and Instant values now fail before writing, with the column and row in the error. The NANOS range (1677-09-21 to 2262-04-11) is stated.
  • Options: a null timestampUnit entry in an option map now means the MICROS default.

Tests: none run; this change only edits documentation.

🤖 Generated with Claude Code

Document nestedTypes path escaping, pre-write temporal overflow checks
for all temporal classes, and the null timestampUnit option-map default.
