[PR] fix(spec): preserve exact schema and temporal value semantics [iceberg-rust]
aarushigupta132 opened a new pull request, #3077:
URL: https://github.com/apache/iceberg-rust/pull/3077
## Which issue does this PR close?
Prerequisite for the focused UpdateSchema series split from #3069.
## What changes are included in this PR?
- Parses and formats the full Iceberg i32 date and i64 microsecond timestamp domains instead of being limited by chrono calendar ranges.
- Preserves exact microsecond fractions and handles extended proleptic-Gregorian years in JSON and display paths.
- Makes case-insensitive schema lookup reject names that differ only by case instead of selecting one nondeterministically.
- Makes schema equivalence independent of identifier-set iteration order and consistent with Java floating-point equality for defaults.
This is independently mergeable and contains no transaction or schema-evolution API.
## Are these changes tested?
Yes. Coverage includes temporal range boundaries, pre-epoch values, extended years, offsets and fractional rendering, ambiguous schema names, identifier-set ordering, NaNs and signed zero. All 1,590 iceberg library tests, 89 doctests, formatting, diff checks, and all-feature library Clippy pass.
