feat(typia): align lenient parse recovery with TS parity

[kdy1]

Summary

• align Rust typia lenient JSON EOF recovery with upstream TS behavior
• add upstream parse parity test coverage (66 mapped parse cases)
• expand runtime validate/stringify boundary tests
• sync typia contracts/docs with parity baseline and explicit exclusions

Details

• update crates/typia/src/lenient_json.rs to recover truncated EOF inputs without parser-token errors
• keep syntax/token violations and depth guard as failures
• add crates/typia/tests/llm_json_parse_parity.rs with table-driven parity checks
• update crates/typia/tests/llm_data_runtime.rs expectations for recovery semantics
• update docs:
  • docs/crates-typia-core-foundation.md
  • docs/project-typia.md
  • crates/typia/README.md

Explicit parity exclusions

• JS undefined expectations
• non-finite numbers (Infinity, -Infinity)
• lone-surrogate code-unit expectations

Validation

• cargo test -p typia
• cargo test
