Zero 0.2.1 பதிவிறக்கம்

- Adds extern C call support with target-aware header preprocessing, stricter link-plan validation, direct object linking, graph metadata fixes, and diagnostics for missing or unsafe C import inputs.
- Expands the standard library across memory, collections, search, sort, ASCII, formatting, text, parsing, math, random, time, codec, JSON, URL, hosted I/O, filesystem, HTTP, testing, and logging helpers.
- Strengthens memory-safety diagnostics for Maybe guards, owned moves, mutable span aliases, span lifetime escapes, aggregate reassignment, scalar match fallthrough, and exported safety facts.
- Improves direct backend correctness across Mach-O, ELF64, COFF, x64, and AArch64 paths, including byte-view bounds, checksum helpers, open slices, usize runtime returns, and indexed store handling.
- Retires row source parsing from the public source boundary, keeps canonical .0 text as the supported input surface, and rejects stale row graph artifact paths.
- Refreshes docs, examples, skills, command contracts, conformance fixtures, stdlib contracts, target-matrix checks, compiler metrics, and reliability smoke coverage around the current workflows.
