הורדת Zero 0.2.0

- Makes canonical .0 text the native source surface, with a parser, formatter, Program import path, diagnostics, docs, examples, stdlib sources, benchmarks, conformance fixtures, and command snapshots aligned around that format.
- Promotes ProgramGraph from inspection output into an editable artifact workflow with deterministic dump, validate, view, check, roundtrip, import, patch, build, run, test, size, and package entrypoint support.
- Adds source-backed graph edits so checked graph patches can rewrite canonical .0 files while preserving package/import context, std helper context, metadata, and stable graph identities.
- Expands direct backend coverage with darwin-x64 Mach-O executable support, shared AArch64 ELF/COFF emission, target-readiness reporting, byte-view ABI fixes, and stronger cross-target buildability checks.
- Adds source-backed std.path, std.str, and std.math modules with docs, examples, Rosetta coverage, and direct target validation.
- Exposes resolved call-resolution and stdlib helper facts in graph JSON, tightening generic return typing, member call facts, std helper validation, and package cache metadata.
- Grows Rosetta and compiler smoke coverage, graph command contracts, metrics budgets, CLI docs, skills, and docs tests around the current agent edit loop.
