Release notes

- Makes graph patching the primary agent edit loop with stdin patch bodies, --replace-in-fn, expression replacement by handle, structural rewrites, declaration-level edits, helper/test patch ops, and inline handle diagnostics across view, query, and patch commands.
- Improves graph/source reconciliation with patch-specific stale-refresh tips, once-per-state notes, accepted whole-file rewrites when function sets are preserved, and clearer unsupported graph-test and non-entry World helper diagnostics.
- Speeds up graph workflows with memoized repository store loads, adjacency orders, semantic check verdicts, static const classification, pre-merge MIR cache keys, and reusable runtime object cache artifacts.
- Reduces direct backend output and broadens native coverage with constant array-fill loop lowering, COFF x64 HTTP request-body extraction, chunked file reads via std.fs.readBytesAt, and total-file-size reporting for fixed-buffer reads.
- Refreshes bundled skills, CLI help, docs, command contracts, conformance fixtures, compiler metrics, and validation guidance around the patch-first agent workflow.
- Hardens release checks with runtime object cache cleanup, graph patch routing coverage, examples gate teardown retries, and additional package cache/version assertions.
