065ac99224 feat: json encode/decode + as, .wob v2 class metadata — log-watcher compiles
docs/examples/log-watcher (1285 lines, 7 files) now compiles clean: 0
diagnostics, a 35KB .wob written. corpus 71/0, woc runtest 565/0, every wovm
unit gate green (both dispatch flavors).

- .wob v2: each class row gains three u32 per-field arrays — the field's NAME
  constant, the CLASS it refers to (or the json-raw marker), and a container
  field's ELEMENT kinds. json is then a runtime service driven by metadata
  instead of per-type generated code. loader/emitter/disassembler/test
  assembler all read and write v2; field-name constants are interned with the
  rest of the pool (interning during serialization silently loses them)
- runtime/src/json.c (new): encode by static kind + object headers + class
  table (nested records need no static knowledge); decode parses and BINDS
  straight into the target class — keys matched to field names, nested objects
  built as the field's class, arrays as a multi of the field's element kind,
  unknown keys skipped, absent keys nil. Malformed input is nil, never a trap
- `as`: `json.decode(text) as T` is the one cast this language has (WO-E403
  for any other `as`, and for a bare json.decode with no target type). Its
  result is `?T`, which is why the decode and the target are one instruction
- json.Value: a reserved type name for a value the source does not inspect —
  the raw JSON slice, kind TEXT, re-emitted verbatim by encode
- docs: 00-wob-format.md is now the v2 reference (class metadata, TRY/ENDTRY,
  the whole builtin surface, WO_T_IO); 08-builtin-surface.md documents the
  text/container builtins, the OS modules with their predeclared records, and
  json's two documented limits (Bool encodes 0/1, floats truncate)

79605cbb4f feat: milestone 1 complete — .wob emitter, conformance corpus, single binary; GC redesign specced
- `woc` now emits `.wob` that `wovm` runs: emit.ml lowers the typed,
  owner-annotated AST (scope-stack registers with a >64 WO-E401 diagnostic,
  Lua-style call windows, ICALL by slot, dedup const pool, drop maps, line
  tables, implicit terminators); disasm.ml backs `--dump-bc` goldens.
- Ownership lowering consumes the four owner tables verbatim; RESIDUAL is the
  only source of borrow ops, coalesced per operand. Review caught the emitter
  consuming only 2 of owner.ml's 4 residual producers — an assignment-anchored
  aliasing violation ran to exit 0 instead of trapping; fixed, plus a backstop
  raising WO-E404 for any residual region left unconsumed.
- Conformance harness `scripts/oop-e2e.sh` (`just oop-e2e`): four fixture
  kinds with exact outcomes — byte-exact stdout, one WO-E### anchored on
  `error CODE:`, numeric trap code, gc trace. 25 fixtures incl. pricing-demo
  logic, the ownership suite, and DB_STUB's parse-but-trap. `tests/` un-ignored
  so the corpus is actually tracked.
- `woc build` produces a self-contained binary: wovm copy + appended image +
  20-byte trailer, self-exec via /proc/self/exe. Verified relocated outside
  the repo, argless, and against adversarial trailer corruption.
- Milestone 1's five spec criteria all MET (`just oop-accept`). Criterion 3
  closed by WO-E405 — the entry must return `Int`, since program mode already
  says its return value is the exit code — which deletes the leak class
  without adding return-type metadata to the format. `gc/held-cycle` retired:
  an externally-held cycle is not expressible in a post-exit pump.
- New spec: inferred GC + incremental per-shard tri-color mark-sweep, retiring
  `@gc` and reference counting. Story gains iterations 7b (that work) and 9b
  (`@table`, relations, compiler-checked query); `.dev/reference` gains a
  sparse System.Linq checkout. Priority: 5→6→7 (log-watcher) then 7b, 8, 9, 9b.
