shoney.arickathil fb91085bdb feat: systems stdlib OS half — fs, time, env, net, proc
log-watcher diagnostics 129 -> 55 (json is what is left: 13 encode sites,
3 `as` parses and their cascade). corpus 71/0, woc 565/0, wovm gates green.

- runtime/src/sysio.c (new): 17 builtins behind the reserved module names —
  fs.exists/list/stat/read_all/read_at/append, time.sleep/local/iso,
  env.get/stopping, net.listen/accept/read/write/close, proc.run. Thin
  blocking libc calls; a failed syscall traps the new WO_T_IO with errno's
  own message, which `try ... catch` is how a program handles
  - record-returning members (fs.stat, time.local, proc.run) take their
    result record's CLASS ID as the last argument, so the VM allocates what
    it fills without knowing any source type name (the err_fill pattern)
  - absence is the zero word: a missing path from fs.stat and an unset
    env.get are nil, not traps
  - env.stopping installs SIGTERM/SIGINT handlers on first use only
- types.ml: predeclared Stat/TimeParts/Proc records (field order is the
  contract with sysio.c) + the stdlib member table (arity, builtin id,
  return type, result record) + stdlib return types in confident_typ
- emit.ml: stdlib member calls lower to their builtin with the record class
  id appended; WO-E406 now means "no such member", not "not linked";
  predeclared records enter the class table only when a program needs them
- emit.ml: fstate carries the method's declared return type, so a tail
  `return []` / `return {}` gets its element kinds; a non-empty list literal
  falls back to its own element type when there is no declared destination
- types.ml: confident_typ chases a container read (`c[i]`), which is what
  makes a switch over a value pulled out of a map resolve; a void `try` arm
  no longer demands its catch arm agree
- corpus: lang-use-stdlib-not-linked now pins WO-E406 for an unknown MEMBER
  (fs.slurp) — the "not linked" premise is gone now that fs is linked

tests/corpus/ — the conformance spine

Fixture kinds, exact-outcome matching (byte-equal stdout / exact WO-E### / exact trap code / exact gc step+freed counts):

dir kind landed by plan
run/ compiles + runs, expected stdout 3
compile-fail/ must fail with expected WO-E### 3–4
trap/ must trap with expected code 3–4
gc/ cycle collection scenarios 3
actor/ shard/spawn/send (ASan+TSan) 4
db/ insert/select + crash/replay 5
lang/ Haxe-parity adoptions 8
sys/ fs/proc/net/time/json stdlib 9
sample-logwatcher/ ported log-watcher fixtures 10

Runner: scripts/oop-e2e.sh (plan 3, task 2 — includes the how-to-add-a-fixture doc pointer docs/plan/oop-vm/02-corpus.md).
