shoney.arickathil 9812f3d396 feat: bounded mailboxes + WO_T_ACTOR (trap 13); try-arm place-copy fix

- cap 1024 (WO_MAILBOX override at boot): sender-side atomic
  reserve/release on every path — same-shard, cross-shard envelope,
  OOM rollbacks; full mailbox traps the SENDER catchably; delivery
  pop releases; overshoot bounded by in-flight sends (disclosed)
- test_mailbox 12/0: exact cap single-threaded, two racing senders win
  exactly cap slots, drain/refill clean
- corpus run/mailbox-full-trap: parked sleeper, send loop catches
  "actor mailbox full" after >= 1024 sends
- pre-existing compiler bug found + fixed: a try ARM yielding a Text
  PLACE (bare e.msg, try box.field) aliased a register the arm's scope
  end freed — ASan use-after-free, SEGV on the next unwind's
  double-walk; emit_try now applies copy_place_text to both arm
  results; pinned by corpus run/catch-msg-place
- db-bench driver: msgrate keeps iteration 22's unbounded-flood
  contract via WO_MAILBOX=MSG_N (the cap is 24's policy, not 22's)
- battery 12/12 fresh-built
