docs(phase-16): PIVOT — m2c+permuter won't crack the loose-typed core; new plan + harness fixes

- docs/struct-core-pivot.md: findings + decision + new research directions. Root cause = the
  original engine is LOOSELY TYPED (K&R; same fn called with int/ptr, arg/no-arg across sites),
  so no single canonical signature exists -> m2c guesses inconsistently, permuter can't fix
  semantics, byte-gate (correctly) rejects. Yields ~3%, not the crack. New plan: emulator-recover
  the actor struct/types -> Ghidra global type propagation -> Ghidra-C -> permuter+gate.
- harness bug-fixes (REAL, kept): p16_permute output-0-only match (killed the false '42%'),
  base.c keeps callee externs, winner_to_draft line-strip; sig_unify canonicalizes m2c's
  no-extern prototypes; gen_engine_decls.py (documents why a global canonical header breaks
  loose-typed matches).
- a few byte-gated leaf matches banked in ov_SC01_077.c.

feat(phase-16): wire the permuter into auto_driver (the near-miss yield lever)

- driver per-fn flow: m2c -> match_one prefilter -> if near-miss & --permute-secs>0, run
  decomp-permuter (time-boxed, reuses p16_permute setup/run) -> use the score-0 winner as the
  draft -> whole-binary byte-gate. The permuter is closing near-misses well in the overnight
  batch, so it's the driver's core yield step for the unattended run.
- +--permute-j (RAM-bound on the 15GiB box).

feat(phase-16): S5 driver+supervisor+safe-exit + NULL fix + sig_unify pipeline

- common.h: +NULL (byte-neutral; recovers 54/106 m2c CC1-fails that were just NULL-undeclared)
- tools/auto_driver.py: never-stop worklist loop (m2c -> sig_unify -> byte-gate -> propagate ->
  commit), STOP-sentinel safe-exit at every fn boundary, heartbeat.json
- tools/auto_supervisor.sh (pure-bash babysitter, relaunch-on-crash, reap permuters, MCP-off),
  auto_stop.sh (touch .run/auto/STOP), auto_status.sh (remote check-in)
- p16_known_answer.py: +--gate (whole-binary capability test)
- YIELD REALITY (honest, P9): macro+sig_unify whole-binary = 4/16 (25%) on KNOWN-matchable,
  ~1% on the unmatched hard tail. The permuter is the untested differentiator -> overnight test.
- CURRENT_PHASE: full night's findings + Drew's never-stop/safe-exit/graduated-ladder refinements
