docs: AGENTS.md + refresh README/roadmap/summary/SESSION_HANDOFF to P4 canon; rm empty logs

- AGENTS.md: canonical build/test commands, honest trimmed tone metric, current
  bit-exact state (mask-apply chain), open gaps (PRNG/FFT-conv/exp2/SR-mismatch).
- README.md: status moved to P4 (C++ FramedDetector canon, framed_test), historical
  B.1..B.15 numerical model demoted to <details>; structure/doc table updated.
- roadmap.md: P4 phase marked progress, P4.1/P4.2/P4.3 milestones, top status refresh.
- summary.md: marked historical (behavioral v4).
- SESSION_HANDOFF.md: fixed stale "NOT DECODED" (now decoded), copy note done.
- Removed empty tmp_spec.txt/giant3.txt and untracked .log/__pycache__ clutter.

 ## 0. DECOMPILATION INVENTORY (2026-08-19 — what's decoded, where, and what's missing)
 Goal: bit-exact parity is gated by EXACT tables/window/constants. The chunk-level model hits
 err ≤0.62 dB (dual) / ≤0.19 dB (al_*) — to go sample-exact we need precise values from the binary.
