feat: plan 16 P1 complete (SEC-07 approval + SEC-10 agent identity)

- SEC-07 (M-08): real approval verification via approval-verify.sh in enforced mode
  (CASAN_PROFILE=prod / CASAN_APPROVAL_STRICT=1) for control-plane `set` (sensitive
  keys), kill-switch `clear`, and self-improve (inherits control-plane). A bare or
  forged approval string is now denied; dev mode stays backward-compatible.
- SEC-10 (M-05): non-spoofable agent identity. tool-registry-gate least-privilege no
  longer trusts CASAN_AGENT env in enforced mode (CASAN_IDENTITY_STRICT=1) — the
  caller must present a signed token (agent-identity-sign.sh) bound to agent id +
  run id, verified against agent-identities.registry. Blocks env spoofing + replay.

Verify: SEC+integrity gate 18/0, run-casan4 0-FAIL, adversarial 44/44 (H2 intact),
control-plane 9/0, h5-approval 12/0, c7-incident 15/0, self-improve 7/0, track-c 29/0.

Plan-16 P0 + P1 now complete; remaining: P2 (SEC-12/13/14/15/22..30).
