fix(bundle-7): Verification & Tool Suite Execution — wire mandatory scans + first-run evidence

Closes Audit-2026-04-25 D-001..D-002 + D-006 (partial) + H-005 (partial).
Opens new tracker IDs H-010, M-028, L-020, L-021 (see closure document
in cowork/comprehensive-audit-2026-04-25/tool-output/_BUNDLE-7-CLOSURE.md).

What changed
- scripts/install-security-tools.sh (NEW) — idempotent installer for the
  Go-based subset (govulncheck, staticcheck, errcheck, ineffassign,
  gosec, osv-scanner). Used locally + by both CI workflows.
- .github/workflows/security-deep-scan.yml (NEW) — daily + workflow_dispatch
  scans for tools that need docker/network: trivy image, syft SBOM,
  ZAP baseline, schemathesis, nuclei, testssl.sh, gosec, osv-scanner,
  full-suite race detector at -count=10. Every step continue-on-error;
  artefacts uploaded for triage.
- .github/workflows/ci.yml — staticcheck added as a soft (continue-on-error)
  gate alongside the existing govulncheck hard gate. Soft until M-028
  closes the 6 remaining SA1019 deprecated-API sites; flip to fail-on-
  non-zero then. Per-package coverage gates extended: pkcs7 hard ≥85%
  (currently 100%), local-issuer soft ≥65% transitional floor (H-010
  raises to 85%).
- staticcheck.conf (NEW) — suppresses 4 style-only rules (ST1005, ST1000,
  ST1003, S1009, S1011, SA9003) with documented justifications. Real
  defects (SA1019) NOT suppressed.
- .govulnignore (NEW) — empty placeholder with the suppression contract
  (one OSV ID + justification + review-by date per line). Bundle-7's
  5 deferred-call advisories don't need entries because govulncheck's
  default exit code already passes.

Local tool-run evidence (cowork/comprehensive-audit-2026-04-25/tool-output/2026-04-26/):
- govulncheck.txt + govulncheck-verbose.txt — clean (0 affected; 5 deferred-call)
- staticcheck.txt + staticcheck-after-suppressions.txt — 6 SA1019 → M-028
- errcheck.txt — 1294 sites, all defer-Close / response-write convention → triaged
- ineffassign.txt — 15 unique sites → L-020
- helm-lint.txt — clean (1 INFO-level icon recommendation)
- go-test-race.txt — clean across scheduler/middleware/mcp at -count=3
  (CI runs -count=10 against the full suite)
- go-test-cover.txt — crypto 86.7% ✓, pkcs7 100% ✓, local-issuer 68.3% ✗ → H-010

Closures in this bundle
- D-001 partial — 4 of 6 Go-based tools ran locally; remainder wired in CI
- D-002 closed — race detector clean
- D-006 partial — helm lint passes; kube-score / kubesec deferred to CI
- D-007 deferred — semgrep p/react-security wired in CI (needs docker)
- D-003 / D-004 / D-005 deferred — wired in security-deep-scan.yml
- H-005 partial — crypto + pkcs7 meet 85%; local-issuer at 68.3% → H-010

New tracker IDs opened (next-bundle scope)
- H-010 — local-issuer coverage gap (68.3% vs 85% target). 2-3 days.
- M-028 — 6 deprecated-API sites (SA1019). Migration coordinated.
- L-020 — ineffassign cleanup sweep, 15 mechanical sites.
- L-021 — 5 transitive Go-module CVEs (deferred-call). Monitor + bump.

NOT addressed in this bundle (deferred to a future Bundle 7-bis)
- M-007 bulk-operation partial-failure tests
- M-008 admin-gated role-gate tests
- L-010 mock.Anything overuse audit
- L-018 defect age analysis on remaining High findings

Verification
- go vet ./...                                → clean
- go build ./...                              → clean
- go test -short -count=1 ./...               → all packages pass
- go test -race -count=3 ./scheduler/middleware/mcp → clean
- go test -cover ./crypto/pkcs7/local-issuer  → see go-test-cover.txt
- govulncheck ./...                           → clean
- staticcheck ./...                           → 6 SA1019 (tracked as M-028)
- helm lint                                   → clean
- yaml lint .github/workflows/*.yml           → clean
- python3 yaml.safe_load(api/openapi.yaml)    → 89 paths
