mcp(coverage): add 34 tools across 7 domains to close 2026-05-05 parity audit P1 findings

Closes findings P1-1..P1-35 from the 2026-05-05 CLI/API/MCP↔GUI parity
audit (cowork/cli-gui-parity-audit-2026-05-05/RESULTS.md). Before this
bundle, 35 operator-facing API endpoints had GUI surfaces but no MCP
counterpart — operators using AI assistants for cert lifecycle work in
regulated environments had to drop to curl for approve/reject, health-check
acknowledgement, renewal-policy CRUD, network-scan triggering, discovery
triage, intermediate-CA management, and job verification.

Tool count: 87→121 in tools.go (+34), 6 unchanged in tools_est.go.
Re-derive via grep -cE 'gomcp\\.AddTool\\(' internal/mcp/tools.go
internal/mcp/tools_est.go.

The 7 phases (matching the bundle prompt at
cowork/mcp-coverage-expansion-prompt.md):

  Phase A — Approvals (P1-28..P1-31, 4 tools)
    list_approvals, get_approval, approve_request, reject_request.
    Two-person-integrity contract (ErrApproveBySameActor → HTTP 403)
    is preserved automatically: the decided_by actor is derived
    server-side from middleware.UserKey, NOT from request body, so
    the MCP server's authenticated API-key identity becomes the
    audit-trail actor. The MCP input schema deliberately omits any
    actor_id field to prevent client-side spoofing.

  Phase B — Health Checks (P1-20..P1-27, 8 tools)
    list, summary, get, create, update, delete, history, acknowledge.
    Mirrors the existing target-resource shape; acknowledge takes
    optional 'actor' string captured in the audit row (handler defaults
    to 'unknown' if absent).

  Phase C — Renewal Policies (P1-1..P1-5, 5 tools)
    Standard CRUD against /api/v1/renewal-policies. Distinct from the
    legacy 'policy' tools that point at the same path — these expose
    the renewal-policy domain explicitly with full alert_channels +
    alert_severity_map field shape.

  Phase D — Network Scan Targets (P1-14..P1-19, 6 tools)
    CRUD + trigger_scan. trigger_network_scan returns the discovery-
    scan body so the AI can chain into list_discovered_certificates
    filtered by agent_id.

  Phase E — Discovery read-side (P1-10..P1-13, 4 tools)
    list_discovered_certificates, get_discovered_certificate,
    list_discovery_scans, discovery_summary. Complements the
    pre-existing claim/dismiss tools (registered alongside Health
    historically per the I-2 closure).

  Phase F — Intermediate CAs (P1-6..P1-9, 4 tools)
    list, create (root + child via discriminator on body shape), get,
    retire. The handler is admin-gated via middleware.IsAdmin; the
    least-privilege boundary is enforced at the API layer (HTTP 403
    for non-admin Bearer callers) — not by transport carve-out.

  Phase G — Verification + deployments (P1-32, P1-34, P1-35, 3 tools)
    list_certificate_deployments, verify_job, get_job_verification.
    P1-33 (POST /api/v1/agents/{id}/discoveries) is intentionally
    excluded — machine-to-machine push channel for agents reporting
    filesystem-scan results, not an operator-driven flow. Documented
    inline in the RegisterTools dispatch.

Implementation:
  - 14 new input types in internal/mcp/types.go with jsonschema struct
    tags driving LLM tool discovery.
  - 7 register* functions in internal/mcp/tools.go each handling one
    phase, wired into RegisterTools dispatch in declaration order.
  - 34 new entries in tools_per_tool_test.go::allHappyPathCases —
    the existing in-process MCP harness (TestMCP_AllTools_HappyPath +
    TestMCP_AllTools_ErrorPath + TestMCP_RegisterTools_DispatchableToolCount)
    auto-extends coverage to cover every new tool: happy-path round-
    trip with fence-shape assertion, 5xx error-path with MCP_ERROR fence
    propagation, and 'every registered tool is dispatchable' guard.
  - docs/reference/mcp.md 'Available Tools' table expanded from 16 to
    22 resource domains with current per-domain tool counts.

Acceptance gate (verified):
  - go build ./cmd/server/... ./cmd/agent/... ./cmd/cli/... ./cmd/mcp-server/...
    clean across all four production binaries.
  - go vet ./... clean.
  - go test -short -count=1 ./internal/mcp/... pass (TestMCP_AllTools_*
    expanded to 127 tool round-trips).
  - go test -short -count=1 ./... pass repo-wide.
  - bash scripts/ci-guards/openapi-handler-parity.sh clean (router 178,
    OpenAPI 144, exceptions 36 — unchanged; we add MCP wrappers, not
    routes).
  - gofmt -l clean across the four touched files.
