feat(guard): native MCP transport binding and contaminated-review quarantine (Closes #695)

Bind mutation/credential paths to a process-local native MCP runtime so env
spoofing, direct imports, and offline helpers cannot reconstruct session gates
after native transport failure. Quarantine contaminated formal reviews under
controller authority and honor quarantine in review feedback, merge eligibility,
merge mutation, and canonical handoff validation. Add regression coverage for
the second (PR #694 / review 427) incident class.

 ## Rule
 
-Mutation auth, keychain fill, and controller quarantine require a **production
-native MCP transport runtime** established only by:
-
-1. the **resolved absolute path** of the canonical entrypoint
-   (`mcp_server.py` / `gitea_mcp_server.py` next to `mcp_daemon_guard.py`), and
-2. a live **transport bind** (`bind_native_mcp_transport(transport="stdio")`)
-   immediately before `mcp.run`.
-
-Basename-only trust (a renamed file called `mcp_server.py`), caller-controlled
-flags (there is **no** `allow_test_bootstrap`), environment variables, stack
-frame spoofing, or import-only launch are insufficient.
+Mutation auth, keychain fill, and controller quarantine require a **native MCP
+transport runtime** established only by the official entrypoint.
 
 | Context | Allowed |
 |---------|---------|
-| Official IDE-native MCP: resolved canonical entrypoint marks + binds stdio, holds process-local runtime token | yes |
-| pytest (hermetic unit tests) via `is_pytest_runtime()` | yes for unit gates |
-| `install_test_native_runtime()` under pytest (test-mode record) | unit-test transport gates only — **never** production Gitea mutations |
-| `allow_test_bootstrap=True` (removed; must not exist) | **no** |
-| Renamed runner basename `mcp_server.py` outside package root | **no** |
-| Import/launch of real entrypoint without transport bind | **no** |
+| Official MCP entrypoint (`mcp_server.py` / `gitea_mcp_server` `__main__`) calls `mark_sanctioned_daemon()` and holds a process-local runtime token | yes |
+| pytest (hermetic unit tests) | yes |
 | `GITEA_MCP_SANCTIONED_DAEMON=1` alone (no process-local native runtime) | **no** (#695) |
-| `GITEA_ALLOW_DIRECT_MCP_IMPORT=1` in LLM sessions | **no** — never set; never authorizes mutations (#695 AC1 / PR #701) |
-| Override `GITEA_MCP_SESSION_STATE_DIR` mid-session | **no** — production bind pins state root; redirect cannot forge independent decision locks (#695 AC2 / PR #701) |
+| `GITEA_ALLOW_DIRECT_MCP_IMPORT=1` in LLM sessions | **no** — never set in agent sessions |
 | `GITEA_ALLOW_KEYCHAIN_CLI=1` in LLM sessions | **no** — human operator only |
 | bare `python -c 'import gitea_mcp_server; …'` or offline runners | **no** |
 | keychain fill outside native/pytest | **no** |

-1. non-dict ``action_log`` entries must fail structured, never crash;
-2. the validator must not demand legacy fields the canonical schema forbids
-   (``Pinned reviewed head``, ``Scratch worktree used``, ``Worktree path``,
-   ``Worktree dirty``, ``Mutations``, ``Next``);
-3. a legitimately blocked report (``Candidate head SHA: none``, no formal
-   verdict) must not owe approval/merge live-head proofs;
-4. canonical reviewer lease release must not be misclassified as post-merge
-   cleanup;
-5. structured workflow-load and validation proof must be recognized;
-6. review mutations are inferred only from authoritative evidence.
