fix(docs): add required MDX frontmatter to AGENTROUTER_WAF.md

Missing title/version/lastUpdated frontmatter broke the production build
(fumadocs-mdx requires title on every docs/**/*.md file).

-- **chore(tests):** cleared two base-reds sitting on `release/v3.8.50` itself, both of which turned every open PR red the moment it merged the release. `tests/snapshots/provider/translate-path.json` was stale: #9064 added the `code-execution-2025-08-25` and `skills-2025-10-02` beta flags to the Anthropic header without regenerating the golden, so `provider-translate-path-golden` failed on the bare release tip (2 pass / 1 fail with zero PRs boarded). And `tests/unit/v1-models-auth-leak-9320.test.ts:83` shipped a `(k: any)` in a file new enough that `config/quality/eslint-suppressions.json` does not cover it — with `@typescript-eslint/no-explicit-any` set to `error` under `tests/`, that single cast failed the `No new ESLint warnings` gate repo-wide. Same class in `tests/unit/issue-9407-gemini-web-validation-false-positive.test.ts:50` (`(executor as any).testConnection`), which entered at `f1ea77fd04` — `testConnection` is a declared public method on `GeminiWebExecutor`, so that cast was redundant too. Regenerating the snapshot and dropping both casts restores the gates.

Adds a `hasDeclaredEffortTiers` gate (skip the synced-coverage suppression when the static model declares its own supportedThinkingEfforts list) and calls the existing getThinkingCapabilityFields(...) helper — now with a new skipCanonicalEffortFallback flag — to spread thinking/effort_tiers fields onto both the alias and provider-prefixed model entries. DeepSeek V4's thinking-effort tiers (minimal/low/medium/high) were being silently suppressed by the synced-model-coverage guard added for #7786, and any effort variant not explicitly declared fell back to synthesizing unresolvable `<prefix>/<model>-{tier}` ids for every static reasoning model. All the actual field-computation logic (hasDeclaredTiers, effort_tiers selection, extendCodexGpt56EffortValues fallback) lives in the non-frozen leaf src/app/api/v1/models/catalogHelpers.ts::getThinkingCapabilityFields; catalog.ts only adds the 5-line gate + destructure + spread at its single static-model push site. Cohesive wiring at the existing chokepoint, mirroring prior thinking/vision-field rebaselines (#4264 supportsVision, #6218-era supportsThinking) at the same site; not extractable further without hiding the per-model field-merge boundary.

Fixes a real bug where a reverse-conversion proxy (text-Intent/JSON to Claude Code native tool_calls) rewrites assistant messages between agentic tool-loop turns, breaking HyperAgent's conversation-prefix fingerprint and cold-starting the thread mid tool-loop. Adds Anthropic tool_use/tool_result flattening to extractMessageText() plus a new rootUserFingerprint()/root-key lookup tier in resolveHyperAgentThreadBinding()/storeHyperAgentThreadAfterTurn() so the thread stays sticky across the tool loop. Cohesive additions inside the existing single-file executor; not extractable without splitting the executor mid-request-flow. Covered by tests/unit/executor-hyperagent.test.ts (19/19, +5 new cases for tool_result/tool_use flattening + root-key stickiness). Pre-merge review flagged a cross-conversation root-key collision risk (tracked in the PR's own mandatory pre-merge checklist, not yet addressed) — unrelated to this file-size ratchet, tracked separately by /fix-prs.",

Fixed by adding a single `isGraphqlFailure()` type-predicate helper (doc comment + 3-line body) reused at both call sites instead of duplicating the predicate inline — not extractable to a shared module without splitting a single-file executor's local narrowing helper out of its own file.

-# Management Authentication
-
-OmniRoute uses four distinct credential families for management access. This guide
-distinguishes them by purpose, scope, and locality.
-
-| Credential              | Scope              | Locality      | Use Case                          |
-|-------------------------|--------------------|---------------|-----------------------------------|
-| Dashboard JWT session   | Full management    | Localhost      | Web dashboard login               |
-| CLI machine-id token    | Full management    | Per-machine    | `omniroute` CLI commands          |
-| Scoped `oma_` token     | Configurable scope | External       | Automation / CI / API access      |
-| Manage-scope API key    | `manage` scope     | External       | Management API calls              |
-
-## Dashboard JWT Session
-
-Generated on dashboard login (`/api/auth/login`). Stored in HTTP-only cookie.
-Valid for the session duration. Cannot be used from external hosts.
-
-## CLI Machine-ID Token
-
-Created by `omniroute auth login` on first use. Stored in `~/.omniroute/auth.json`.
-Used by the CLI for all management operations. Tied to the machine identity.
-
-## Scoped `oma_` Access Token
-
-Created via dashboard or CLI with configurable scopes (e.g., `manage`, `read`).
-Format: `oma_<random-hex>`. Used for programmatic access from external systems.
-
-## Manage-Scope API Key
-
-Standard API key with the `manage` scope enabled. Created in dashboard API Keys page.
-Used for management API calls from external hosts.
-
-## Header Examples
-
-```
-Authorization: Bearer oma_abc123def456
-Authorization: Bearer <standard-api-key-with-manage-scope>
-Cookie: omniroute_session=<jwt-token>
-```
-
-See `docs/reference/API_REFERENCE.md` for endpoint-specific auth requirements.
