test(web-tools): cover contract placement edge cases

The <tool> contract from prepareToolMessages was prepended as the first
system message. Web executors fold all system messages into one block, so
with agentic clients whose system prompts exceed ~28K chars the contract
sat at the head of a huge block and web models ignored it, refusing tool
calls with "tool X is not in my tool set" (chatgpt-web, 0/3 at 30K chars).

Two changes, both required in testing:

- Dual placement: the full contract now rides as a trailing system
  message (folds to the tail of the system block) and a one-line
  reminder naming the tools is appended to the latest user message.
- Rewording: the contract now frames injected tools as client tools
  invoked via a plain-text protocol, distinct from the model's native
  tool registry (web.run, python.exec, ...), and instructs the model to
  never claim they are unavailable. Without this the model resolved
  tool names against its native registry and refused even when it had
  seen the contract.

Measured on cgpt-web gpt-5.5-thinking/gpt-5.6-thinking/o3: prepend 0/3
tool calls at 30K chars; dual placement 16/17 across 30K-250K system
prompts, 30-tool sets, multi-turn tool history, streaming, and 3-way
concurrency, with no spurious calls on no-tool prompts. Known limit:
~40K-char single user messages still flake (2/3) due to the upstream
model's own injection heuristics.

All prepareToolMessages consumers parse system messages
position-independently and select the current user turn by role scan,
so the trailing system message is shape-safe for every web executor.

-/**
- * Warm-startup + parallel-refresh tests for the opencode-plugin config shim.
- *
- * Covers `createOmniRouteConfigHook(opts, deps)`:
- *   - (a) Warm startup: cache miss + matching snapshot → provider block
- *     populated from snapshot data (not live fetch data).
- *   - (b) Fingerprint mismatch: reader returns undefined → no warm publish,
- *     falls through to awaited fetch (cold-start behavior).
- *   - (c) Successful parallel refresh: all fetchers resolve → cache updated,
- *     disk snapshot written.
- *   - (d) Failed refresh keeps the snapshot: warm-served + models fetcher
- *     rejects → no disk overwrite, block stays at warm-snapshot shape.
- *   - (e) Parallelism: all six fetchers start concurrently (not sequential).
- *   - (f) Soft-fail parity under Promise.allSettled: per-endpoint
- *     fallbacks + logger.warn breadcrumbs preserved.
- *   - (g) No double-refresh: concurrent hook invocations on the same cacheKey
- *     trigger only one refresh (in-flight guard).
- *   - (h) features.diskCache: false disables the warm read entirely.
- *
- * Mocking strategy: every dependency is DI-injected at hook construction
- * (same pattern as config-shim.test.ts). No global monkey-patching.

-feature: 9490
----
-
-**Warm catalog startup from disk snapshot + parallel refresh** (opencode-plugin): The config-shim hook now reads the last disk snapshot *before* fetching, so the provider registers immediately with the last-known-good catalog (~1-2s vs ~30s on a warm gateway). All six fetchers run concurrently via `Promise.allSettled` instead of sequentially. A failed refresh keeps the snapshot (no overwrite). An in-flight guard prevents concurrent refreshes for the same cache key. The `features.diskCache: false` opt-out disables the warm read entirely.

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).

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.
