…s (#17098)

Two amplifying optimizations to per-turn overhead in the gateway:

1. get_tool_definitions() memoization (model_tools.py)
   Keyed on (frozenset(enabled), frozenset(disabled),
   registry._generation, config.yaml mtime+size). Only active when
   quiet_mode=True (which is every hot-path caller — gateway,
   AIAgent.__init__); quiet_mode=False keeps the existing print side
   effects. Cached path returns a shallow-copy list sharing read-only
   schema dicts.

   Measured: 7.5 ms → 0.01 ms per call (~750× speedup). Gateway
   constructs fresh AIAgent per message, so this saves ~7 ms/turn before
   any LLM work.

2. check_fn() TTL cache (tools/registry.py)
   check_fn callables like check_terminal_requirements probe external
   state (Docker daemon, Modal SDK, playwright binary). For a long-lived
   process, hitting them on every get_definitions() pass was pure waste
   — external state changes on human timescales. 30 s TTL so env-var
   flips (hermes tools enable X) propagate within a turn or two without
   explicit invalidation.

   Measured: first call 7.5ms → 1.6ms (check_fn probes now dominate);
   subsequent calls ~0.01ms via the upstream memoization.

Invalidation surface:
- registry._generation bumps on register/deregister/register_toolset_alias,
  invalidating the memoized definitions automatically.
- config.yaml mtime in the cache key captures user-visible config edits
  affecting dynamic schemas (execute_code mode, discord allowlist).
- invalidate_check_fn_cache() exposed for explicit flushes (e.g. after
  hermes tools enable/disable).
- tests/conftest.py autouse fixture clears both caches before every test
  so env-var monkeypatches don't see stale results.

Also fixes a regression from PR #17046 that I missed:
- tools/web_tools.py — Firecrawl was removed from module scope by the
  lazy import, breaking 8 tests that patch 'tools.web_tools.Firecrawl'.
  Applied the same _FirecrawlProxy pattern used in auxiliary_client/
  run_agent for OpenAI (module-level proxy that looks like the class
  but imports the SDK on first call/isinstance; patch() replaces the
  attribute as usual).

Verified:
- 49/49 tests/tools/test_web_tools_config.py pass (was 8 failing on main)
- 68/68 tests/tools/test_homeassistant_tool.py pass (was 1 failing in
  the full suite due to check_fn TTL cross-test pollution; fixed by
  the autouse fixture)
- 3887/3895 tests/tools/ (8 pre-existing fails: 2 delegate, 1 mcp
  dynamic discovery, 5 mcp structured content — all confirmed on main)
- 2973/2976 tests/agent/ + tests/run_agent/ (3 pre-existing fails)
- 868/868 tests/run_agent/ (excluding test_run_agent.py which has
  pre-existing suite-level issues)
- Live smoke: 2 turns + /model switch + tool calls, zero errors in
  agent.log session window.
