Extract business logic from MCP tool handlers into 15 Action classes
(Plan 5, Session 5, Phase 3, Task 2) following the Brain pattern.
MCP tools become thin wrappers calling Action::run(). Add framework-level
REST controllers and routes as sensible defaults for consumers.

Replace hardcoded cache key in ForAgentsController with a config-based
key (`mcp.cache.for_agents_key`) and configurable TTL
(`mcp.cache.for_agents_ttl`). This prevents collisions with other modules
or packages that might use the same flat cache key.
- Add `cacheKey()` method on ForAgentsController, reads from config
- Add `cache` section to config.php with default key and TTL
- Dynamic Cache-Control max-age now follows the configured TTL
- Add ForAgentsControllerTest covering key customisation,
cache storage, invalidation, TTL, and response structure
