feat(mcp): salvage selective tool loading with utility policies#1302
Conversation
…flag Add optional config keys under each mcp_servers entry: - tools.include: whitelist, only listed tools are registered - tools.exclude: blacklist, all tools except listed are registered - enabled: false: skip server entirely, no connection attempt Backward-compatible: no config keys = all tools registered as before. Tests: TestMCPSelectiveToolLoading (4 tests), 134 passed total.
Extend the salvaged MCP filtering work so utility tools are also governed by policy and server capabilities. Store the registered tool subset per server so rediscovery and status reporting stay accurate after filtering.
Expand the MCP feature docs with filtering and capability-aware registration details, add a practical 'Use MCP with Hermes' tutorial, add a config reference page, and wire the new docs into the sidebar and landing page.

This PR salvages the core selective-tool-loading work from #986 onto current main, then extends it to cover the utility-tool caveat and keep discovery/status semantics accurate.
