Teknium 0cfc1f88a3 fix: add MCP tool name collision protection (#3077) ...

- Registry now warns when a tool name is overwritten by a different
  toolset (silent dict overwrite was the previous behavior)
- MCP tool registration checks for collisions with non-MCP (built-in)
  tools before registering. If an MCP tool's prefixed name matches an
  existing built-in, the MCP tool is skipped and a warning is logged.
  MCP-to-MCP collisions are allowed (last server wins).
- Both regular MCP tools and utility tools (resources/prompts) are
  guarded.
- Adds 5 tests covering: registry overwrite warning, same-toolset
  re-registration silence, built-in collision skip, normal registration,
  and MCP-to-MCP collision pass-through.

Reported by k_sze (KONG) — MiniMax MCP server's web_search tool could
theoretically shadow Hermes's built-in web_search if prefixing failed.
