Allow users to enable/disable specific MCP tools through the `tools`
field in cclsp.json. Tools not listed default to enabled; set to
`false` to disable.
Example config:
```json
{
"tools": {
"rename_symbol": true,
"find_references": true,
"find_definition": false,
"get_diagnostics": false
},
"servers": [...]
}
```
This addresses the need to reduce context window usage by exposing
only the tools actually needed for a workflow.

Summary
This PR adds the ability to enable/disable specific MCP tools through the
toolsfield incclsp.json.Problem: Currently, all 12 tools are always exposed, which can clutter the context window when only a few tools are needed.
Solution: Allow users to configure which tools are enabled via config:
{ "tools": { "rename_symbol": true, "find_references": true, "find_definition": false, "get_diagnostics": false, "get_hover": false, "find_workspace_symbols": false, "find_implementation": false, "prepare_call_hierarchy": false, "get_incoming_calls": false, "get_outgoing_calls": false, "rename_symbol_strict": false, "restart_server": false }, "servers": [...] }falseare not exposed viaListToolsChanges
