* Remove resource_prefix_format="protocol" support (fixes#2195)
Removes deprecated protocol format (prefix+resource://path) and keeps only
path format (resource://prefix/path). Since only one format remains:
- Removed resource_prefix_format from settings, FastMCP.__init__, and helpers
- Simplified add_resource_prefix, remove_resource_prefix, has_resource_prefix
- Removed MountedServer.resource_prefix_format field
- Deleted tests for protocol format
All resource prefixes now use path format exclusively.
* Clean up resource_prefix_format references
- Remove from test files
- Update documentation to remove protocol format section
- Move custom HTTP routes note to mounting section
- Remove resource_prefix_format from settings docs
* Use inline version note instead of badge for prefix format
* Remove obsolete test functions and update docs
- Delete test functions that no longer assert anything
- Remove proxy.mdx reference to deleted prefix format section
* Format error messages per ruff
- Add warning about performance impact in mounted servers section
- Explain that list_tools() operations are affected by slowest mounted server
- Note that HTTP-based servers can introduce 300-400ms latency vs 1-2ms for local
- Recommend import_server() for performance-critical applications
- Add performance considerations section to proxy documentation
- Reference composition documentation for alternatives

Prevents enable/disable operations on mirrored components (tools, resources, prompts retrieved from proxy servers). Users must create local copies with .copy() and add them to their server to modify them. Local components take precedence over mirrored ones.
