 		Repoint tests and examples off removed deprecations 
Replaces FastMCP.as_proxy() helper calls with create_proxy(), rewrites the
mount() as_proxy=/prefix= kwarg tests to plain mount() (the params are gone),
and deletes deprecation-only tests for as_proxy() and remove_tool().

 		Remove deprecated FastMCP server methods for 4.0 
Removes deprecations that shipped replacements in 3.0:
- FastMCP.as_proxy() classmethod -> create_proxy()
- import_server() -> mount()
- mount(prefix=) -> namespace=
- mount(as_proxy=) -> now meaningless; mounts always invoke lifespan/middleware
- add_tool_transformation() -> add_transform(ToolTransform({...}))
- remove_tool_transformation() -> pure no-op that warned callers it had no
  effect; removed entirely
- FastMCP.remove_tool() -> mcp.local_provider.remove_tool()

Also drops the now-unused URI_PATTERN/re import and FastMCPDeprecationWarning
import. The _REMOVED_KWARGS TypeError shim is retained.

 		Remove no-op sse_read_timeout param from StreamableHttpTransport 
Tier 2 aggressive-window removal: the parameter was a deprecated no-op
on the streamable-HTTP transport (the SDK v2 client no longer supports
it). SSETransport still accepts sse_read_timeout.

 		Remove deprecated PromptToolMiddleware / ResourceToolMiddleware (3.1) 
Use the PromptsAsTools / ResourcesAsTools transforms instead. The
non-deprecated ToolInjectionMiddleware base class is retained.

 		Remove deprecated fastmcp.server.apps / server.app shims (3.2) 
Tier 2 aggressive-window removal: these shims were deprecated in 3.2,
a shorter deprecation window than the usual policy. Canonical imports
are fastmcp.apps / fastmcp.FastMCPApp.
