## Summary by cubic
Adds the `WebMCP` flag to the default local Chrome launch flags across
all SDKs so WebMCP works on Chromium versions newer than 157.
- Updates the WebMCP flag from
`--enable-features=WebMCPTesting,DevToolsWebMCPSupport` to
`--enable-features=WebMCP,WebMCPTesting,DevToolsWebMCPSupport` in
TypeScript, Python, and Go SDKs.
- Updates docs and test fixtures to match the new flag.
