* ci(windows): validate host-absolute path schemas in the Windows lane
Windows hosts advertise their own absolute-path pattern (#7151). The lane
compiled it through advertisedDialect.test.ts but never validated a Windows
path against it. Run absoluteLocalPathSchema.test.ts there, select the lane
when the pattern's owner changes, and guard both schema checks in the lane.

* ci(windows): run live MCP schema validity in the Windows lane
toolSchemaValidity.test.ts compared the live advertisement with the
POSIX-generated .cache/mcp-tool-catalog.json, so it could not run where
the Windows lane skips artifact generation. Move the generated-catalog
cases into generatedToolCatalog.test.ts, share the reference walkers
through the advertised-schema fixture, and add the live-server file to
the curated Windows lane and its scope.
