ci: reuse Windows hook builds and shorten test setup and shutdown (#29439)

* ci: remove Windows build and persistence test overhead * ci: collect unit phase diagnostics during PR checks * test(ci): seed hook reuse fixture from the canonical prebuild The hook reuse regression first built into a missing private --output, so it always reached Cargo (74s warm on Windows). Build through the default output instead, which reuses a warm canonical prebuild, then copy its executable and fingerprint into the private fixture root. * fix(lint): clear inherited max-lines and broad object tab parameter after main merge Combine the duplicate shared/execution-host imports in runtime-host-services (301 -> 300 lines) and type the overlap test's tab mapper with the RuntimeMobileSessionClientTab owner type instead of object. * fix(ci): align inherited runtime and workflow contracts * test: establish changed runtime probe signatures deterministically * test: await asynchronous daemon profile cleanup * test: shut down owned daemons before deleting profiles * test: clean up oracle daemons during final app close * test: recognize verified Linux zombie exit during daemon teardown * fix: preserve folder SSH ownership when project groups conflict
