Harden WinGet native fallback behavior

- restore the native WinGet API path to prefer packaged COM first and lower-trust COM second
- remove bundled in-proc COM from the native helper fallback chain so COM usage stays system-only
- skip unreachable WinGet catalogs during local package enumeration and fall back to the system winget CLI when native composite enumeration still fails
- avoid reconnecting WinGet COM while a local package query is still in flight so timeout retries can attach to the same work instead of restarting the slow enumeration
- clear stale malfunction UI state, re-expose the malfunction-detector toggle, and extend WinGet regression coverage around activation order, fallback behavior, source skipping, and retry handling
