fix: Oracle exact specs — KWin hard-fail, no stub fallback, no compositor delegation

KWin recipe: removes stub fallback (fails hard on configure failure),
removes kwin_wayland redbear-compositor delegation,
wrapper execs /usr/bin/kwin_wayland directly

Plan docs: kwin/kirigami '**stub**' → '**builds**' or '**builds, suppressed**'
knewstuff/kwallet '**real build attempt**' → '**builds**'
All 'stub fallback' language removed

Matches Oracle round 12 exact specifications.
