Summary

Strip a trailing .app from Spotlight display names before matching the Core Graphics window owner.

- "Find My.app" -> exact owner lookup fails
+ "Find My.app" -> "Find My" -> visible window found

Existing localized names and bundle-name fallbacks remain supported.

Evidence

• Before: regression test failed for Find My.app, Localiser.app, and Wo ist?.app; devices --json --no-log failed with no visible Find My.app window on macOS 26 despite a visible window.
  After: regression passes and the same device command returns JSON on that Mac using the unchanged helper.
• go test ./..., go vet ./..., make build, and git diff --check passed. Two independent source reviews found no issues.
• Clawpatch was unavailable locally; no Clawpatch report was generated.

Merge Danger

Door: two-way

Revert the normalization and regression cases.

Blast Radius: window-detection

Only the final .app suffix is removed; empty, null and bare bundle-name fallbacks remain unchanged.
