What

• Pin oUF to 14.2.1 (c5ff6e4) and LibEditMode to 19 (b4816be) in scripts/fetch-libs.sh and scripts/setup-test-libs.sh
• Point THIRD_PARTY_NOTICES.md at the new upstream tags (upstream license files are unchanged)
• No addon code changes: the oUF and LibEditMode API our code uses is unchanged

Why

Both libraries were behind upstream. oUF 14.2.1 brings Forever fixes (the stagger guard, leader tags, the master looter events, secret-scrubbed raid GUIDs). LibEditMode 19 adds an X/Y coords box to the Edit Mode dialog.

Fixes #81

How to test

rm -rf UnitFrames/Libs UnitFrames_Media/Libs && scripts/setup-test-libs.sh
luajit tests/run.lua -j            # 1075 passed
scripts/install.sh                  # or --host arch

In game: /reload should show no Lua errors and the frames should appear. In Edit Mode, select a frame: the X/Y coords box shows above the dialog. Arrow keys nudge (Shift ×10, Alt ×0.1), and dragging, snapping and Reset position all still save per layout.

Worth a closer look

• The tests don't run the real libraries. tests/helpers.lua replaces oUF and LibEditMode with stubs, so the green run only shows our code is fine. The in-game check above is the real proof, and it's still pending.
• LibEditMode 19's coords box builds its labels with the global HEADER_COLON. Our Forever API snapshot doesn't list global strings. If the client lacks it, selecting a frame in Edit Mode throws an error.
• oUF's updateRaid now calls scrubsecretvalues (ClickGrid headers hit it). The call is in the Forever API snapshot.
• fetch-libs.sh and setup-test-libs.sh were checked to produce byte-identical lib trees.
