CircleKit 0.3.63 · honest disabled actions

Fix a shared disabled-action visual bug: an empty SEND was correctly blocked,
but its arrow could remain bright. The shared circular action now makes disabled
state override implicit, semantic and custom icon tint. Enabled colours and
input/send behaviour are unchanged.

Disabled tap, tap-or-hold and continuous-press controls now also expose their
unavailable state to assistive clients. Explicit names and intentionally merged
child names are retained; disabled tap controls have no click actions.

Includes the product-owned category colours and DATA glyph from0.3.62. Same
Phone/Round atom, no Link-specific branch or new icon colour catalogue.

Existing focused regression RED1/2 before → GREEN2/2 after; tap-safety7/7,
text-input contract2/2, accessibility test compilation and both Showcase release
hosts compile. No new test file, emulator matrix or CI.
The actual Link empty-SEND screenshot is owned by its ongoing consumer release;
this publication does not claim that downstream installation.
