v0.12.0 — Rename paired devices

Paired devices can now be renamed from Setup without unpairing them or changing their credentials or session expiry. Labels persist across container recreations; clearing a label restores the original device name.

The rename form uses a compact, centred dialog on desktop and a short bottom sheet on phones. It includes device context, a live character counter, keyboard controls, comfortable touch targets, and inline errors that preserve your input. Save is enabled only when the label changes, and pending saves cannot be submitted twice.

Includes T3 Code 0.0.45 and the reliable agent updates introduced in v0.11.1.

Images for Linux amd64 and arm64:

• Browser: ghcr.io/dizys/t3code-docker:0.12.0 or :0.12.0-browser
• Core: ghcr.io/dizys/t3code-docker:0.12.0-core
• The latest, browser, full, core, and slim tags point to this release.

Each platform image passed its smoke tests; both amd64 variants passed the real agent lifecycle tests before publication. Release manifests were verified against those tested image digests.
