What

Follow-up to #5, driven by real-use feedback on the Settings > Models card and the missing Muse Wonder models.

• Live model catalog: the plugin now reads GET https://api.meta.ai/v1/models with the stored subscription key (same approach as openclaw-muse-code / hermes-muse-code) and declares the chat catalog on the meta route. Muse Wonder 1.0 / Wonder Full 1.0 (+ contributor) and future chat ids become selectable without a DSH catalog update; muse-image-*, muse-voice-*, and sam-* families are filtered; the five Muse Spark rows keep the shipped catalog's names, context window, output cap, and reasoning levels. A model list the user edited is never overwritten.
• Sign-in status: new exact GET /muse-code/status route (pending/authorized/failed/idle); the Settings card polls it and flips to Signed in without a reload.
• Card UI: rebuilt as a panel with title, coloured status dot, monospace device-code badge, primary/secondary actions, and wrapped text — the previous inline footer row squeezed the button and link into vertical one-word lines.
• /muse-login: after opening the browser it now waits for Meta's confirmation (bounded) and reports the final state instead of staying on "sign-in started" in the chat.
• Status polling timers are unref'ed so the chain cannot pin a Node process open (the client test file otherwise never exits).

Verification

• npm run typecheck, npm run build, 20 tests locally (host command/routes/model sync + client card harness), markdownlint 0 issues.
• Live smoke test against the real account catalog: 9 chat models synced, including the four Muse Wonder ids.
