Polish /resume and /compact command surfaces

[eduardtomas1]

Summary

• Rebuild the slash-command menu around T3Code's full-width floating command surface: 20px glass radius, grouped Built-in/Provider sections, neutral active rows, and scroll breathing room.
• Add real Arrow/Home/End navigation plus Enter/Tab selection while skipping unavailable commands.
• Move /resume from an embedded composer panel into the same floating surface, keeping the composer height stable and retaining search, session metadata, keyboard navigation, Escape, and outside-click dismissal.
• Restyle /compact progress and completion as a quiet work-log row with provider glyph, animated status dots, and explicit success/error state.
• Defer the command-surface CSS into a prewarmed UI chunk so the renderer stays inside its startup bundle budgets.

Reference implementation reviewed: T3Code command menu and scroll breathing-room follow-up.

Verification

• Focused renderer suite: 57 tests passed.
• Electron E2E: new command-surface geometry/keyboard/screenshot scenario passed.
• Existing model-chooser E2E passed with the active-option semantics.
• npm run check passed on Node 22.23.2: architecture, lint, typecheck, 3,698 tests (9 skipped), private-connect build, renderer build, and bundle budgets.
• Entry CSS remains within budget at 328.9 / 330.0 KiB.

Provider portable tests and packaging checks are not applicable: no provider protocol, dependency, packaging, or release behavior changed.

Safety and privacy

• Screenshots and fixtures contain synthetic project, chat, and provider-session data only.
• No credentials, private prompts, full local paths, logs, diagnostics, or user workspace data are included.
• Git and filesystem behavior is unchanged; unrelated user work remains untouched.
• No dependency, database migration, preload, IPC, or privileged-process changes.
