feat(tui): render quota progress bar under the prompt

[zuoqiumama]

Summary

Renders a compact quota progress bar directly under the TUI prompt. The bar shows the single-window quota entry (preferring the 5h window), remaining percent, and a reset countdown, with a subtle animation while the session is running. It replaces the compact status line under the prompt and falls back to that line when disabled.

This was originally prototyped locally by hand-editing the installed plugin bundle; this PR ports the feature to the source tree and adds the missing \ uiPromptBar\ config plumbing.

Linked Issue

No issue exists yet; this PR is opened alongside the feature (issue-first per CONTRIBUTING is fine to open in parallel). Scope: new opt-in TUI surface, default \ rue, configurable via \quotaToast.tuiPromptBar.enabled.

What changed

• \src/lib/types.ts\ / \src/lib/config.ts: new \ uiPromptBar\ config key (default { enabled: true }) with patch extraction, apply, and setting-source tracking. Also deep-clones the new nested key in \cloneConfig\ to avoid mutating \DEFAULT_CONFIG.
• \src/lib/tui-panel-state.ts: \PromptBarState\ / \PromptBarEntry\ surface types.
• \src/lib/tui-runtime.ts: \pickPromptBarEntry\ (prefers the 5h window entry, falls back to the lowest remaining percent), \�uildPromptBarFromData, and wiring through \loadTuiSessionQuotaSurfaces\ /
  esolveTuiSurfaceRegistration.
• \src/tui.tsx: \PromptQuotaHint\ / \SessionQuotaPromptBar\ render the 12-cell bar (label + percent + reset countdown, animated while running). The \session_prompt\ slot prefers the bar when \promptBar.enabled, otherwise keeps the existing compact status line behavior; the fallback registration stays conservative.
• Tests updated in \ ests/tui-runtime.test.ts, \ ests/tui-smoke.test.ts, \ ests/tui-startup-runtime-resolution.test.ts.
• Docs: \docs/readme/configuration.md, \docs/readme/manual-install.md.

OpenCode Validation

• Current production released OpenCode version tested: 1.18.15 (TUI)
• Why this version is relevant to the fix: the feature targets the TUI plugin surface (\session_prompt\ slot, \�pi.state.session.status), which is stable across recent releases.

Quality Checklist

• I ran \pnpm run typecheck\
• I ran \pnpm run build\
• I ran \pnpm test\ (Windows: remaining failures are pre-existing environment issues, verified unchanged with and without this PR)
• This change is focused and avoids unrelated behavior changes
• I updated or added tests when behavior changed
• I updated docs when user-facing workflow, command, or config behavior changed
• For provider changes, I followed Provider Changes, or this does not apply (no provider changes)

[slkiser]

Thanks for building the prompt quota bar. I pushed a maintainer follow-up and synced the branch with current main.

The original shared-session design stays intact. The follow-up:

• makes the bar opt-in
• places it below the prompt so it cannot cover input
• shows unavailable when a completed quota request has no usable window
• prefers the five-hour window, then uses the lowest valid quota value
• animates only while a session is busy or retrying
• adds config, selection, fallback, layout, and lifecycle tests
• updates the README and configuration guide

Maintainer commits:

• 4bb4b86 — make the prompt quota bar opt-in and harden its behavior
• 78dba35 — sync the branch with current main

Local checks passed: 142 focused tests, typecheck, build, 1,865 full tests, four-surface parity, package checks, and full pnpm verify.

GitHub CI also passed, including the Node 22 and Node 24 package smoke tests. This is ready to merge.
