8248d465df feat(electrobun): redesign AgentPane to match Claude Code VSCode extension 
Based on official Claude Code v2.1.79 webview CSS analysis:
- Timeline pattern: 7px dots + 1px vertical line, 30px content indent
- User messages: left-aligned inline blocks (not right-aligned bubbles)
- Tool calls: flat bordered grid boxes with 60px mask-fade clipping
- Floating input: absolute bottom:16px, crust bg, 8px radius, shadow
- ChatInput.svelte extracted: auto-resize textarea, peach send button
  (26×26, 5px radius), focus ring with color-mix peach 12%
- Footer strip: model name + attach button + divider + send button
- Status strip: compact top bar with dot + status + model + cost
- 150px gradient fade at message area bottom
- fadeIn 0.3s animation on new messages

621e1c5c8c fix(agor-pty): implement real PTY resize (TIOCSWINSZ via portable-pty) 
Was only updating cached dimensions without calling PTY resize.
Shell thought terminal was wrong size → double prompts, escape code leaks.

- Session stores master PTY handle (Arc<Mutex<Box<dyn MasterPty>>>)
- resize() calls master.resize(PtySize) → issues TIOCSWINSZ
- Reader task no longer owns master handle (uses cloned reader only)

4676fc2c94 feat(electrobun): wire PTY daemon into terminal tabs via Electrobun RPC 
- Bun process connects to agor-ptyd via PtyClient (5 retries, exponential backoff)
- RPC bridge: 5 request handlers (create/write/resize/unsubscribe/close)
- Daemon output forwarded to WebView as pty.output messages (base64 passthrough)
- Terminal.svelte: real PTY sessions via RPC instead of echo mode
- Shared RPC schema at src/shared/pty-rpc-schema.ts
- Fixed pty-client.ts protocol: base64 string for data (was number array)
- TerminalTabs passes sessionId to Terminal component

4b5583430d feat: agor-pty crate — standalone PTY multiplexer daemon (Phase 1 WIP) 
New crate at agor-pty/ (standalone, not in workspace — portable to Tauri/Electrobun):
- Rust daemon (agor-ptyd) with Unix socket IPC, JSON-framed protocol
- PTY session lifecycle: create, resize, write, close, output fanout
- 256-bit token auth, multi-client support, session persistence
- TypeScript IPC client at clients/ts/pty-client.ts (Bun + Node.js)
- Protocol: 9 client messages, 7 daemon messages
- Based on tribunal ruling (78% confidence, 4 rounds, 55 objections)

WIP: Rust implementation in progress (protocol.rs + auth.rs done)

b79fbf688e perf(electrobun): JS blink replaces CSS animation, 1.13% CPU (was 6.5%) 
JS setInterval(500ms) toggles .blink-off class instead of CSS @keyframes.
WebKitGTK handles discrete class toggle efficiently (single repaint per toggle).
0.7% idle + 0.43% blink overhead = 1.13% total.

Comparison:
- CSS @keyframes: 6.5% (continuous compositor animation)
- JS class toggle: 1.13% (2 repaints/sec)
- No animation: 0.7% (baseline)
- Tauri (CSS): ~0% (browser compositor optimized)
- GPUI (custom Element): 2.17%

6f0f276400 perf(ui-gpui): flatten hierarchy + SharedBlink (Arc<AtomicBool>) 
- Eliminated ProjectGrid entity level: Workspace renders ProjectBoxes directly
  (3 dispatch tree levels: Workspace → ProjectBox → inline divs)
- Replaced Entity<BlinkState> + Entity<StatusDotView> with SharedBlink
  (Arc<AtomicBool> toggled by background timer, read atomically in render)
- Timer calls cx.notify() directly on ProjectBox (no intermediate entities)
- CPU: 2.93% (unchanged from 3.07% — confirms cost is ProjectBox::render()
  overhead, not hierarchy depth or entity count)
- Each blink frame: ~15ms total (render + layout + prepaint + paint + GPU submit)
- Zed comparison: ~5ms per blink frame (EditorElement is custom Element, not div tree)

ddec12db3f perf(ui-gpui): simplify ProjectBox render, confirm 3% is hierarchy depth cost 
Each blink = ~15ms CPU (1-2 ticks/500ms). Cost is Entity dispatch tree
walk through 4 levels (Workspace→ProjectGrid→ProjectBox→StatusDotView),
not div count. Zed achieves ~5ms with 3 levels. To match: flatten hierarchy.

f797a676f4 perf(ui-gpui): isolate StatusDotView entity, document 3% CPU floor 
Root cause analysis:
- 0% baseline: calloop 60Hz polling has zero measurable CPU cost
- 3% is entirely from ProjectBox::render() rebuilding ~30 header divs
  × 2 boxes × 2/sec = 120 div constructions/sec
- AgentPane + TerminalView cached (into_cached_flex) = 0% contribution
- mark_view_dirty() walks ancestors unconditionally in GPUI 0.2.2
  → StatusDotView isolation doesn't prevent parent re-render
- Fragment shaders not exposed (paint_quad accepts static color only)
- GPUI AnimationElement uses request_animation_frame = 79% CPU (vsync)

StatusDotView pattern is architecturally correct for future GPUI versions
that may implement per-view dirty isolation.

727c7d2e06 perf(ui-gpui): revert AnimationElement (79% CPU), document shader limitation 
GPUI's AnimationElement uses request_animation_frame() internally which runs
at vsync (60fps) causing 79% CPU. Fragment shaders not exposed through GPUI's
Scene API (paint_quad only accepts static color, no time uniform).

Reverted to BlinkState timer pattern (3% CPU, 2 renders/sec).
This is the same approach Zed uses for cursor blink.

Tested approaches and results:
- AnimationElement + pulsating_between: 79% CPU (vsync loop)
- BlinkState + timer(500ms) + cx.notify(): 3% CPU (correct)
- Custom Element + paint_quad: no shader access
- CSS animation (Blitz): 30% CPU (full repaint loop)

73cfdf6752 perf(ui-gpui): cache SharedStrings, remove diagnostics, zero alloc per render frame
