Replace string concatenation (+=) with array-based BufferAccumulator
in terminal buffer handling. This reduces garbage collection pressure
during high-throughput terminal streaming.
Changes:
- Add BufferAccumulator class with auto-trim on max size
- Convert _terminalBuffer and _textOutput to BufferAccumulator in session.ts
- Convert terminalBuffer to BufferAccumulator in respawn-controller.ts
- Remove manual trim logic (now handled by BufferAccumulator)

- Auto-compact now uses writeViaScreen with \r
- Auto-clear now uses writeViaScreen with \r
- Standardized respawn controller to use \r consistently
- Removed session name input from options modal (use right-click to rename)

Regular user input should go through PTY, only respawn controller
should use screen -X stuff. Added writeViaScreen() method for
programmatic input that needs reliable Enter key delivery.

When writing to an attached PTY connected to screen, the input doesn't
reliably reach Claude CLI. This fix uses `screen -X stuff` command to
send input directly to the screen session, bypassing the PTY attachment.
Research findings:
- Claude CLI uses Ink (React for CLI) for terminal UI
- Ink's parseKeypress detects \r as key.return (Enter)
- screen -X stuff with $'...' syntax reliably sends literal characters
Changes:
- Add ScreenManager.sendInput() using screen -X stuff
- Modify Session.write() to prefer screen -X stuff when available
- Keep \r as Enter key (what Ink expects for key.return)

Screen sessions require \n (line feed) for Enter key input, not \r
(carriage return). This fixes the issue where respawn prompts would
appear in the terminal but not be submitted.

Changed all command writes from \n (newline) to \r (carriage return).
PTY terminals expect \r for Enter key, \n only creates a new line
without executing the command.

The respawn controller was calling removeAllListeners('terminal')
which also removed the server's listener that streams output to
the browser. This made the console appear "blocked" when respawn
was enabled.
Now properly tracks and removes only its own listener.

- Fixed respawn controller immediately sending commands when Claude
becomes idle, which prevented users from typing. Now waits for
idleTimeoutMs (default 10s) before triggering the respawn cycle.
- Removed Directory field from Session Options modal for cleaner UI
- Compacted CLAUDE.md documentation for better readability

Kickstart Prompt:
- Remove Idle Timeout setting from respawn UI (uses 10s default)
- Add Kickstart Prompt field sent when /init doesn't trigger work
- New states: monitoring_init, sending_kickstart, waiting_kickstart
- Monitors 3s after /init to detect if Claude started working
Auto-Compact Context:
- Add auto-compact at 110k tokens (sends /compact with optional prompt)
- Preserves summarized context unlike /clear which wipes everything
- Optional focus prompt to guide what compact should preserve
- Blocks auto-clear while compacting to prevent conflicts
Also updates auto-clear default threshold from 100k to 140k tokens.

- Primary: Use '↵ send' indicator for immediate response when ready
- Fallback: Use timeout-based detection for prompt patterns
- Add working indicators: Synthesizing, Brewing, ✻, ✽
- Cleaner step completion handlers (checkUpdateComplete, etc.)
The hybrid approach responds immediately when Claude shows the
suggestion indicator, while still having timeout fallback for
reliability.

- Add '↵ send' as primary idle indicator (suggestion ready)
- Add 'Synthesizing', 'Brewing' to working patterns
- Add '✻', '✽' activity indicators to working patterns

- Change default idleTimeoutMs from 5s to 10s
- Use configured idle timeout for all step completion checks
- Ensures each step (update, /clear, /init) waits properly until idle

Implements an autonomous respawn loop that keeps Claude Code productive:
- Detects idle state by monitoring PTY for prompt character + timeout
- Sends configurable update prompt when idle (default: "update all the docs and CLAUDE.md")
- Executes /clear and /init to reset session
- Cycles automatically
New features:
- RespawnController class with state machine (watching → update → clear → init)
- REST API endpoints for respawn control (/api/sessions/:id/respawn/*)
- Web UI controls: toggle, prompt config, idle timeout settings
- SSE events for real-time respawn status updates
- Full CLAUDE.md template with Ralph Loop instructions
