The binary encoding was using 16-bit unsigned integers which failed when:
- Terminal has many rows (>65k)
- Cursor is above the viewport (negative relative position)
Changes:
- Upgrade to version 2 of the binary format
- Use 32-bit integers for dimensions and positions
- Use signed integers for viewport/cursor positions
- Update header size from 16 to 32 bytes
- Update documentation to reflect new format
This fixes the issue where cursorY could be negative when the cursor
is above the visible viewport (e.g., cursorY=0, viewportY=46 results
in relative cursorY=-46).

Replace terminal.ts in session-card with new buffer-based component that:
- Fetches terminal buffer snapshots via JSON API
- Polls every second only when content changes (checks lastModified)
- Automatically calculates lines needed based on container height
- Reuses terminal rendering styles and logic
Changes:
- Create terminal-renderer.ts with shared rendering logic for both components
- Add vibe-terminal-buffer component that works with buffer API
- Update session-card to use vibe-terminal-buffer instead of vibe-terminal
- Add terminal-line CSS for proper styling
- Fix color handling in terminal-manager (-1 means default color)
- Add debug logging to help diagnose rendering issues
The new approach is more efficient - no cast file parsing, just direct
buffer snapshots from the server.

* Fix SSE streaming performance with byte-based approach
Addresses @badlogic's review feedback to prevent performance issues
with line-based file reading in processNewContent().
## Changes Made
### Performance Fix
- **Byte-based seeking**: Replace line counting with file position tracking
- **Efficient reads**: Only read new content since last position using file.Seek()
- **Memory optimization**: Avoid reading entire file on each update
- **Incomplete line handling**: Properly handle partial lines at file end
### Technical Details
- Changed lastLineCount *int → seenBytes *int64
- Use file.Seek(seenBytes, 0) to jump to last read position
- Read only new content with currentSize - seenBytes
- Handle incomplete lines by adjusting seek position
- Maintains same functionality with better performance
### Benefits
- **Scalability**: No longer reads entire file for each update
- **Performance**: O(new_content) instead of O(total_content)
- **Memory**: Constant memory usage regardless of file size
- **Reliability**: Handles concurrent writes and partial lines correctly
This prevents the SSE streaming from exploding in our faces as @badlogic
warned, especially for long-running sessions with large output files.

* Optimize streaming performance to reduce 1+ second delays
Implements multiple optimizations to address user-reported 1+ second delay
between typing and stream rendering:
## PTY Reading Optimizations
- **Reduced sleep times**: 100ms → 1ms for EOF checks
- **Faster polling**: 10ms → 1ms for zero-byte reads
- **FIFO optimization**: 1s → 100ms for stdin EOF polling
## UTF-8 Buffering Improvements
- **Timeout-based flushing**: 5ms timer for incomplete UTF-8 sequences
- **Real-time streaming**: Don't wait for complete sequences in interactive mode
- **Smart buffering**: Balance correctness with responsiveness
## File I/O Optimizations
- **Immediate sync**: Call file.Sync() after each write for instant fsnotify
- **Reduced SSE timeout**: 1s → 100ms for session alive checks
- **Better responsiveness**: Ensure file changes trigger immediately
## Technical Changes
- Added StreamWriter.scheduleFlush() with 5ms timeout
- Enhanced writeEvent() with conditional file syncing
- Optimized PTY read/write loop timing
- Improved SSE streaming frequency
These changes target the main bottlenecks identified in the
PTY → file → fsnotify → SSE → browser pipeline.

* Fix critical performance issues causing resource leaks and CPU burns
Performance optimizations based on code review feedback:
1. **Fix SSE goroutine leaks**:
- Added client disconnect detection to SSE streams
- Propagate write errors to detect when clients close connections
- Prevents memory leaks from abandoned streaming goroutines
2. **Fix PTY busy-loop CPU burn**:
- Increased sleep from 1ms to 10ms in idle scenarios
- Reduces CPU wake-ups from 1000/s to 100/s (10x improvement)
- Significantly reduces CPU usage when PTY is idle
3. **Multi-stream disconnect detection**:
- Added error checking to multi-stream write operations
- Prevents goroutine leaks in multi-session streaming
These fixes address the "thing of the things" - performance\!

- Maintains backward compatibility with existing sessionId field
- Go server already supported both input formats (cmdline/command, cwd/workingDir)
This achieves protocol compatibility between Go and Rust implementations.
