**Platform-Optimized Strategy:**
- **POSIX Systems** (Linux, macOS, FreeBSD): Use efficient kill(pid, 0)
- **Windows Only**: Use gopsutil.PidExists() when kill() unavailable
**Implementation:**
- Primary: kill(pid, 0) on all POSIX platforms (most efficient)
- Fallback: gopsutil only on Windows (where kill() doesn't exist)
- No unnecessary overhead - each platform uses optimal method
**Benefits:**
- Maximum Performance: POSIX systems use native kill(pid, 0)
- Windows Support: gopsutil provides Windows compatibility
- Minimal Dependencies: gopsutil only loaded when needed
- Platform Optimal: Each OS uses its most efficient method

* fix: optimize Go server CPU usage from 500%+ to efficient levels
Major performance improvements to resolve excessive CPU consumption:
**Critical Fixes:**
- Remove WebSocket busy loop that caused continuous CPU spinning
- Fix microsecond-level polling (100μs → 10ms) reducing 100x operations
- Replace ps subprocess calls with efficient kill(pid,0) syscalls
- Increase timer intervals (1s → 30s) for session status checks
**Optimizations:**
- Control FIFO polling: 100ms → 1s intervals
- Select timeout: 100ms → 1s to reduce unnecessary wakeups
- Smart status caching: skip checks for already-exited sessions
- Remove unused imports (os/exec, strconv)
**Impact:**
- Eliminates tight loops causing 10,000+ operations per second
- Reduces subprocess overhead from frequent ps command executions
- Changes from polling-based to efficient event-driven architecture
- Expected CPU usage reduction from 500%+ to levels comparable with Node.js version

* fix: prevent WebSocket channel close panic with sync.Once
- Add sync.Once to prevent double-closing of done channel
- Update handleTextMessage signature to accept close function
- Use closeOnceFunc for safe channel closure across goroutines
Fixes panic: 'close of closed channel' in WebSocket handler
* feat: add --do-not-allow-column-set flag to disable resizing for spawned sessions
**New Flag:**
- `--do-not-allow-column-set` (default: true) - Disables terminal resizing for spawned shells
- Only affects sessions created with `spawn_terminal=true`
- Detached sessions (command-line, API without spawn) always allow resizing
**Implementation:**
- Add `IsSpawned` field to session.Config and session.Info structs
- Track whether session was spawned in terminal vs detached
- Server checks flag + spawn status before allowing resize operations
- Returns descriptive error for blocked resize attempts
**Behavior:**
- Spawned sessions: Resize blocked when flag enabled (default)
- Detached sessions: Always allow resizing regardless of flag
- Existing sessions preserve their resize capabilities
**API Response for blocked resize:**
```json
{
"success": false,
"message": "Resizing is disabled for spawned sessions",
"error": "resize_disabled_for_spawned_sessions"
}
```

* 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.
