* fix: auto-start development servers in tmux instead of blocking

Replace blocking PreToolUse hook that used process.exit(2) with an auto-transform hook that:
- Detects development server commands
- Wraps them in tmux with directory-based session names
- Runs server detached so Claude Code is not blocked
- Provides confirmation message with log viewing instructions

Benefits:
- Development servers no longer block Claude Code execution
- Each project gets its own tmux session (allows multiple projects)
- Logs remain accessible via 'tmux capture-pane -t <session>'
- Non-blocking: if tmux unavailable, command still runs (graceful fallback)

Implementation:
- Created scripts/hooks/auto-tmux-dev.js with transform logic
- Updated hooks.json to reference the script instead of inline node command
- Applied same fix to cached plugin version (1.4.1) for immediate effect

* fix: resolve PR #344 code review issues in auto-tmux-dev.js

Critical fixes:
- Fix variable scope: declare 'input' before try block, not inside
- Fix shell injection: sanitize sessionName and escape cmd for shell
- Replace unused execFileSync import with spawnSync

Improvements:
- Add real Windows support using cmd /k window launcher
- Add tmux availability check with graceful fallback
- Update header comment to accurately describe platform support

Test coverage:
- Valid JSON input: transforms command for respective platform
- Invalid JSON: passes through raw data unchanged
- Unsupported tools: gracefully falls back to original command
- Shell metacharacters: sanitized in sessionName, escaped in cmd

* fix: correct cmd.exe escape sequence for double quotes on Windows

Use double-quote doubling ('""') instead of backslash-escape ('\\\") for cmd.exe syntax.
Backslash escaping is Unix convention and not recognized by cmd.exe. This fixes quoted
arguments in dev server commands on Windows (e.g., 'npm run dev --filter="my-app"').
