Fix embedded terminal for Claude Code: PTY env, DEC 2026, xterm.js window queriesHEADv0.2.4main

- Add missing PTY environment variables (TERM, COLORTERM, LANG, TERM_PROGRAM)
- Strip DEC 2026 synchronized output sequences that cause xterm.js to buffer
  indefinitely when begin/end markers are split across PTY chunks
- Enable xterm.js windowOptions for terminal pixel/char size queries that
  Claude Code sends to determine rendering capabilities
- Launch Claude tab via login shell for full PATH inheritance
