KittyImage now uses fs.writeSync(process.stdout.fd) for all Kitty protocol
sequences (transmit, placement, deletion) instead of Ink's stdout.write,
preventing conflicts with Ink's screen refresh cycle inside Codev's TUI.
Also adds 'term.includes("ghostty")' to detectTerminalCaps() to recognize
Kitty support when running inside tmux with TERM=xterm-ghostty.

fix: use env-var terminal detection to avoid stdin conflicts in TUI
Replace InkPictureProvider's ANSI escape queryTerminal() with
environment-variable-based detection (TERM, TERM_PROGRAM, KITTY_WINDOW_ID)
to reliably detect Kitty/Sixel/iTerm2 protocol support without hijacking
stdin, which conflicted with Ink's TUI input management.
InkPictureProvider now skips queryTerminal entirely when terminalInfo
overrides are provided, preventing garbled ANSI response leakage into
the input bar.
