tg — Tangled CLI skill

Before any tg command, run the bootstrap

bash skills/tg/auth.sh

The script self-locates the vendored bin/tg relative to its own path, so it doesn't matter what the current working directory is — but the path above assumes the project root is cwd, which is the usual claude agent default. If you're elsewhere, use the absolute path.

auth.sh:

1. Symlinks the vendored bin/tg onto $PATH if not already there.
2. Maps BSKY_HANDLE/BSKY_APP_PASSWORD to the ATPROTO_* names that tg auth login reads.
3. Runs tg auth login only if there's no live session.
