tab-setup

If `$ARGUMENTS` is `update`, pull the latest skill from its repo and re-install it: ```bash bash ~/.claude/skills/tab-setup/scripts/update.sh ``` Report whether it updated (and from/to which commit) or was already current. Note that changes take effect on the next Claude session. --- If `$ARGUMENTS` is `all`, run the bulk sync: ```bash bash ~/.claude/skills/tab-setup/scripts/sync-all.sh ``` Report the output exactly as returned (list of sessions with their assigned colors and TTYs). Renames inject automatically with a short delay — no further action needed. --- Otherwise, set up this session's tab: ```bash bash ~/.claude/skills/tab-setup/scripts/setup.sh "${CLAUDE_SESSION_ID}" $ARGUMENTS ``` The script output is one line: `color=<name> name=<tab-name>`. Report to the user: "Tab set up: **<color>** / **<name>**". Color applies immediately; `/color` and `/rename` fire automatically in ~4 seconds.
