"""
Trellis StatusLine — project-level status display for Claude Code.
Reads Claude Code session JSON from stdin + Trellis task data from filesystem.
Outputs 1-2 lines:
With active task: [P1] Task title (status) + info line
Without task: info line only
Info line: model · ctx% · branch · duration · developer · tasks · rate limits
