Charlie integration

Charlie support is beta.

tokenjuice install charlie inserts a marker-delimited instruction block into the current git/project root AGENTS.md. Charlie documents AGENTS.md as the durable repo-instruction surface that it loads by default, so tokenjuice uses that surface instead of claiming command-output interception.

tokenjuice install charlie
tokenjuice doctor charlie
tokenjuice uninstall charlie

By default, tokenjuice resolves the nearest git root before writing AGENTS.md. Set CHARLIE_PROJECT_DIR=/path/to/workspace to override the target workspace explicitly.

The installed block tells Charlie to use tokenjuice wrap -- <command> for terminal commands likely to produce long output, and to use tokenjuice wrap --raw -- <command> only when raw bytes are required.

Existing AGENTS.md content is backed up before install and preserved outside the managed tokenjuice block. Uninstall removes only the tokenjuice block.

doctor charlie reports ok when the AGENTS.md block exists, includes tokenjuice wrap guidance, includes the raw escape hatch, and does not suggest the full-output escape hatch.

This integration is guidance-only. Charlie can read project instructions, but those instructions do not replace terminal command output.
