Develop procedures locally, upload when ready

Iterate on a procedure in your own working directory and upload runs to the dashboard only when you choose, with no deploy step in the loop.

• Added tofupilot link to bind a working directory to a dashboard procedure, picking interactively or with --procedure for CI.
• Added --upload to tofupilot run so a linked local run syncs to the dashboard, while a plain run stays local for fast iteration.
• Added TOFUPILOT_PROCEDURE_ID to set the target in automation, and tofupilot unlink to remove a link.
