Brings the #719 converter over from origin/aanchal/ingest and matches it to the current MCAP spec and committer: - Episode info uses the snake_case keys and annotation_source; `site` is gone, a label with no source is credited to the episode's lab. - Recordings carry end_effector. Aria's focal is chosen by rig_name, since lab now means who collected the data. - A delivery is steps.parquet, MP4s and meta.json, staged with commit.stage, under <staging>/mcap-<lab>/<vendor id>/ because vendor ids are only unique within a lab. A lab that can't name a folder is rejected. - Committer: Delivery.tasks is a list (a /task topic can hold several); meta-based loading takes an optional `tasks` list; `--source mcap-<lab>`; a delivery's annotation_type is kept. Aria, EVA and zarr deliveries load as before. - A re-export now removes only the lab's own labels, not ones credited to another annotation_source. Fixtures gain #719's options (vendor_recording_id now follows episode_id). SPEC.md documents the wrist frame, video outputs and staging path. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Replaces #719, which had drifted from the stack. Vendor MCAP episodes stage per lab under
mcap-<lab>/, with a task list per delivery and the Aria focal chosen by rig name.Tested: synthetic episodes on a local root, MANO off.
Not tested: real MCAP deliveries, MANO on this path, or training on its output.
