GET /runs/{id}/checkpoint duplicated what /state serves; the hidden
fabro parse command had no user; records, run_status, outcome, and
usage_rollup in fabro-workflow only re-exported fabro_types. The
importers now name fabro_types directly. format_cost keeps its two
callers (the pull request body and the CLI stage display) and moves to
fabro_types::usage; the usage rollup tests move beside the function in
fabro-types, with test_usage in its test support.

The legacy executor replayed a run from a checkpoint; Petri resumes a
run from its records instead, and the checkpoint timeline, rewind, fork
and retry were the operations that replay carried. The server dropped
their handlers with the executor; this removes the rest:
- the API spec's `/runs/{id}/retry`, `/rewind`, `/fork` and `/timeline`
paths with the `ForkRequest`, `ForkResponse`, `RewindRequest`,
`RewindResponse` and `TimelineEntryResponse` schemas, and the
generated TypeScript models;
- `fabro rewind` and `fabro fork` (with the checkpoint timeline printer
and the repo-origin check only they used), their reference pages and
the checkpoints guide's rewind and fork sections;
- `fabro-client`'s `rewind_run`, `fork_run` and `run_timeline`;
- the web app's Retry action on the run list and the run page.
`Run.retried_from` stays on the run type: a run that was retried before
the cutover would still name its source.
