This PR adds a `fabro wait` subcommand that blocks until a workflow run
reaches a terminal state and exits with a code reflecting the outcome —
analogous to `docker wait`. The command accepts a run ID prefix or
workflow name, polls `status.json` at a configurable interval
(defaulting to 1 second), and exits 0 on success or 1 on failure/dead.
An optional `--timeout` flag causes the command to bail with an error
message if the deadline is exceeded before the run completes.
The implementation reuses existing infrastructure throughout:
`resolve_run()` for run ID/name resolution, `RunStatusRecord::load()`
and `RunStatus::is_terminal()` for polling, `Conclusion::load()` for
retrieving duration and cost after completion, and `Styles` for colored
terminal output. Human-readable status is written to stderr (preserving
stdout for data), while `--json` mode writes structured conclusion data
to stdout. Missing status files are treated as `Dead` to handle orphaned
runs gracefully. No new dependencies were required.
The change is registered in all three necessary locations:
`commands/mod.rs`, the `Command` enum in `main.rs`, the command name
mapping, and the dispatch match arm. Unit tests cover JSON output across
all terminal states (with and without conclusion data), the
human-readable output path, immediate-terminal poll behavior, and the
missing-file fallback to `Dead`.
