Extract fabro resume subcommand (#137)
This PR extracts the `fabro resume` subcommand from `fabro run`,
replacing the `--resume` and `--run-branch` flags with a dedicated, more
ergonomic interface. Users can now run `fabro resume <RUN_ID>` instead
of constructing `fabro run --run-branch fabro/run/<RUN_ID>` manually,
and the command also accepts run ID prefixes (matching the pattern
established by `fabro rewind` and `fabro fork`). Checkpoint-file-based
resumption is also supported via `fabro resume --checkpoint
path/to/checkpoint.json --workflow workflow.fabro`.

The implementation moves the ~315-line `run_from_branch()` function out
of `run.rs` and into a new `commands/resume.rs` module, splitting it
into two preparation paths (`prepare_from_checkpoint` and
`prepare_from_branch`) that converge on a shared `run_resumed()` tail.
Several previously private helpers in `run.rs` are widened to
`pub(crate)` to allow sharing: `local_sandbox_with_callback`,
`resolve_ssh_config`, `resolve_ssh_clone_params`,
`resolve_preserve_sandbox`, `generate_retro`, `write_finalize_commit`,
`print_final_output`, `print_assets`, and the new `default_run_dir`
helper extracted from duplicated inline logic. The `RunArgs` struct
loses its `resume` and `run_branch` fields along with their
`conflicts_with` annotations, and `RunSpec` drops the corresponding
fields with `#[serde(default)]` for backward compatibility.

Documentation across `docs/reference/cli.mdx`,
`docs/execution/checkpoints.mdx`, and
`docs/core-concepts/how-fabro-works.mdx` is updated to reflect the new
interface, and the `rewind`/`fork` commands now hint `fabro resume
<short-prefix>` instead of the full branch name.

44731e0926 Rename arc setup to arc install for clarity
The one-time environment setup command (LLMs, certs, GitHub) is now
`arc install`, freeing up naming space for a future `arc init` command
for per-project initialization.
