Closes#147. Changes default behavior of `uwf thread list` to show only
active threads (idle + running). Adds `--all` flag to opt into the
previous full-list behavior. Explicit `--status` still wins over `--all`.
- cmdThreadList gains a `showAll: boolean` parameter (default false)
- CLI registers `--all` option and passes it through
- Test suite includes new `default behavior (issue #147)` describe block
covering 9 scenarios; existing tests updated where they implicitly
relied on the old "show everything" behavior
- README, cli-reference, and usage-reference updated to document the
new default and the `--all` flag

Adds `uwf step ask <step-hash> -p <prompt>` for asking follow-up
questions to a completed step's agent without mutating thread state.
- Fork-by-default: creates and caches a fork session per step (cache
key `<stepHash>:ask`); subsequent asks reuse it.
- `--no-fork` fallback: spawns a fresh session with the step's detail
ref injected as context.
- `--agent` overrides the recorded agent; otherwise resolves from the
step's agent field via config alias.
- Updates `packages/cli/README.md` and `packages/util/src/usage-reference.ts`
so the new subcommand is discoverable via README and `uwf prompt usage`.
Fixes#146
