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
Re-runs the head step's agent with a supplementary prompt and replaces
the head step (rewires new step's prev to old head's prev) instead of
appending. Skips moderator re-route — the role of the head step is
reused.
Fixes#144
- `uwf prompt usage` now outputs only the usage skill (was three combined)
- `uwf prompt bootstrap` replaces `setup` with framework-agnostic instructions
- Remove `usage-reference` and `setup` subcommands
- Remove `generateBootstrapReference` from util (moved to cli)
Fixes#99
小橘 🍊（NEKO Team）
Remove migrateStorageIfNeeded() which created symlinks from
~/.uncaged/workflow → ~/.uwf and ~/.uncaged/json-cas → ~/.ocas.
This was temporary migration support. Users who still have old paths
can run a one-time copy manually.
Zero 'uncaged' references remain in active codebase.
