Petri 639ce3e added `ControlService::interrupt_firing` and the `LiveTurns`
capability a host installs beside the pause hooks. Fabro now drives it:
`RunControls::interrupt(stage, text)` resolves its stage the way a steer
does (a label, a node name, or the run's one live agent stage) and stops
that stage's current model turn, keeping the session; the text, when
given, is the stage's next input. `engine::run` installs the live-turn set
as a runtime capability, so without it no interrupt could ever land.
The worker maps `run.interrupt` and `run.interrupt_then_steer`, both of
which now carry an optional `stage`, to that call. The control bus is
one-way, so a refusal is recorded the way a refused steer is: a
`run.notice` on the run's stream whose code says why (`no_live_turn` when
Petri refuses a stage with no turn in flight, `no_such_stage`,
`interrupt_refused`).
The server's `POST /runs/{id}/interrupt` and `POST /runs/{id}/steer` with
`interrupt=true` forward the control and answer 202, replacing the 501
`interrupt_unsupported` stub. The interrupt endpoint takes an optional
body (`stage`, `text`), refuses a finished run with 409
`run_not_interruptible`, and forwards an interrupt of a blocked run, since
an agent stage may be running a turn beside the question and the worker
judges each stage itself. `fabro events --pretty` prints the delivered
interrupt and the stage's `attractor.turn.interrupted` report.
Verified on the twin: `fabro steer --interrupt` during a long tool call
ends the turn, the text is the agent's next request, and the stream
carries the `$interrupt` record and the interrupted-turn report; an
interrupt of a gate stage is refused with `no_live_turn` and the gate's
question is untouched.

`SteerRunRequest` takes an optional `stage`: the label the projection
shows (`node@visit`, or `node/e<execution>@visit` when two executions
share one) or the node's name. The server passes it on the worker control
message; the worker's `RunControls` resolves a label to the live agent
firing and steers that firing, and a node name through Petri's own
live-stage index. Unnamed, the one-live-agent rule stays, and the refusal
now names the live stages by their labels. `fabro steer --stage` sets it.
A controls scenario runs two agent stages side by side, sees the unnamed
steer refused with both named, and steers each apart, one over the API
and one through the flag.

The review question sentence was written in four places and the URL
safety rules in three. Collapse each to one definition.
- Add `ReviewTarget::question_text_with_link` as the single definition of
the question wording. `question_text()` and the Slack header both use
it, so a wording change is now one edit.
- Delete `ReviewTargetKind::noun()`. The enum already derives
`strum::Display` with the same snake_case output.
- Share one `review_target_line` helper between the console interviewer
and the CLI attach client, which held a byte-identical copy. Print only
the URL: `question.text` already carries the label and the noun.
- Trim the web-side check to the URL scheme, host, and credentials, which
are what a raw `href` can act on. Label length and control characters
cannot affect the DOM and stay server-side.
- Split validation from presentation in the web UI. `safeReviewTarget`
returns the target or null, and each caller picks its own fallback, so
an unsafe target now falls back to the same Markdown rendering as a
question with no target.
- Derive the resource noun from `kind` in the web UI instead of
hardcoding "document".
- Use `ReviewTargetKind.DOCUMENT` and the shared `isRecord` guard when
parsing events, instead of a raw string and a hand-rolled object check
that accepted arrays.
- Drop `deny_unknown_fields` from the wire struct. The OpenAPI schema
leaves `additionalProperties` permissive, so an added field would
otherwise make persisted events unreadable.
- Import `ReviewTarget` by name, and stop naming Slack in a fabro-types
error message.
- Document that `review_target=true` replaces the gate's `label`.
