review: holder-only generate events, wrapper states and breakpoints in the bake

A generate event may open a session only from the page that holds the
target's lease, or held it last while its lease lapsed or its page went
away; a page that never claimed, or a lapsed holder once a rescuer has
claimed, is refused as before. The pending target remembers its last
holder for that.

The bake now lands a state written on the wrapper (`:scope:hover > .x`,
`:scope[open] > .x`) on the element that takes the wrapper's place, and
rewrites Astro's prefixed rules wherever they sit, `@media` and
`@supports` blocks at the top level included, instead of dropping the
variant's breakpoints.

A `generate` event on `POST /events` may carry `agentTarget: {targetId, result}`: once the event is accepted, the server resolves that pending target with `result` (the envelope is stripped before journaling and never reaches the poller), so a page that dies between Go and its result cannot leave the request pending for a second Go elsewhere; whichever of the event and the result post lands first answers. An accepted generate event carrying the envelope is journaled and queued with `origin: "agent"`, and `live-poll` renders that event's `_instructions` as the fast path (identity from the event's `element.computedStyles` / `cssCustomProperties` / `parentContext`, the action's three dimensions, no parameter knobs unless the prompt asks, one edit, reply done) instead of the interactive planning pointer and the action-reference read. The envelope also carries `clientId`: a generate event naming a target that another page now holds (a live lease, this page's having lapsed while it captured) or that was already answered, with a different session or with none (a timeout or a failure verdict the CLI has reported), or that the helper neither holds nor remembers (never issued by it, or evicted from its bounded record of answered targets), is refused with 409 `{"error":"agent_target_already_served", targetId, sessionId?}` and journals nothing, and the overlay drops that local session; the answering session's own event is welcome. |

| `POST /live-bar` | 401 / 400 Invalid JSON | `hidden` (boolean) required else 400 `{"error":"live_bar: hidden must be a boolean"}`. Sets the helper-wide bar preference; on a change broadcasts `{type:'live_bar', hidden}` to every SSE client. `GET /status` and the SSE `connected` frame carry it as `hideLiveBar`. Answers `{ok:true, hidden}`. |
| `POST /agent-target-claim` | 401 / 400 Invalid JSON | `targetId` and `clientId` (non-empty strings) required else 400 `{"error":"agent_target_claim: missing targetId or clientId"}`. Roll call plus a first-wins lease, so exactly one overlay acts on a broadcast target. Unknown or resolved target → `{ok:true, granted:false, pending:false}` (ends a rescuer's retry loop). `eligible !== true` → record `{state, reason, result?}` under `clientId` (replacing an earlier report; `result` is the overlay's resolution verdict when `reason` is `no_match`, i.e. its page cannot resolve the selector), release the lease if this client holds it, answer `{ok:true, granted:false, pending}` (`pending` false once the request resolved, so a declining overlay knows whether to keep watching for a change of its word), then complete the roll call when no owner holds the lease and reports ≥ connected overlays. Verdict precedence: a report whose `reason` is not `no_match` (a tab that could serve later) → `{ok:false, error:'busy', state, reason}` at once; when every report is `no_match` the roll call stays open for `IMPECCABLE_AGENT_TARGET_RESOLVE_GRACE_MS` (default 3000) after each overlay's first such report (a late reporter extends the grace by the full window; a page whose element mounts late keeps re-checking while its decline answers `pending:true`, an eligible claim drops its stale report, and the overlay declines rather than posting a result when the element is gone after its claim), then answers the first report's `result` (e.g. `no_match` with `rawMatchCount`, `invalid_selector`); the timeout uses the same precedence when any report exists. `eligible === true` → drop this client's earlier report; `granted` when no owner, the same owner (renew), or the lease lapsed (`IMPECCABLE_AGENT_TARGET_CLAIM_LEASE_MS`, default 3000); answer `{ok:true, granted, pending:true}`. |
