The extension emits the literal event string "system.heartbeat";
assert the daemon-side serde name serialises to the same value and
round-trips from the exact frame shape the extension sends, so a
future rename cannot silently break keepalive and liveness.

Introduce a `system.heartbeat` protocol event and use it as a
liveness signal on the daemon side.
- Track `last_seen` per connected browser, bumped on every inbound
WS frame (tool response, event, ping/pong, or heartbeat).
- Add a reaper task that drops any browser silent past a 60s window
and purges its sessions, mirroring the WS disconnect cleanup. This
releases half-open connections left behind when the OS resumes from
sleep and kills the service worker without delivering a close frame,
so the daemon no longer pins a phantom "connected" browser and can
idle-exit normally.
- Wire the reaper into both the foreground daemon and the test/embed
entry point, aborting it on shutdown.

Capture user actions in the Agent Window and export a record-only
trace (pages[] + navigate/click/fill/select/press steps with target
descriptors). Adds the record overlay UI aligned with the control
overlay, and wires record start/stop/await through CLI, daemon,
protocol, and extension.
Add `bsk network` as a sibling of the `console` command from #7,
reading the buffered network responses / failures for a tab. Fills the
remaining half of the request in #2 (console landed in #7; network did
not).
Mirrors the console command's conventions exactly:
bsk network --session <id> [--tab-id N] [--since C]
[--limit N] [--max-text-chars N]
The extension enables `Network` on attach (best-effort) and buffers
`responseReceived` / `loadingFailed` events per tab with a monotonic
sequence, correlating them to `requestWillBeSent` for method/URL. Reads
are cursor-paginated (`since` -> `next_since`) and bounded (`limit`,
`max_text_chars`) for agent-context safety, same as console. Entries
carry the real HTTP status code (response) or the CDP failure reason
(failure) — things `performance.getEntriesByType('resource')` can't
give.
Classified read-only (pass-through under the pending-interrupt gate);
defaults to the Agent Window's active tab.
Wires bsk-protocol (Method + params/result/entry structs + schema),
bsk-cli (network subcommand + daemon dispatch allow-list) and the
extension (handler + dispatcher route), with unit / parse / IPC tests
paralleling the console command.
