feat(delegation): persist thread watches across Host Runtime restarts - #726
Add four OpenSpec changes:
- persist-thread-watches: watches survive a Host Runtime restart
- add-external-client-access: named clients, local listener, refs,
event log with SSE and long-poll, MCP tools
- add-remote-client-access: scopes, tailnet and Funnel access, OAuth
pairing, webhook adapters (Grok Bot first)
- add-local-design-preview: open local HTML in the built-in browser
with live reload

Cap the post-restart grace at 5 minutes, hold restored notifications
until the notified Thread is reachable, and state that several Runtimes
sharing a data directory each own their watches and adopt only those
left by exited processes.

Watches were held only in Host Runtime memory, so a restart during a
long delegated stage silently dropped the notification that should wake
the parent Thread.
- Store each watch as a private per-watch record owned by the Runtime
process; a starting Runtime adopts records of exited processes,
claiming each with an atomic rename so only one Runtime takes it.
- Deadlines are absolute; restored watches wait up to 5 minutes for
their sessions before read failures count, and restored notifications
wait until the notified Thread is readable.
- A send is recorded as in progress before it starts, so a restart
during the send delivers again (at least once across restarts). An
unknown outcome while the Runtime runs is still not retried.

Acceptance on macOS showed that restarting the Host Runtime ends the
Harness processes it owns, and the Turn that was running then reads as
completed, so a restored watch told the parent the work was done.
The watch now records the Turn it last saw running (persisted when it
changes). After a restart, if the first read shows that same Turn as
terminal, the notification reports interrupted and says the restart
ended it. A later Turn, or the same Turn still running, is reported as
before. A Turn held by a long-running remote listener that genuinely
finished during the downtime is also reported as interrupted; the
notified side reads the Thread before acting either way.
Also log how many watches a Runtime restored.

Watch persistence and restart recovery mostly work, but a failed first save can leave an orphan record that later sends a notification, and a clock jump can cause two Runtimes to take over the same watch. Restart explanations are also lost after a second restart. Several spec and design inconsistencies in the added proposals are still open. Resolve or explicitly accept these before merging.

The macOS re-test showed the previous check was not enough: claude-code
restored the cut-off Turn under a new Turn id, so it was still reported
completed, and cursor-cli could not reopen the session at all, so the
watch reported notFound after the grace period.
A watch that was observing a running Thread before a restart now
reports interrupted when the first successful read after the restart is
already terminal, whatever the Turn id, and also when the Thread still
cannot be opened once the restore grace ends. The notification says
what happened and what it read as, and the explanation is stored with
the watch so a further restart keeps it. A Thread still running on the
first read is reported normally when it stops. Tracking the running
Turn id is no longer needed and is removed.

Windows CI failed "lets only one of two concurrent adopters take a
record": both adopters returned the watch. An adopter read the exited
owner's record, another adopter claimed and re-saved it under its own
owner, and the first adopter's claim rename then took that live record
and adopted it again.
After the claim rename, compare the claimed file with what was read. If
it changed, hand it back with link (which never replaces a newer record)
and skip it. Claim names also get a random suffix so two stores in one
process never share a claim. A new test pauses the claim rename to
reproduce the interleaving deterministically.
