fix: unblock the server event loop (0.0.40) (#61)

* fix: unblock server event loop subprocesses

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

* test: let native-world wait for the SQLite writer instead of failing

The suite intermittently died with "database is locked" - four times today,
including once on CI for an unrelated PR, and repeatedly while verifying the
event-loop fix. It opens 38 of its own DatabaseSync connections to
ctrl-pane.db while the server process holds the same file, and with no busy
timeout SQLite returns SQLITE_BUSY immediately rather than waiting for the
writer to finish.

Every test-side connection now waits up to 15s for a lock, which is what a
real client does. Five consecutive native-world runs pass where the same
build previously failed roughly one run in three.

This is a harness race, not a product defect, and no assertion changed.

* release: 0.0.40

Version, changelog and the local/1helm-channel-machine:0.0.40 pins, plus the
offline release fallback pointed at 0.0.40 with fail-closed placeholder
digests until this commit's artifacts exist.

+### Fixed
+
+- Clicking a channel or a thread no longer takes seconds. The server made
+  subprocess calls synchronously on the only thread that serves HTTP, so every
+  request queued behind them. Sampling a trivial endpoint that normally answers
+  in 1 ms recorded stalls of 2.9 s, 3.2 s and 21.2 s while the interface was in
+  use — the click was never slow, it was waiting in line.
+  - Durable memory shelled out to its Python bridge with `execFileSync`,
+    blocking the event loop for the whole call: a 20-second timeout for most
+    operations, 120 seconds for transcript sync, and a 771 ms floor just to
+    import the embedding libraries. The 21.2 s stall was that timeout. It is now
+    asynchronous, along with the runtime probes it depends on, which turned out
+    to be reachable from the first memory operation on a request path rather
+    than only at setup.
+  - Runtime readiness ran a synchronous container-image check on request
+    handlers including `/api/computers`, costing 53–73 ms of blocked event loop
+    every time. Readiness is now cached with a short time-to-live and refreshed
+    out of band, with one shared refresh so concurrent requests cannot cause a
+    subprocess storm. Endpoints that act on readiness — setup completion and
+    runtime start or prepare — await a fresh check rather than trusting the
+    cache, and image preparation updates it directly so a stale result cannot
+    persist.
+  - A channel interaction inspected the same container twice in a row; the
+    redundant call is gone.
+
+  This was the same defect that froze the Windows interface before 0.0.39. That
+  release removed the boundary those calls crossed without removing the
+  blocking, so Linux and macOS kept paying it.
+
+
