* fix(web,build): search palette hang on numeric query + graceful SSE shutdown (BUG-1531)
CommandPalette's reactive `$effect` subscribed to every workspace's
`localSearch.epoch` + `localIndex.bootstrapStateFor`. Bare-digit queries
short-circuit to `exactItemNumberLookup` (synchronous, very fast) and
stacked re-fires of the effect inside one microtask tick whenever an SSE
delta arrived — Svelte tripped `effect_update_depth_exceeded` and the
palette froze. Treat bare-digit queries the same as `body:` queries
(skip the subscription reads) and wrap `doSearch()` in `untrack()` so
its internal reactive reads can't smuggle hidden dependencies into the
effect.
The SSE churn that fanned the loop was rooted in `make install` using
`killall -9` — SIGKILL drops every open SSE stream mid-chunk so every
browser tab logs `ERR_INCOMPLETE_CHUNKED_ENCODING` and reconnects.
Switch to SIGTERM + 5s wait + SIGKILL fallback so the server's existing
graceful-shutdown path (cmd/pad/main.go:811-857) actually runs and the
http.Server writes a final 0-chunk on each open stream.
Follow-up tidy-ups (unchecked write errors in writeSSEEvent, link the
30s keepalive to the 120s IdleTimeout in code) tracked in BUG-1532.
* fix(web): track workspace slug in palette $effect per Codex review (round 1)
After wrapping doSearch() in untrack(), the workspaceStore.current?.slug
read that doSearch performs at line 209 no longer registered as a
tracked dep of the search effect. The non-body / non-bare-digit branch
still reads the slug via localIndex.bootstrapStateFor(...), so workspace
switches re-fire the effect for that branch — but body: and bare-digit
queries skip that block entirely. Without an explicit slug subscription
they wouldn't re-dispatch on workspace switch; an in-flight server
response would land stale, get discarded by isSameDispatch(), and
loading could stick true.
Hoist `void workspaceStore.current?.slug` into the unconditional void
block so all four query shapes re-fire on workspace switch.
Refs BUG-1531.
* chore: gofmt handlers_claim_code_test.go
Drive-by formatting fix to unblock CI on this PR. The file landed
slightly unaligned in #586 (TASK-1525) — gofmt straightens the struct
tag column on claimCodeResponse.
