Menubar: reduce cache TTL from 300s to 30s, background refresh from
60s to 15s, always fetch fresh data on tab switch instead of serving
stale cache. TUI: default auto-refresh to 30s (--refresh 0 to disable).
Closes#107
Remove the broken "Connect Claude" / "Reconnect Claude" buttons from
the Plan pane -- they opened a terminal session that did nothing useful
for already-logged-in users. Keep only the "Retry" button.
Add an auto-update checker that queries GitHub releases every 2 days in
the background. When a newer menubar build is available, an "Update"
pill appears in the header. Clicking it runs the existing installer
flow (download, replace, relaunch) with no manual steps.
The refresh loop previously skipped `refreshQuietly(.today)` when the
user was already viewing the Today period. That guard meant while the
user was on (today, claude) or any other non-.all provider, the
(today, all) cache went stale. The menubar title and the agent tab
strip both read from that cache, so they displayed stale costs while
the hero section (which reads the currently-viewed payload) showed
the correct fresh value.
Remove the guard so the (today, all) cache refreshes every cycle
regardless of the currently selected period/provider.
Shipped as mac-v0.7.4.
