Bohan Jiang ae9098637d feat(analytics): suppress PostHog $pageview on desktop tab/workspace switches (#2033)
* feat(analytics): suppress PostHog $pageview on desktop tab/workspace switches

Desktop tab switches were emitting a $pageview every time the user clicked
between already-open tabs (or workspaces), since the tracker fired on any
change to the resolved active path. Real-data audit showed this was the
single largest source of PostHog quota burn — desktop accounted for 51% of
all $pageviews at ~34 pv/user/30d vs web's ~10 — and the re-emitted paths
add no signal because the original navigation already fired.

Detect "tab switch" as `(workspace, tabId)` identity changing while the
surface stays `tab`, and skip the capture in that case while still updating
the ref so the next in-tab navigation compares against the right baseline.
Login transitions, overlay open/close, and intra-tab navigation continue
to fire as before.

* fix(analytics): only suppress $pageview for re-activations of known tabs

Prior commit suppressed every (workspace, tabId) change while the surface
stayed `tab`, which also swallowed the first $pageview for newly opened
tabs (`openInNewTab` / `addTab`) and for cross-workspace `switchWorkspace`
into a not-yet-seen tab.

Track an observed `(workspace, tabId) → path` map seeded from the
persisted tab store on mount. Suppress only when the active key is
already in the map AND its recorded path matches the current path —
i.e. genuine re-activation of an already-known tab. New tabs and
cross-workspace navigation to a fresh tab now correctly emit one
pageview.

Adds a vitest covering the three behaviors GPT-Boy flagged plus the
intra-tab navigation, overlay/login transitions, and persistence-restored
mount paths. Wires the `@/` alias into `vitest.config.ts` so component
tests can resolve renderer-relative imports.

* refactor(analytics): reuse tab-store helpers and inline observed-tabs seed

Replace the two ad-hoc tab selectors with the existing
`useActiveTabIdentity()` + `getActiveTab()` helpers from tab-store, which
already provide the (slug, tabId) primitive pair and the active tab
lookup with the same stability guarantees.

Move the observed-tabs Map seeding from a useEffect into a synchronous
first-render initializer. The seed runs once per mount before any
state-driven effect, so the previous useEffect-then-defensive-fallback
pattern in the second effect was unreachable.
