fix(app): reconnect quickly after phone sleep

[frahlg]

What

• replace a stale foreground WebSocket when no fresh box frame arrives within 2.5 seconds
• give the first Noise handshake after a wake a 3-second deadline instead of inheriting the 12-second background wait
• react to visibility, page restore and network-online events without redialling a healthy stream
• add local performance marks for app open, key readiness, reconnect and first live frame
• include the safe automatic service-worker handover and visible build identity from the prior verified commit

Why

A real app wake took 20–40 seconds before fresh data appeared. The source path could wait for a 12-second Noise deadline and then 3/6/12-second retry windows while a browser still reported a dead socket as open.

The new foreground path gives a healthy stream one normal telemetry beat to answer. If it stays quiet, the app replaces the carrier instead of waiting for those stale timers.

Evidence

Before: the old retry chain allowed waits in the reported 20–40 second range.

After, deterministic tests assert:

• a healthy resumed stream keeps its socket
• a silent open stream redials at exactly 2.5 seconds
• a network change redials at once
• a foreground Noise handshake times out at 3 seconds
• duplicate lifecycle wake events create only one new relay dial

No phone trace is claimed here because Chrome DevTools remote tracing was unavailable in this environment.

Verification

• npm run verify
• Svelte check: 0 errors, 0 warnings
• Vitest: 88 files passed, 1 skipped; 860 tests passed, 1 skipped
• production Vite build passed
• relay integration test passed with its local loopback port
• git diff --check

Refresh visibility before handling pageshow

When a page was previously hidden and is restored without a visibilitychange event—the exact fallback this method is intended to provide—documentVisible remains false, so this guard discards pageshow and never starts the reconnect watchdog. Read the current document.visibilityState here, or have the pageshow handler synchronize visibility before calling this method, so a restored stale socket is actually replaced.
