Electron (tss-party/main.go:717) and Android (tsslib/tsslib.go:477).

Critical fixes to prevent app crashes when screens are kept open for extended periods:
- Add repositoryScope with SupervisorJob for structured concurrency in TssRepository
- Replace detached CoroutineScope(Dispatchers.IO).launch with repositoryScope.launch:
- Session event subscription (line 206)
- Session status polling (line 291)
- Message routing (line 1508)
- Add cleanup() method to properly cancel all jobs and repositoryScope
- Update disconnect() to also cancel sessionStatusPollingJob
- Update MainViewModel.onCleared() to call repository.cleanup()
This ensures all background coroutines are properly cancelled when the ViewModel
is cleared, preventing memory accumulation over time.

Previously, after keygen completed, the Session page would just update the

the "Return Home" button. This could result in a white screen if the button

When a party re-subscribes (e.g., Android reconnects), the old gRPC stream's
defer Unsubscribe() was accidentally removing the NEW subscription from the
subscribers map, causing the party to miss session_started events.
Fix:
- Subscribe() now returns the channel to the caller
- Unsubscribe() now takes the channel and only removes if it matches
- This prevents older streams from removing newer subscriptions

Problem:
- Android initiator/joiner could miss session_started events due to race condition
- Events arriving between joinSession() and _currentSession.value assignment were ignored
- This caused keygen timeout because parties never started the TSS protocol
Solution:
- Add pendingSessionId field set BEFORE joinSession() call
- Modify startSessionEventSubscription() to match events against both activeSession and pendingSessionId
- Clear pendingSessionId on session completion, failure, or cancellation
This ensures session_started events are correctly processed even if they arrive
before _currentSession is fully initialized.

Changed from single 2-second delay to 5 attempts at 500ms intervals.
This provides faster detection while covering a longer window (2.5 seconds total).
The polling loop:
- Checks every 500ms for up to 5 times
- Stops immediately if keygen is already triggered
- Stops if session context changes (user cancelled/navigated away)
This handles the case where the last joiner triggers session_started
but cannot receive the event themselves.

When multiple Android devices join a keygen session nearly simultaneously,
the last joiner may miss the session_started gRPC event because it's sent
before the device has fully set up its event subscription.
This fix adds a 2-second delayed polling check after join to detect if
the session has already started. If the session is in_progress and we
haven't started keygen yet, trigger it via polling instead of relying
solely on the session_started event.

TSS-lib convention: threshold=t means (t+1) signers required.
User expectation: "2-of-3" means 2 signers needed.
Before this fix:
- Keygen used thresholdT directly (e.g., 2)
- TSS-lib interpreted as needing 3 signers (2+1)
- 2-of-3 wallet was actually 3-of-3!
After this fix:
- Both keygen and signing use (thresholdT-1)
- For 2-of-3: tss-lib threshold=1, needs 1+1=2 signers ✓
Files changed:
- tss-party/main.go: keygen and signing both use thresholdT-1
- tss-wasm/main.go: keygen and signing both use thresholdT-1
- pkg/tss/keygen.go: uses config.Threshold-1

but this broke the keygen/sign consistency that TSS-lib requires.
Changes:
- tss-party/main.go: Sign now uses thresholdT (same as keygen)
- pkg/tss/signing.go: Add logging, emphasize threshold must match keygen
- tss-wasm/main.go: Add comment about threshold consistency
NOTE: This fix maintains backward compatibility with existing wallets.
No wallet regeneration is needed.
