Extract current round number from tss-lib message type string using
regex pattern `Round(\d+)`. This enables real-time progress updates
(1/4, 2/4... for keygen, 1/9, 2/9... for signing) instead of only
showing completion status.
Changes across all three platforms:
- tss-wasm/main.go: Add extractRoundFromMessageType() and call
OnProgress with parsed round on each outgoing message
- service-party-android/tsslib/tsslib.go: Same implementation for
Android gomobile binding
- service-party-app/tss-party/main.go: Same implementation for
Electron subprocess, with isKeygen parameter to distinguish
keygen (4 rounds) vs signing (9 rounds)
Safe fallback: Returns 0 if parsing fails, which doesn't affect
protocol execution - only UI display.

Previously, after keygen completed, the Session page would just update the
status to 'completed' but not navigate away. Users had to manually click
the "Return Home" button. This could result in a white screen if the button
wasn't visible or clickable.
Now the page auto-navigates to home after 2 seconds, giving users time to
see the completion status and public key before redirecting.

Previously, the network badge (testnet/mainnet) in Layout sidebar only
loaded once on mount and didn't update when user changed network in
Settings page.
Changes:
- Layout.tsx: Read network from localStorage first (consistent with
transaction.ts), then fallback to Electron API
- Layout.tsx: Listen for 'storage' event (cross-tab) and custom
'kava-network-change' event (same-tab) to update display
- Settings.tsx: Dispatch custom event when switching networks so
Layout can update immediately
Android app doesn't have this issue - it uses StateFlow which
automatically triggers re-renders when settings change.

Additional safeguards to prevent "CANCELLED: Cancelled on client" error:
1. Add `this.connected` check at the start of subscribeMessages()
2. Set messageStream to null after canceling old stream
3. Wrap new stream creation in try-catch to handle creation errors
4. Add logging for ignored cancel errors
These changes ensure that:
- subscribeMessages won't proceed if connection is lost
- Old stream is fully cleaned up before creating new one
- Errors during stream creation are properly caught and logged

Root cause: After keygen/sign completion, the gRPC message stream was not
unsubscribed. On the second operation, prepareForSign/prepareForKeygen
would try to cancel the stale stream, causing "CANCELLED: Cancelled on client".

- Add grpcClient.unsubscribeMessages() in all cleanup paths:
- participateKeygen close handler
- participateKeygen error handler

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
- pkg/tss/signing.go: uses config.Threshold-1
BREAKING CHANGE: Existing wallets created before this fix used wrong
threshold and need to be regenerated. New wallets will work correctly.

The signing code was using thresholdT-1 while keygen was using thresholdT,
causing Lagrange coefficient mismatch and "U doesn't equal T" error in round 9.
Root cause: commit d0c504dc added -1 to signing threshold to "match user expectation",
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.
ROLLBACK: If this causes issues, revert to commit before this one.
Previous signing threshold was thresholdT-1 (commit d0c504dc).

When signing with fewer parties than keygen (e.g., 2-of-3 signing with only 2 parties),
the TSS-lib requires filtered save data containing only the participating parties.
Without this fix, signing fails with "U doesn't equal T" error because:
- Keygen creates save data for all N parties (e.g., 3 parties with indices 0, 1, 2)
- Sign uses only T parties (e.g., 2 parties with indices 1, 2)
- TSS-lib internal index validation fails due to mismatch
Changes:
- pkg/tss/signing.go: Use len(sortedPartyIDs) for partyCount and call BuildLocalSaveDataSubset
- tss-party/main.go: Add BuildLocalSaveDataSubset call for Electron app
- tss-wasm/main.go: Add BuildLocalSaveDataSubset call for WASM builds
This fix is backward compatible - when all parties participate, the subset equals the original data.

The tss.NewParameters() expects the party count to match the number of
parties in peerCtx. For signing, this should be len(sortedPartyIDs)
(actual signing participants), not thresholdN (original keygen parties).

co-managed signing with parties at indices 2,3,4.

When switching message/event streams, the old stream's 'end' or 'error'
events could fire after the new stream was created. Since activeMessageSubscription
was already updated to the new session, the old stream's events would
incorrectly trigger reconnection, causing TSS message routing to fail.
Fix:
- Remove event listeners from old stream before canceling
- Use closure to capture current stream reference
- Check if event is from current active stream before triggering reconnect
This fixes the "Not connected" error during co-sign TSS message routing.

The TSS signing was failing with "U doesn't equal T" error because
tss-party was passing incorrect parameters to tss.NewParameters():
- Was: len(sortedPartyIDs)=3 (signing participants), thresholdT-1=2
- Now: thresholdN=5 (keygen N), thresholdT=3 (keygen T)
This matches how pkg/tss/signing.go creates parameters in server-party,
