Alex P 825299257d fix: correct grace period protection during primary reconnection
The session manager had backwards logic that prevented sessions from
restoring their primary status when reconnecting within the grace period.
This caused browser refreshes to demote primary sessions to observers.

Changes:
- Fix conditional in AddSession to allow primary restoration within grace
- Remove excessive debug logging throughout session manager
- Clean up unused decrActiveSessions function
- Remove unnecessary leading newline in NewSessionManager
- Update lastPrimaryID handling to support WebRTC reconnections
- Preserve grace periods during transfers to allow browser refreshes

The fix ensures that when a primary session refreshes their browser:
1. RemoveSession adds a grace period entry
2. New connection checks wasWithinGracePeriod and wasPreviouslyPrimary
3. Session correctly reclaims primary status

Blacklist system prevents demoted sessions from immediate re-promotion
while grace periods allow legitimate reconnections.

Alex P 57f4be2846 fix: clear transfer blacklist on primary disconnect to enable grace period promotion
When a primary session disconnects accidentally (not intentional logout), the
60-second transfer blacklist from previous role transfers was blocking observer
sessions from being promoted after the grace period expires (~10s).

The blacklist is intended to prevent immediate re-promotion during manual
transfers (user-initiated), but should not interfere with emergency promotion
after accidental disconnects (system-initiated).

Changes:
- Clear all transfer blacklist entries when primary enters grace period
- Add logging to track blacklist clearing for debugging
- Preserve blacklist during intentional logout to maintain manual transfer protection

This ensures observers are promoted after grace period (~10s) instead of
waiting for blacklist expiration (~40-60s).

Alex P b388bc3c62 fix: reduce observer promotion delay from ~40s to ~11s
1. Terminal access permission check:
   - Add Permission.TERMINAL_ACCESS check to Web Terminal button
   - Prevents observer sessions from accessing terminal

2. Immediate websocket cleanup:
   - Close peer connection immediately when websocket errors
   - Previously waited 24+ seconds for ICE to transition from disconnected to failed
   - Now triggers session cleanup immediately on tab close

3. Immediate grace period validation:
   - Trigger validateSinglePrimary() immediately when grace period expires
   - Previously waited up to 10 seconds for next periodic validation
   - Eliminates unnecessary delay in observer promotion

Timeline improvement:
Before: Tab close → 6s (ICE disconnect) → 24s (ICE fail) → RemoveSession → 10s grace → up to 10s validation = ~50s total
After: Tab close → immediate peerConnection.Close() → immediate RemoveSession → 10s grace → immediate validation = ~11s total

Alex P ba8caf3448 debug: add detailed logging to trace session addition flow
Add comprehensive logging to identify why sessions fail to be added to
the session manager:
- Log entry/exit points in AddSession
- Track reconnection path execution
- Log max sessions limit checks
- Trace AddSession call and return in handleSessionRequest

This will help diagnose why sessions get stuck at ICE checking state
without being properly registered in the session manager.

Alex P 541d2bd77d fix: correct grace period protection during primary reconnection
- Remove broken bypass logic that caused immediate observer promotion on refresh
- Add session map debugging logs to validateSinglePrimary
- Ensure grace period properly blocks auto-promotion until expiration

Alex P f9ebd6ac2f feat: add strict observer-to-primary promotion controls and immediate logout promotion
Observer-to-primary promotion protections:
- Block auto-promotion during active primary grace periods
- Prevent creating multiple primary sessions simultaneously
- Validate transfer source is actual current primary
- Check for duplicate primaries before promotion

Immediate promotion on logout:
- Trigger validateSinglePrimary() immediately when primary disconnects
- Smart grace period bypass: allow promotion within 2 seconds of disconnect
- Provides instant promotion on logout while protecting against network blips

Enhanced validation and logging:
- Log session additions/removals with counts
- Display session IDs in validation logs for debugging
- Track grace period timing for smart bypass decisions

Alex P a1548fe5b1 feat: improve session approval workflow with re-request and rejection limits
Backend improvements:
- Keep denied sessions alive in pending mode instead of removing them
- Add requestSessionApproval RPC method for re-requesting access
- Fix security issue: preserve pending mode on reconnection for denied sessions
- Add MaxRejectionAttempts field to SessionSettings (default: 3, configurable 1-10)

Frontend improvements:
- Change "Try Again" button to "Request Access Again" that re-requests approval
- Add rejection counter with configurable maximum attempts
- Hide modal after max rejections; session stays pending in SessionPopover
- Add "Dismiss" button for primary to hide approval requests without deciding
- Add MaxRejectionAttempts control in multi-session settings page
- Reset rejection count when session is approved

This improves the user experience by allowing denied users to retry without
page reloads, while preventing spam with configurable rejection limits.

Alex P b322255684 fix: resolve all Go and TypeScript linting issues
Address all linting warnings and errors in both backend and frontend code:

**Go (golangci-lint):**
- Add error checking for ignored return values (errcheck)
- Remove unused RPC functions (unused)
- Fix import formatting (goimports)

**TypeScript/React (eslint):**
- Replace all 'any' and 'Function' types with proper type definitions
- Add RpcSendFunction type for consistent JSON-RPC callback signatures
- Fix React Hook exhaustive-deps warnings by adding missing dependencies
- Wrap functions in useCallback where needed to stabilize dependencies
- Remove unused variables and imports
- Remove empty code blocks
- Suppress exhaustive-deps warnings where intentional (with comments)

All linting now passes with 0 errors and 0 warnings.

Alex P cd70efb83f feat: multi-session support with role-based permissions
Implements concurrent WebRTC session management with granular permission control, enabling multiple users to connect simultaneously with different access levels.

Features:
- Session modes: Primary (full control), Observer (view-only), Queued, Pending
- Role-based permissions (31 permissions across video, input, settings, system)
- Session approval workflow with configurable access control
- Primary control transfer, request, and approval mechanisms
- Grace period reconnection (prevents interruption on network issues)
- Automatic session timeout and cleanup
- Nickname system with browser-based auto-generation
- Trust-based emergency promotion (deadlock prevention)
- Session blacklisting (prevents transfer abuse)

Technical Implementation:
- Centralized permission system (internal/session package)
- Broadcast throttling (100ms global, 50ms per-session) for DoS protection
- Defense-in-depth permission validation
- Pre-allocated event maps for hot-path performance
- Lock-free session iteration with snapshot pattern
- Comprehensive session management UI with real-time updates

New Files:
- session_manager.go (1628 lines) - Core session lifecycle
- internal/session/permissions.go (306 lines) - Permission rules
- session_permissions.go (77 lines) - Package integration
- datachannel_helpers.go (11 lines) - Permission denied handler
- errors.go (10 lines) - Error definitions
- 14 new UI components (session management, approval dialogs, overlays)
