Alex P b0494e8eef security: prevent video access for pending/denied sessions
CRITICAL SECURITY FIX: Pending sessions (awaiting approval) were granted
video.view permission, allowing denied sessions to see video when they
reconnected.

**Vulnerability:**
1. Session requests access and enters pending mode
2. Primary session denies the request
3. Denied session clicks "Try Again" and reconnects
4. New session enters pending mode but has video.view permission
5. User can see video stream despite being denied

**Fix:**
Remove PermissionVideoView from SessionModePending. Pending sessions now
have NO permissions until explicitly approved by the primary session.

This ensures:
- Denied sessions cannot access video on reconnection
- Only approved sessions (observer/queued/primary) can view video
- CanReceiveVideo() properly blocks video frames for pending sessions

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)
