Move neutral join/leave handlers into GmRelay.Shared so Telegram and Discord share capacity, waitlist, duplicate-click, and schedule-update behavior.
Add Discord component routing for join_session and leave_session buttons with deferred ephemeral replies and serialized schedule message updates.
Bump version to 2.5.0 and update Discord docs.

DiscordPermissionChecker, and DiscordPlatformMessenger.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Add a separate GmRelay.DiscordBot worker using NetCord Gateway with startup token validation, PostgreSQL datasource registration, slash-command setup, component interaction service registration, and lifecycle logging.
Wire the Discord service through Aspire AppHost, Docker Compose, PR checks, deploy image build/push/scan/pull steps, README docs, and synchronized version 2.2.0.
Add TDD coverage for project isolation, token validation, startup wiring, runtime wiring, and version synchronization.
Bump version -> 2.2.0
