Gets the project up to date for 2026.
- Added deployment-time readiness signaling so CloudFormation waits for the bridge to finish bootstrapping before reporting Create Complete.
- Updated the bridge bootstrap checks to confirm Tor is running, port 8000 is listening, port 8080 is listening, and a hashed fingerprint was generated.
- Added stack outputs for bridge readiness, public IP, instance ID, hashed fingerprint, and a Tor Metrics relay search URL.
- Reworked the verification flow to use CloudFormation outputs and Tor Metrics instead of browser-based SSH access.
- Updated the deployment docs to explain the no-SSH model, Tor Metrics verification, and optional external port checks with nc.
- Switched Tor installation to Tor Project’s apt repository on Ubuntu 24.04 so new bridges track Tor Project’s stable release instead of the Ubuntu archive version.
- Enabled unattended upgrades for both Ubuntu security updates and Tor Project packages for the active Ubuntu codename.
- Added optional bridge customization parameters for BridgeNickname and ContactInfo.
- Modernized the infrastructure defaults with Ubuntu 24.04, t3.micro, encrypted gp3 root storage, IMDSv2, and a tighter subnet layout.
- Removed public SSH ingress from the security group; only the Tor ORPort and obfs4 listener are exposed.
