- Transition `of_config_versions` primary key from `id` to `version` string.
- Add database migration files for PostgreSQL and SQLite.
- Introduce GORM hooks to preserve JSON backward compatibility.
- Remove all localized private structures (`configVersionRecord`, `configVersionRow`) across `agent` and `flared` modules.
- Remove local database Row structures (`tlsCertificateRow`, `tunnelNodeRow`, `pagesProjectRow`) in `proxy_route` module.
- Reuse `model` query methods directly to fetch active config, tunnel nodes, and pages projects.
- Cache IP detection results in memory with a 10-minute TTL to prevent frequent HTTP egress queries to realip.cc.
- Integrate multiple fallback IP lookup providers (ifconfig.me, ip.sb, icanhazip.com) to guarantee IP detection reliability.
- Align agent, relay, and flared to dynamically resolve IP during heartbeat using the nodeip package (when not manually configured).
- Update GeoIP outbound IP strategy to prefer IPv4 HTTP client lookup using tcp4 dialer and fall back to dual-stack tcp.
- Optimize agent profile fingerprinting to exclude dynamic UptimeSeconds and ReportedAtUnix fields, preventing redundant updates.
- Refactor unit tests to prevent outbound network queries during tests.
- Merge all files inside openflare-server to the repository root directory.
- Relocate agent, relay, and flared subprojects from internal/ to internal/apps/.
- Combine docker-compose files and update build context paths to root.
- Update GitHub workflows and Dockerfiles to refer to new directories and package names.
- Rewrite Go package imports across all files.
- Resolve database renew test race condition and clean up docs.
