added PyInstaller builds, AGPLv3, transport config

- Add pyinstaller.spec and GitHub/Forgejo CI workflows for cross-platform builds
- Add AGPLv3 license
- Move data storage to ~/.tinyweb/
- Add --version and --port CLI flags
- Add transport node selection in /style (smart regeneration preserves Reticulum config)
- Add discover more nodes link to rmap.world
