- Add setup/cross_host_ssh.sh to establish ed25519 SSH trust between
Unraid and Fedora (required by backup/restore scripts for direct SCP)
- Add ssh_key and authorized_key cleanup handlers to setup/cleanup.sh
- Rewrite phase8 cutover to mark GitHub repos as mirrors instead of
archiving them (archived repos reject push mirror writes), with a
JSON state snapshot of pre-cutover settings (description, homepage,
wiki, projects, Pages) for exact restoration on teardown
- Rewrite phase8 teardown to restore from state snapshot with fallback
to legacy "— was:" description parsing
- Make migration polling configurable via MIGRATION_POLL_INTERVAL_SEC
and MIGRATION_POLL_TIMEOUT_SEC in .env (was hardcoded 120s/3s)
- Fix preflight SSL validation: check SSL_MODE instead of always
requiring SSL_EMAIL, add conditional checks per SSL_MODE
- Add preflight checks 23-24: cross-host SSH connectivity
- Add --start-from range validation and cross_host_ssh.sh to run_all.sh
