- dotfiles_manager.sh: add 'deploy-to' command to SCP tracked dotfiles
and scripts directly to servers with no Gitea access
- backs up existing remote files to ~/.dotfiles_backup/remote-<host>-<timestamp>/
before overwriting anything
- flags: --scripts-only, --include-ssh, --no-backup, --dry-run
- ssh/config: reorganize into labeled sections, move work hosts to top,
fix global defaults (proper Host * block, remove deprecated Protocol/KeepAlive),
add inline comments on all port forwards
- README.md: full rewrite with directory layout, profiles, shell layering,
env vars, aliases, bootstrap flow, symlink mechanics, SSH key strategy,
two-machine sync workflow, and deploy-to docs
