* feat(docker): replace Packer snapshots with Docker-based agent delivery
Docker images on GHCR are public and cross-account, unlike DO snapshots
which are private/account-scoped. Cloud-init installs Docker + pulls the
agent image during boot. The install step extracts pre-built binaries via
`docker cp` and falls back to normal install if unavailable.
- Add Dockerfiles for all 7 agents (claude, codex, openclaw, opencode,
kilocode, zeroclaw, hermes)
- Convert docker.yml to matrix build for all agents
- Add tryInstallFromDocker() shared helper with Docker-first install
- Add Docker pull to DigitalOcean cloud-init userdata
- Remove Packer snapshot pipeline, lookup, and SSH-only wait
- Remove packer/ directory (HCL templates, tier scripts, agents.json)

* security: address review findings in docker agent delivery
- Add agentName validation regex (/^[a-z0-9-]+$/) in digitalocean.ts
before interpolation into cloud-init script
- Quote dockerImage variable in all docker command strings in
agent-setup.ts to prevent command injection
- Restrict docker cp to specific known directories (.claude, .bun,
.local, .npm, .cargo, .opencode) instead of blanket /root/.
