feat(digitalocean): Packer nightly snapshot pipeline for fast boot (#2198)
* feat(digitalocean): Packer nightly snapshot pipeline for fast boot

Add pre-built Packer snapshots for DigitalOcean droplets. Instead of
10-20 min cloud-init + agent install on every boot, snapshot-based
droplets boot in ~2-3 min (SSH only, agent pre-installed).

- Packer HCL2 template with parametrized agent/tier builds
- Agent build matrix (packer/agents.json) for all 7 agents
- Tier scripts mirroring cloud-init.ts package tiers
- Nightly GitHub Actions workflow (4 AM UTC, max-parallel: 3)
- Automatic cleanup: keeps only latest snapshot per agent
- CLI: findSpawnSnapshot() looks up pre-built images via DO API
- CLI: waitForSshOnly() skips cloud-init when using snapshots
- CLI: createServer() accepts optional snapshotId, skips user_data
- CLI: main.ts routes to fast path when snapshot detected
- Tests for findSpawnSnapshot() (5 cases, all passing)

* fix(packer): use var-file for install_commands to avoid shell quoting issues

The previous approach passed install_commands as `-var` inline, but
GitHub Actions expands `${{ }}` before shell evaluation — JSON arrays
with `|`, `&&`, and `"` characters break shell quoting.

Fix: generate a `.auto.pkrvars.json` file (auto-loaded by Packer)
using jq with --argjson for safe JSON handling. Also route all
`${{ inputs }}` and `${{ matrix }}` values through env vars to
prevent script injection.
