johba 9050413994 refactor: split supervisor into infra + per-project, make poll scripts config-driven
Supervisor split (#26):
- Layer 1 (infra): P0 memory, P1 disk, P4 housekeeping — runs once, project-agnostic
- Layer 2 (per-project): P2 CI/dev-agent, P3 PRs/deps — iterates projects/*.toml
- Adding a new project requires only a new TOML file, no code changes

Poll scripts accept project TOML arg (#27):
- dev-poll.sh, review-poll.sh, gardener-poll.sh accept optional project TOML as $1
- env.sh loads PROJECT_TOML if set, overriding .env defaults
- Cron: `dev-poll.sh projects/versi.toml` targets that project

New files:
- lib/load-project.sh: TOML to env var loader (Python tomllib)
- projects/versi.toml: current project config extracted from .env

Backwards compatible: scripts without a TOML arg fall back to .env config.

Closes #26, Closes #27
