fix: job edit schedule format error and refactor services directory

- Fix #25: job update sends schedule as plain string but upstream expects
  { kind, expr, display } object, causing "'str' object has no attribute 'get'"
- Move hermes-cli.ts, hermes.ts, hermes-profile.ts into services/hermes/
  for multi-agent namespacing consistency
- Fix ts-node Set spread compatibility in filesystem.ts
