Bundle top-level code runs during `workflow add` (descriptor extraction),
but agent config env vars (e.g. WORKFLOW_HERMES_COMMAND) are only available
at `workflow run` time. Deferring validation prevents premature throws.
BREAKING: HermesAgentConfig.command and CursorAgentConfig.command are now
required string fields (absolute path to CLI binary). Validation rejects
non-absolute paths at construction time.
- Eliminates PATH resolution ambiguity in spawned worker processes
- spawnCli: explicit env: process.env for clarity
- bundle-entry: WORKFLOW_CURSOR_COMMAND is now required
- Updated tests for both agents
