[feat]: init commands

[aqeelat]

Feature Summary

The ability to run commands when a task is created, before the agent is run.

Problem or Use Case

When creating a new worktree, I always need to run pnpm i.

Proposed Solution

Allowing per-project config that allows users to set a command to be sent to the terminal whenever a new worktree is created.

Alternatives Considered

I currently have it as part of my agents.md, but I would love it if it can be run independent of the agent.

Additional Context

I'm working on the implementation and I would like to open a pr soon.

Definitely needed! A few thoughts:

Existing scaffolding: There’s a ProjectRunConfigService.ts and DB migration (0003_add_run_config_status_to_projects.sql) from PR #497 / @Musti7even that were never wired up. The service was intended for autogenerated configs, not user-defined commands, so it’s probably not directly reusable - but the .emdash/config.json location it targets could be a good home for this.

Design questions:

1. Should commands run in the visible terminal (so you can see pnpm i output) or silently in the background? -> I am thinking visible
2. Any interest in supporting both project-level and global defaults (e.g., always run nvm use for all projects)?
3. Should there be a way to skip init commands for a specific task? (e.g., --no-init equivalent)

Happy to help clean up the dead code or review the PR when you have it ready.
