feat: inject workspace config into daemon sessions

[arek-e]

Summary

When a daemon is linked to a workspace, session env vars are now injected:

PAWS_WORKSPACE_NAME=paws
PAWS_WORKSPACE_TYPE=monorepo
PAWS_WORKSPACE_REPO=arek-e/paws
PAWS_WORKSPACE_ROOT_DIR=/
PAWS_WORKSPACE_BRANCH=main
PAWS_CLONE_URL=https://github.com/arek-e/paws.git
PAWS_WORKSPACE_LANGUAGE=typescript
PAWS_WORKSPACE_PACKAGE_MANAGER=bun

For multi-repo workspaces, also injects PAWS_WORKSPACE_REPOS (comma-separated).

Works at both dispatch sites: webhook/schedule triggers and GitHub PR triggers.

Test plan

• 0 lint errors, 42/42 typecheck, 31/31 tests

Summary by CodeRabbit

• New Features
  • Sessions now automatically inject workspace-specific environment variables, including repository details, clone URLs, and settings-derived configuration (language, package manager, test/build commands).
  • GitHub app webhook-triggered sessions now include enriched workspace context for improved session initialization.
  • Multi-repository workspace support with aggregated repository information injected into session environments.

📝 Walkthrough

Walkthrough

This pull request adds workspace-aware environment injection into session and workload dispatch. A new helper function computes workspace-derived environment variables (including repository details and build/test commands) and injects them into workload environments during session creation for both daemon-triggered and GitHub webhook-triggered sessions. Type definitions are updated to include an optional workspace field on daemon interfaces.

Changes

Cohort / File(s)	Summary
Workspace Environment Injection apps/control-plane/src/app.ts	Added injectWorkspaceEnv() helper to compute and merge PAWS_WORKSPACE_* environment variables from workspace store. Updated daemon-triggered and GitHub webhook session creation to inject workspace env into workload.env; gracefully falls back to original env if workspace is missing or lookup fails.
Type Definitions apps/control-plane/src/store/daemons.ts, packages/integrations/src/types.ts	Added optional workspace?: string field to StoredDaemon and GitHubDaemon interfaces. No changes to persistence or mapping logic.

Poem

🐰 A workspace bloom unfolds today,
Where env vars dance and play,
From daemon's nest to session's keep,
Workspace secrets flow so deep! ✨
