[ECC 2.0] Module 1: Automatic worktree creation per session

[affaan-m]

Automatic worktree creation per session

Each agent session automatically gets its own git worktree, enabling parallel development without branch conflicts. On session create, a new worktree is provisioned at a configured path; on session destroy, the worktree is cleaned up. Integrates with the session lifecycle from issue #1.

Already shipped in ECC2.

Implemented surface:

• config-backed default auto_create_worktrees = true in ecc2/src/config/mod.rs
• session start/spawn paths honor the policy and create dedicated git worktrees in ecc2/src/session/manager.rs via ecc2/src/worktree/mod.rs
• CLI override flags exist in ecc2/src/main.rs (--worktree / --no-worktree)
• TUI spawn/assign flows use the same policy in ecc2/src/tui/dashboard.rs
• cleanup paths already remove or prune worktrees on merge, delete, cleanup, and inactive-session prune flows across manager.rs, dashboard.rs, and daemon.rs

This issue is stale relative to the shipped ECC 2.0 worktree lifecycle, so I’m closing it.

Closing as already shipped in ECC2 automatic worktree lifecycle work.
