"""Wire the task manager into the project it sits in.

    python3 .task-manager/install.py --dry-run   # report only, change nothing

Vendor-specific wiring belongs to the configured agent adapter: this script
resolves the adapter (BOARD_AGENT_ADAPTER in manager/local/.env, default
"claude"; local/adapters/ overrides core/adapters/) and runs its `wire`
executable against the project root. Safe to run any time — after dropping
.task-manager/ into a new repo, and after every update.sh.
