chore(dev): prepare QuickAdd in T3 worktrees and sandboxes

[chhoumann]

Summary

New QuickAdd worktrees and sandboxes in T3 need dependencies and a built plugin before the first agent turn. Add a repository setup hook so this works from the default branch.

Changes

• Run pnpm install --frozen-lockfile --prefer-offline && pnpm run build when T3 creates a worktree.
• Wait for setup to finish before starting the agent. Setup installs dependencies and generates build files inside the new workspace.

Testing / validation

• pnpm run build-with-lint passed.
• pnpm test passed: 6,864 tests, with 32 skipped.
• Launched a fresh sandbox through T3's native desktop app. Dependencies and main.js existed before the first agent action.
• .agents/run-e2e tests/e2e/cli-list-writes.test.ts passed both tests in isolated Obsidian 1.13.7. The checkout stayed clean.

Checklist

• PR title follows Conventional Commits.
• Related issues: none.
• Release/migration impact: development setup only; no plugin behavior change or data migration.

Note

Add QuickAdd setup script to T3 worktree and sandbox config

Adds a T3 setup script in t3.json that runs a frozen, offline-preferred pnpm install followed by pnpm run build when a worktree is created. The script uses the configure icon and runs synchronously.

Summary by CodeRabbit

• Chores
  • Creating a worktree now automatically installs project dependencies and builds the project. The setup runs synchronously and uses a frozen lockfile with offline installation preference.

Then gathers packages in its math
The lockfile holds each version tight
A build runs next, all neat and right
The rabbit hops away at last}
