feat(slack): add private approval previews

[benpankow]

Summary

Adds private delivery for Slack tool approvals. privateToolApprovals can put the preview and controls in an ephemeral thread message or reviewer DM; DM interactions carry the original thread route so they resume the correct parked session. Questions and session-limit prompts keep their existing thread behavior, and missing reviewer identity fails closed without a public fallback.

export default slackChannel({
  privateToolApprovals: {
    delivery: "direct-message", // or "ephemeral"
    when: (request) => request.action.toolName === "review_answer",
    reviewer: (_request, ctx) =>
      String(ctx.session.auth.current?.attributes.reviewerUserId ?? "") || null,
  },
});

Direct messages require the Slack app's im:write scope. This builds on #3055 and #3056; it does not change approval authorization policy.

Validation

Adds tests for ephemeral and DM preview delivery, reviewer targeting, return-route encoding, response decoding, and DM card settlement state.

Package Drill-Down

Package Details

• Package: eve@0.52.0
• Package directory: packages/eve
• Tarball: 8.65 MB (eve-0.52.0.tgz)
• Unpacked payload: 32.59 MB across 3841 published files
• Installed footprint: 77.67 MB across 7739 installed files
• Installed root package: 31.16 MB
• Installed dependencies: 46.51 MB
• Installed package instances: 33
• Distinct installed package names: 32
• Installed dependency edges: 51
• Installed optional peer edges: 7
• Runtime dependencies: 2
• Peer dependencies: 5 (4 optional)

Installed footprint is measured from an isolated temporary npm install of the packed tarball.
Graph metrics read only package.json files in package directories directly beneath a node_modules boundary, including nested boundaries. Each directory is one package instance; distinct names come from those manifests. Dependency edges count each unique name in dependencies or optionalDependencies per instance; optional peer edges count peerDependencies marked optional.

Build Timing: e2e/fixtures/agent-tools-sandbox

This is an informational timing measurement inside eve build, from preflight through publication. Output-size measurement and profile writing are excluded.

Build mode: deployable Vercel build with sandbox template prewarm included.

• Build pipeline: 2.43 s -> 2.34 s (-93.3 ms) vs benpankow/turn-rollback-tasks (be6194b).
• Timing is informational: shared GitHub runners are too variable for a hard timing budget.

Additional Suggestion:

In task-mode turns, the TurnCommitEventGate withholds the terminal message.completed event but nothing ever releases it (and a turn-commit checkpoint is created but never resolved) whenever the bundle registers any beforeTurnCommit hook.
