chore(pi): organize mode implementations

[BillLeoutsakosvl346]

Summary

• move PI implementations and colocated tests into explicit core, cloud, and local folders
• update direct imports and test mocks for the relocated files
• keep the existing PI handler, mode logic, execution behavior, and public interfaces unchanged

Type of Change

• Refactor

Testing

• PI executor and block suites (22 files, 360 tests)
• full workspace type-check
• lint, block registry, import specifiers, monorepo boundaries, and the complete pre-ship audit suite

Checklist

• Code follows project style guidelines
• Self-reviewed my changes
• Existing tests pass after relocation
• No new warnings introduced
• I confirm that I have read and agree to the terms outlined in the Contributor License Agreement (CLA)

PR Summary

Low Risk
Mechanical path refactor with no described logic changes; risk is limited to missed import or mock path updates rather than runtime behavior changes.

Overview
Reorganizes the Pi executor handler tree so shared types and utilities live under core/, E2B/GitHub flows under cloud/ (authoring, babysit, review, shared helpers), and local execution under local/, with search/ unchanged at the top level.

What moves: flat files such as backend, keys, context, events, redaction, and pi-sdk → core/; cloud-backend, cloud-shared, github-pr, babysit modules, and review tools → nested cloud/ paths; local-backend, sim-tools, and ssh-tools → local/.

What stays the same: pi-handler remains the entry point; mode routing, sandbox/git security behavior, and public type surfaces are not intentionally changed—only import paths and Vitest mock targets are updated (including the Pi block test that imports PI_SEARCH_PROVIDERS from core/keys).

Greptile Summary

The PR reorganizes the PI executor implementation into explicit core, cloud, and local areas without changing its public handler interface.

• Moves shared contracts, event handling, key resolution, SDK integration, and redaction into core/.
• Groups cloud authoring, review, babysit, GitHub, and shared sandbox code under cloud/.
• Groups local execution and tool implementations under local/.
• Updates runtime imports, test imports, and mocks to use the relocated modules.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
