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
Pure refactor with import path updates only; Pi handler routing and sandbox logic are unchanged, so risk is limited to missed import rewrites rather than functional regressions.

Overview
Reorganizes the Pi executor handler tree so shared code lives under core/, sandbox/GitHub modes under cloud/ (authoring, babysit, review, shared helpers), and local dev under local/, with tests moved alongside each module.

Import paths are updated everywhere that referenced the old flat filenames (e.g. keys → core/keys, cloud-backend → cloud/authoring/backend, babysit-github → cloud/babysit/github, sim-tools → local/sim-tools). The Pi block test now imports PI_SEARCH_PROVIDERS from core/keys to keep block and executor registries aligned.

pi-handler and all affected Vitest mocks point at the new locations; runtime behavior, mode routing, and public types are unchanged—this is structure and references only.

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.
