Move reasoning.ts and waiting-for-approval.ts to runtime folder

[Copilot]

This PR reorganizes the codebase by moving two files to the runtime folder as requested in issue #XX:

Changes

• Moved context/reasoning.ts → runtime/reasoning.ts
• Moved checks/waiting-for-approval.ts → runtime/waiting-for-approval.ts

Rationale

These files are being relocated to the runtime folder to better align with the architectural organization of the syner OS. The runtime folder is intended to contain core runtime functionality including cancellation, retries, timeouts, and now reasoning and approval workflows.

This consolidates runtime-related features into a single location, making the codebase more maintainable and the folder structure more intuitive.

Impact

• No functional changes - both files are currently empty placeholders
• No imports or references to update - verified via codebase search
• File history preserved using git mv

The runtime folder now contains all core runtime features:

• cancel.ts
• index.ts
• reasoning.ts ✨ (newly added)
• retries.ts
• timeout.ts
• waiting-for-approval.ts ✨ (newly added)
