[Critical] Split oversized loop.ts (615 lines exceeds 500 limit)

[randomm]

Problem

packages/opencode/src/core/loop.ts is 615 lines, exceeding the 500-line hard limit per AGENTS.md.

Multiple responsibilities:

• Loop state management
• Message loading
• Tool resolution (~90 lines)
• Memory retrieval (~40 lines)

Solution

Extract into separate modules:

1. packages/opencode/src/core/tools.ts (~90 lines) - Tool resolution logic
2. packages/opencode/src/core/memory-retrieval.ts (~40 lines) - Memory retrieval logic

Files

• packages/opencode/src/core/loop.ts (split into 3 files)

OBSOLETE: loop.ts no longer exists in the codebase. The code was restructured - session logic now lives in prompt.ts and processor.ts.
