[Code Quality] Extensive `any` usage bypasses TypeScript strict mode throughout codebase

[coderabbitai]

Summary

Despite tsconfig.json enabling strict: true, any is used pervasively across core modules, negating most type-safety benefits.

Key Occurrences

File	Usage
src/config/manager.ts	validateConfig(config: any), configToSave as any
src/agents/base.ts	protected config: any
src/agents/types.ts	AgentConfig is { [key: string]: any }
src/beads/memory.ts	private db: any
src/git/collector.ts	private git: any, multiple casts
src/pocketflow/workflow.ts	private config: any
src/llm/adapter.ts	LLMConfig has [key: string]: any index signature

Impact

• Runtime type errors are not caught at compile time
• IDE auto-complete and refactoring tools cannot reason about these values

Recommended Fix

• Type db as Database from better-sqlite3
• Type git as SimpleGit from simple-git
• Replace AgentConfig placeholder with concrete per-agent config interfaces
• Remove the [key: string]: any index signature from LLMConfig
