[Medium] Add config schema validation for new experimental fields

[randomm]

Problem

New config fields lack Zod validation:

• remory_enabled
• remory_persist_context
• remory_persist_thinking
• remory_inject_context
• remory_max_length
• remory_search_limit
• background_tasks
• max_background_tasks
• context_window_percent

Solution

Add Zod schemas with:

1. Type validation
2. Bounds checking (e.g., context_window_percent 0-1)
3. Sensible defaults

Files

• packages/opencode/src/config/config.ts

Closing - config schema validation for all experimental fields is already implemented in packages/opencode/src/config/config.ts (lines 1089-1139). All fields have Zod schemas with type validation, bounds checking, and sensible defaults:

• remory_enabled, remory_persist_context, remory_persist_thinking, remory_inject_context: boolean with defaults
• remory_max_length: 100-2000 chars, default 700
• remory_search_limit: 1-20, default 5
• background_tasks: boolean, default true
• max_background_tasks: int >= 0, default 0
• context_window_percent: 0.1-1.0, default 0.8
