fix(memory): accept extra digest fields

[Hardik180704]

Issue

Fixes #12674

Context

Memory digest generation can return valid JSON containing useful model-specific fields in addition to topic and summary. The digest schema rejected the entire response when those extra keys were present, causing a memory.error event and fallback behavior even though the required digest fields were valid.

Implementation

Allow the digest-only schema to use Zod's default unknown-key handling. Additional fields are accepted and stripped from the parsed result, while topic and summary retain their existing validation and defaults. The stricter schemas used for typed memory operations remain unchanged.

A regression test covers the reported next_step and blockers fields and verifies that only topic and summary reach downstream code.

Screenshots / Video

N/A — this is a parser behavior fix with no visual changes.

How to Test

Manual/local verification

• Agent-executed: bun test test/capture.test.ts in packages/kilo-memory — 29 passed.
• Agent-executed: bun test in packages/kilo-memory — 165 passed.
• Agent-executed: bun run typecheck in packages/kilo-memory — passed.
• Agent-executed: bun run lint at the repository root — passed with 0 errors and existing warnings only.

Reviewer test steps

1. Parse a digest response containing valid topic and summary fields plus additional keys such as next_step and blockers.
2. Confirm parsing succeeds.
3. Confirm the parsed result contains only topic and summary.
4. Confirm typed memory-operation schemas still reject unsupported fields.

Blocked checks and substitute verification

• None.
