fix: MMR default disabled, tie-break null guard, correct docs URL
- DEFAULT_MMR_CONFIG.enabled = false (opt-in, was incorrectly true)
- Tie-break: handle bestItem === null so first candidate always wins
- CHANGELOG URL: docs.clawd.bot → docs.openclaw.ai
- Tests updated to pass enabled: true explicitly where needed

feat(memory): Add opt-in temporal decay for hybrid search scoring
Exponential decay (half-life configurable, default 30 days) applied
before MMR re-ranking. Dated daily files (memory/YYYY-MM-DD.md) use
filename date; evergreen files (MEMORY.md, topic files) are not
decayed; other sources fall back to file mtime.
Config: memorySearch.query.hybrid.temporalDecay.{enabled, halfLifeDays}
Default: disabled (backwards compatible, opt-in).

feat(memory): Add MMR re-ranking for search result diversity
Adds Maximal Marginal Relevance (MMR) re-ranking to hybrid search results.
- New mmr.ts with tokenization, Jaccard similarity, and MMR algorithm
- Integrated into mergeHybridResults() with optional mmr config
- 40 comprehensive tests covering edge cases and diversity behavior
- Configurable lambda parameter (default 0.7) to balance relevance vs diversity
- Updated CHANGELOG.md and memory docs
This helps avoid redundant results when multiple chunks contain similar content.
