What

Adds semantic_search() to MnemosyneArchive backed by the existing HolographicLinker tokenizer and Jaccard similarity — no new dependencies.

How it works

Tokenizes the query using HolographicLinker._tokenize() (same tokenizer used during ingestion)
Scores each entry by Jaccard similarity between query tokens and entry tokens (title + content + topics)
Link-connectivity boost — entries with more inbound links get up to +20% score boost
Graceful fallback — if no entries meet the similarity threshold, falls back to search() (keyword match)

CLI

mnemosyne search --semantic "some query"

Tests

5 new tests covering: basic results, link boost ranking, keyword fallback, empty archive, and semantic vs keyword relevance comparison. All 22 tests pass.

Implements semantic_search() on MnemosyneArchive that scores entries by
Jaccard similarity between query tokens and entry tokens (using the linker's
tokenizer), with a connectivity boost for entries with more inbound links.
Falls back to keyword search when no entries meet the similarity threshold.

CLI updated: mnemosyne search --semantic flag routes to semantic_search().

Fixes #1223
