`Semble`: agent code search with **98%** fewer tokens than `grep`

When agents miss code, grep burns context fast. Semble gives local CPU search with MCP support, worth testing on large repos now.

• —Hybrid retrieval combines static potion-code-16M embeddings, BM25, RRF, and code-aware reranking; no API key or GPU required.
• —Benchmarks cover about 1,250 query/document pairs, 63 repos, and 19 languages, giving better signal than a toy demo.
• —Claims 250ms typical repo indexing and 1.5ms CPU queries; large monorepos still need local validation.
• —MCP support targets Claude Code, Cursor, Codex, and OpenCode, so setup can replace noisy grep-style agent searches.
