Release v0.1.14

Highlights:
- Adds index-aware known-entity extraction so seeded project names, internal codenames, and single-segment CamelCase entities can be propagated without loosening first-mention extraction.
- Stores embeddings as float32 blobs going forward, with automatic migration from official legacy float64 embedding blobs.
- Fixes Claude Code setup from $HOME by detecting the .claude user-global collision and writing absolute hook commands.

Validation:
- go build -o mnemon .
- make test
- go test ./... in a clean worktree
