Brain memories can now be stored in a separate database, co-located
with Qdrant vectors on the homelab. Defaults to the app's main DB
when no BRAIN_DB_* env vars are set (zero-config for existing installs).
- Add brain.database config with BRAIN_DB_* env var support
- Register 'brain' database connection in Boot.php
- Set BrainMemory model to use 'brain' connection
- Update BrainService transactions to use brain connection
- Update migration to use brain connection, drop workspace FK
(cross-database FKs not supported)
- Add migration to drop FK on existing installs
- Update default URLs from *.lthn.lan to *.lthn.sh

Adds a private http() helper that wraps Http::timeout() with
conditional withoutVerifying() for self-signed .lan certs behind
Traefik. Boot singleton auto-detects .lan URLs at construction.

Make embedding model swappable via BRAIN_EMBEDDING_MODEL env var.
Switch default from nomic-embed-text to embeddinggemma (Gemma 3
based, 2x better cluster separation in benchmarks).
Default Ollama URL now points to ollama.lan (Linux homelab GPU).

- Move BrainMemory::create() inside BrainService::remember() for
full atomicity (DB + Qdrant in single transaction)
- Add forWorkspace() scope to recall() MariaDB query (tenant isolation)
- Wrap forget() in DB::transaction (MariaDB first, then Qdrant)
- Check qdrantDelete() response and log warnings on failure
- Validate embed() response is a non-empty array
