* fix(agent): persist /model selection to .env, TOML, and DB
The /model command only wrote selected_model to the DB and config.toml,
but env vars from ~/.ironclaw/.env (e.g. NEARAI_MODEL) have the highest
priority in LlmConfig::resolve_model(). The .env value was never
updated, so it always shadowed the new model on restart.
Now persist_selected_model updates all three persistence layers:
1. The backend-specific model env var in ~/.ironclaw/.env (only if the
var already exists, to avoid injecting new vars)
2. The config.toml file (created if absent, since TOML > DB priority)
3. The DB settings table (for completeness)
Also adds diagnostic logging when the DB store is unavailable.

* fix(agent): address PR review — backend from deps, exact .env match
Review feedback:
- Use resolved llm_backend from AgentDeps instead of re-reading from
disk/env (fixes DB-only backend detection, eliminates redundant I/O)
- Match .env var with exact "KEY=" prefix and skip commented lines
(prevents false matches on NEARAI_MODEL_VERSION etc.)
- TOML is now loaded once (no double-read for backend + model update)
