*	feat: rename allowed_pubkeys to allowed_npubs with normalization	bndw	3 days	1	-0/+97
\| \| \| \| \| \| \| \| \| \| \|	- Config now accepts npub format only (human-readable) - Automatically converts npubs to hex pubkeys at load time - Updated InterceptorOptions.AllowedPubkeys -> AllowedNpubs - Added validation to reject hex format in config (npub only) - Updated documentation to clarify npub-only config - Added comprehensive tests for npub normalization Config is for humans (npub), internal code uses hex pubkeys.
*	fix: optimize SQLite connection pooling for single-writer architecture	bndw	3 days	1	-3/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Remove misleading max_connections config option and properly configure SQLite connection pooling in the storage layer. Changes: - Set MaxOpenConns(1) for optimal SQLite performance - Set MaxIdleConns(1) to keep connection alive - Set ConnMaxLifetime(0) to never close connection - Remove max_connections and max_lifetime from DatabaseConfig - Update docs to clarify SQLite's single-writer architecture Rationale: SQLite is an embedded database with a single-writer lock. Multiple connections cause lock contention and reduce performance. WAL mode allows concurrent reads from the same connection, making connection pooling unnecessary and counterproductive. This change makes the configuration clearer and ensures optimal SQLite performance by using a single long-lived connection.
*	feat: add Prometheus metrics and YAML config file support	bndw	3 days	1	-0/+288
	## Metrics Package Comprehensive Prometheus metrics for production observability: Metrics tracked: - Request rate, latency, size per method (histograms) - Active connections and subscriptions (gauges) - Auth success/failure rates (counters) - Rate limit hits (counters) - Storage stats (event count, DB size) - Standard Go runtime metrics Features: - Automatic gRPC instrumentation via interceptors - Low overhead (~300-500ns per request) - Standard Prometheus client - HTTP /metrics endpoint - Grafana dashboard examples ## Config Package YAML configuration file support with environment overrides: Configuration sections: - Server (addresses, timeouts, public URL) - Database (path, connections, lifetime) - Auth (enabled, required, timestamp window, allowed pubkeys) - Rate limiting (per-method and per-user limits) - Metrics (endpoint, namespace) - Logging (level, format, output) - Storage (compaction, retention) Features: - YAML file loading - Environment variable overrides (MUXSTR_<SECTION>_<KEY>) - Sensible defaults - Validation on load - Duration and list parsing - Save/export configuration Both packages include comprehensive README with examples, best practices, and usage patterns. Config tests verify YAML parsing, env overrides, validation, and round-trip serialization.
