Add Log Analysis Pattern-Based Alert Rules

[maugauwi-hash]

Labels: enhancement, observability
Priority: Medium
Estimated Time: 2 hours

Description:
backend/src/log_analysis.rs presumably parses/aggregates logs, but there's no configurable rule engine to alert on specific log patterns (e.g., a spike in a particular error message) beyond generic error-rate thresholds.

Tasks:

• Add a pattern-matching rule configuration (regex or structured field match)
• Trigger alerts via incidents.rs when a pattern's occurrence rate exceeds a threshold
• Add tests for pattern matching and threshold-based alerting
• Document rule authoring in docs/log-format.md
