Module lint 

Lint Engine for Seq

A clippy-inspired lint tool that detects common patterns and suggests improvements. Phase 1: Syntactic pattern matching on word sequences.

Architecture

• LintConfig - Parsed lint rules from TOML
• Pattern - Compiled pattern for matching
• Linter - Walks AST and finds matches
• LintDiagnostic - Output format compatible with LSP

Known Limitations (Phase 1)

• No quotation boundary awareness: Patterns match across statement boundaries within a word body. Patterns like [ drop would incorrectly match [ followed by drop anywhere, not just at quotation start. Such patterns should be avoided until Phase 2 adds quotation-aware matching.
