Real-time code feedback for pi — LSP, linters, formatters, type-checking, structural analysis & booboo

# Language Coverage

pi-lens supports **36+ languages** through dispatch runners and LSP integration.

Formatting uses a single selected formatter per file: explicit project config wins, otherwise pi-lens uses a smart default where supported, and config-first ecosystems do not autoformat without config.

Dispatch is diagnostics-oriented: automatic formatting and safe autofix happen in the post-write pipeline rather than through dispatch format-check runners.
