feat(treesitter): add native C runtime and 18-grammar compilation bridge - #143
Merged
Conversation
- Vendor modern Tree-sitter C runtime header and Go build tool (build_grammars.go) - Support parallel static compilation of 18 native grammars into libdiffmantic_grammars.a - Add Renovate configuration and GitHub Actions caching for native grammars - Replace Dependabot with Renovate for automated grammar version bumps
golangci-lint fmt walks ./... on the filesystem regardless of .gitignore. The grammars-native build step clones vendored grammar repos into native/bridge/grammars/ before the fmt step runs, so their Go example files were getting caught and failing the format diff check. Add --exclude-dirs native/bridge/grammars to skip those cloned files.

In golangci-lint v2, linters and formatters have separate exclusion blocks. Added linters.exclusions.paths and formatters.exclusions.paths to skip native/bridge/grammars, which is populated at build time by cloning vendored grammar repos and is not tracked by git.
