feat: add LSP server, VSCode + DataGrip extensions, release infra, autofix

- pkg/lsp: JSON-RPC 2.0 LSP server (formatting, diagnostics, codeAction quick-fixes)
- cmd/pgtidy: lsp and config subcommands
- pkg/diagnostics: TextFix struct for byte-range autofixes
- pkg/lint: MIG001/MIG003 autofixes, ApplyFixes helper, --fix flag on lint command
- editors/vscode: TypeScript extension with LanguageClient, showVersion/showConfig/formatDocument commands, logo
- editors/datagrip: Gradle JetBrains plugin via LSP4IJ, pluginIcon
- .goreleaser.yaml, .github/workflows: CI + release pipeline
- Makefile: snapshot, release, vscode-compile, vscode-package targets
- go.mod + all imports: module path updated to git.warky.dev/wdevs/pgtidy
- assets: logo files (256px, 128px, 1024px, ico)
