Setup commit for the new generator CLI.
Added stubs for the current .go files. Added cobra, libopenapi, and their dependencies to the LICENSE-3rdparty file.
* [1.4] Add a github workflow for build + vet * [1.5] Add make command to build/test the generator * [1.6] Create testdata/fixtures with README * root formatting fixes * updated 1.4 to any branch and added go depencency files to paths
Added enums : - ArtifactKind - SchemaKind - IdStrategy Added structs: - Spec - Operation - Schema - Artifact - TrackingFieldMetadata - various other supporting structs...
* [TFgen] Added a identifier translator to match the goSDK The translator will transform the OAS snake_case names into the equivalent PascalCase that are used in the go SDK. Removed internal ticket names. * [TFgen] Added .gitignore
* [TFgen] Added a parser to load the OAS Added the parser's test data do `testdata/parser` * [TFgen] Added $ref cycle detection * [TFgen] Fail fast on circular $refs and wire --max-depth LoadSpec now resolves the component schema graph before enumerating: a circular $ref returns a typed *RefCycleError naming the offending ref, and expansion past --max-depth returns a depth error. The --max-depth flag is now wired through the generate command. * [TFgen] Added -race and -cover to the `make tfgen-test` command * [TFgen] (Nit) Addressed some minor concerns - Added better fixture coverage for allOf / anyOf - Added custom error for when max depth is reached in cycles.go
…tection (#3853) * Implement tracking-field decoder + duplicate artifact name detection * Fixed potential errors with missing skip values. * Support for ignoring duplicates if they have different kinds. * comment/contracts cleanup * removed redundant testing while keeping the same coverage
* [TFgen] Added a report structure Added a report structure for after run reports. This will be used by CI and may be used by other tools downstream. * [TFgen] Added tests for the reporting structure * [TFgen] Started wiring the reporter Set initial values for the run report in the generate command. The rest of the content should be filled by the actual generation. * [TFgen] Fix empty generator_version and gofmt the report layer cmd.Version is empty on the generate subcommand: cobra does not propagate Version from the root command, so the report's generator_version field was always "". Read it from cmd.Root().Version, where main.go stamps it. Also gofmt the RunReport and Spec struct literals (value alignment, stray blank lines) and fix a doc-comment typo in report.go.

This will prevent the generator-v2 dependencies flying under the radar * [TFgen] (CI) Added 3rd party licenses used in tfgen The License check was previously not run in the generator. Now that is is I have updated the file to add the used licences.

Summary
Introduces
.generator-v2/, a new standalone Go module that will replace the hand-written Terraform resource/data source authoring workflow. The generator reads the Datadog OpenAPI Specification, respects ax-datadog-tf-generatortracking field, and emits Go source code using the Datadog go-sdk.This PR adds the module skeleton only:
