For linking of Angular packages we are using something more clever than what we are doing with `rules_nodejs`. Instead of maintaing complexity where we pre-link FESM bundles and somehow inject them into other Bazel bundling steps (with complex linker mappings), we pre-link as part of individual package postinstall steps, exposing the linked bundles via a NodeJS exports condition. This is possible vis this package/script: https://github.com/devversion/angular-linking Clearly this is not at a good location, but it's necessary right now to ship this code via npm because `rules_js` struggles to use pnpm extensions onto workspace 1st-party packages. Long-term we can either decide to keep it that way, move it into e.g. dev-infra repository, or we can explore shipping pre-linked bundles via APF. TBD.
Migrates all `ts_library` targets in `tools/` to use the `rules_js` `ts_project` rule.
Improves the `ts_project` interop to work with Esbuild bundling. Right now we can end up with multiple copies of the same source file. e.g. input might import from `@angular/cdk/testing` and end up with the version of `rules_nodejs` linker, while other imports to the native `ts_library` targets end up being mapped to their actual sources in the `bazel-bin`, and not inside `node_modules`
Migrates more `ts_library` targets to `rules_js`
