Fabr 0.2.1 released

This release is primarily focused on improving external dependency resolution, along with some additional support for a broader range of codebases.

The next major release will be focused on improving build performance.

@fabr-build/core:

• include paths may now glob (include lib/**/*.fabr;).
• Cap maximum concurrent connections + executing processes.
• New fetch download source for arbitrary http/https fetching.
• Enable automatic extraction and traversal of archive files.
• Add support for bash extended globs (eg !(expr) ).
• Add support for default targets and default target properties.
• Add support for package renaming using -> rename syntax.
• Add repository_group target for adding multiple scoped repositories and package overrides.
• Detect a plugin that loads its own nested copy of @fabr-build/core (a broken install) and report it clearly.
• Allow rename from wildcard to fixed name (if matched once only)
• Fix: generate command names resolved incorrectly.
• Fix: remove excessive synchronous mkdirs
• Fix: sync targets being unavailable to other build steps.

@fabr-build/js:

• Add a jest compatibility test runner (JS_TEST_RUNNER = @fabr-build/js-tools/jest-runner;)
• Generated package.json now strips build-only fields (devDependencies, scripts, …) from an imported manifest, and emits array metadata (keywords, os, cpu) as JSON arrays.
• Add support for package aliases in external dependencies.
• Add resources (copied as-is) inputs to js_package.
• Add ability to use package members as bundle entry points (like scripts)
• Add ts/experimental_decorators + ts/emit_decorator_metadata flags and cover the rest of the strict flags.
• Emitting below es2015 now also automatically enables downlevelIteration
• Handle package resolution edge cases with missing specified versions.
• Make esModuleInterop: true by default; ts/no_es_module_interop to disable.
• Revise MVS resolution to drop the 'independent major versions' concept we accidentally imported from Go.
• Generate resolution repair lists on resolution failures.
• Readd es* flags as source version dependency flags.
• Drop lightningcss; esbuild now handles css modules directly.
• Fix TS source importing local references using full package path.
• Fix esbuild resolver erroring on survivable misses.
• Fix sass errors to report positions in the original sources via source maps.
• Fix assorted dependency resolution issues.
• Fix creating hardlinks in NPM publish tarballs (rejected by NPM)
