Migrate from Makefile to Justfile for command management, updating CI workflows, pre-commit hooks, and documentation accordingly.

• Command Management:
  • Replace Makefile with Justfile for build and development commands.
  • Remove Makefile and associated makefiles.
• CI Workflows:
  • Update .github/workflows/build-rust.yml, .github/workflows/rust-unit.yml, .github/workflows/rust.yml, and .github/workflows/typescript-integration.yml to use just commands instead of make.
• Pre-commit Hooks:
  • Update .pre-commit-config.yaml to use just fmt and just format-ts-sdk for formatting.
• Documentation:
  • Modify README.md, CLAUDE.md, and crates/lib/src/metrics/README.md to reflect new just commands for installation, building, and testing.

  Updated the metrics documentation to use 'just run-metrics'; ensure that the underlying justfile target matches the intended behavior.
• Reason this comment was not posted:
  Comment did not seem useful. Confidence is useful = 0% <= threshold 50% The comment is asking the author to ensure that the underlying justfile target matches the intended behavior. This falls under asking the author to ensure something, which is against the rules.

  The new justfile is comprehensive and well organized, covering build, test, service run, SDK management, docs, coverage, and release processes.

11. Makefile:1

  Legacy Makefile has been removed along with its auxiliary makefiles, which is appropriate given the migration to just.

Since this requires a new prereq for ppl using our commands, wdyt about adding something like this to readme under local dev?

Local development and testing use [Just](https://github.com/casey/just) as a build and development tool--make sure to install it before running any commands.
