fix(ci): replace broken conda workflow with pip + CLI build validation

[alfredo-petri]

Problem

.github/workflows/python-package-conda.yml references environment.yml (line 23) which does not exist in the repository. Every push triggers a failing CI job.

Additionally, there was no CI validation for the CLI package, so regressions in the TypeScript build or npm packaging could go undetected until a user tries to install.

Fix

Python job:

• Remove conda dependency; use pip install flake8 directly
• Scope lint to src/ui-ux-pro-max/scripts/ (the actual source)
• Add smoke test: run search.py with a real query to confirm the script is importable and functional

New cli-build job:

• Uses oven-sh/setup-bun@v2 (official Bun action)
• bun install + bun run build + npm pack --dry-run to catch packaging regressions

Summary: I’m blocking this PR from the cron-safe maintainer lane because it is now stale against current main and reintroduces an obsolete CI file.

Decision: blocked / needs rebase or close

Evidence:

• Current main no longer has .github/workflows/python-package-conda.yml; the repository now has .github/workflows/release.yml from merged PR feat(release): add semantic release automation #375.
• This PR still modifies .github/workflows/python-package-conda.yml, so merging it would add back a workflow path that no longer exists on main.
• The same CI/release area also overlaps PR feat: release workflow with SHA256 checksums + fix Python CI #349 and the merged semantic-release workflow, so the final desired CI shape needs to be based on the current workflow state, not the pre-feat(release): add semantic release automation #375 file.

Next step: please rebase on current main and retarget the useful part only. If the goal is still a Python script smoke/lint job, add it as a new, clearly named workflow or fold it into the current workflow strategy without resurrecting python-package-conda.yml. If the release workflow already covers the intended CLI build validation, this PR can be closed as superseded.
