ci: address QA — fix skip cascade, add packaging guard, sentinel for release-please bot

Addresses @runpod-Henrik (PASS WITH NITS) and Copilot review on PR #345.

Henrik #3 / Copilot inline ci.yml:50 — skip cascade
- Previously `pre-check.if` skipped on release-please bot PRs, and
  `quality-gates needs: [pre-check]` cascaded to skip too, leaving any
  release-please PR that touched non-metadata files with zero CI signal.
- Drop the workflow-level `paths-ignore` (it interacted badly with branch
  protection's required-check semantics anyway) and instead put explicit
  `if: !startsWith(github.head_ref, 'release-please--')` on pre-check,
  quality-gates, packaging-guard, and build. Symmetric, auditable.

Henrik #1 + #6 — branch-protection compatibility (release-please bot PRs)
- Add `release-please-sentinel` job with matching matrix + name "Quality
  Gates" so it produces the same "Quality Gates (3.10)"…"(3.13)" check
  names that branch protection requires, but auto-passes. Branch
  protection on main can now require those checks without admins having
  to either loosen the rule or hand-craft an external sentinel workflow.

Henrik #2 — PR-time wheel build is dropped
- Reintroduce build on PRs but gated by `packaging-guard` job that
  inspects `git diff` against the PR base. Build runs when:
    - pyproject.toml / Makefile / MANIFEST.in / scripts/validate-wheel.sh
      changed, OR
    - any new non-Python file was added under src/ (data files need
      explicit package-data inclusion or they're silently dropped).
- Push to main always builds.

Henrik #4 — `make dev` entry-point sanity check
- Verified locally: `rm -rf .venv && make dev && .venv/bin/flash --version`
  prints "Runpod Flash CLI v1.16.0". `uv sync` registers the entry point
  for the workspace project; the dropped `uv pip install -e .` was
  redundant. No code change needed.

Henrik #5 / Copilot Makefile:108 — misleading "plain output" comment
- Rewrite the comment block above `quality-check`. The aliases do NOT
  produce plain output -- local invocations see GitHub Actions
  annotation markers (::group::, --output-format=github) which are
  cosmetically noisy but functionally inert. Comment now reflects this.

Henrik misc nit — e2e.yml `unit-tests` job removal
- Add a leading comment on the `e2e` job explaining why the duplicate
  unit-tests job was dropped, so a future maintainer doesn't re-add it
  thinking it was lost by accident.
