ci(claude-review): Use tracking comment summary

Review runs can end without posting anything to the PR, leaving no
visible record that the review happened (upstream issue
anthropics/claude-code-action#1087, still open with no input-level
fix). Enable `track_progress: true` so the action forces tag mode and
maintains a tracking comment on the PR: the comment is created before
the model runs and is finalized with the outcome and a job link even
if the model fails to follow the prompt, a stronger guarantee than a
prompt-driven `gh pr comment` instruction.

Tag mode's default prompt already directs the model to write its
review into the tracking comment, so instructing it to post a
separate summary comment would duplicate the same content (the
tracking comment carrying a full review is observable in the wild,
e.g. aws/secrets-store-csi-driver-provider-aws#629 runs this same
pattern). Keep only the content requirement in the prompt: when there
are no issues, the summary must state specifically what was reviewed
and verified rather than a bare "no issues found" — the false sense
of security that motivated switching review methodologies.
