Disable automated Claude PR review (manual-only trigger)

[cpitzi]

Summary

Disables the automated Claude Code review that previously ran on every pull
request by switching the claude-code-review.yml workflow trigger from
pull_request to a manual workflow_dispatch. The workflow and this repo's
tailored review_prompt are retained, so the review can still be invoked on
demand and re-enabled later by restoring the pull_request trigger.

This is part of a fleet-wide change turning off automated Claude PR review
across the PitziLabs repositories. The Claude review was not a required status
check in any repository, so disabling it does not change merge gating; the
real CI checks are untouched.

Notes

• Only the workflow trigger changed — the job definition and review prompt are
  preserved.
• The interactive @claude responder (claude.yml) is intentionally left
  active; this change only affects the automated review.
