ci: trigger Claude code review on /claude-review PR comments

[chongchonghe]

Description

Rework the two Claude GitHub Actions workflows following the official documentation. claude-code-review.yml now runs the code review on a manual trigger — a /claude-review comment on a PR — instead of the previous mix of workflow_dispatch, label, and comment triggers, and is aligned with the upstream anthropics/claude-code-action review template (progress tracking + inline review comments). claude.yml is brought back in line with the official starter template.

claude-code-review.yml:

• Trigger reduced to issue_comment + an if: guard that only fires on PR comments containing /claude-review (manual, opt-in review).
• Adopt the upstream review template: track_progress: true and claude_args --allowedTools for inline comments via mcp__github_inline_comment__create_inline_comment plus gh pr tooling.
• Fix PR-number reference: issue_comment events have no github.event.pull_request object, so the prompt now uses github.event.issue.number (which is the PR number for PR comments).
• Checkout the PR head (ref: refs/pull/${{ github.event.issue.number }}/head) so the review reads the PR's code, not the default branch (the default for issue_comment events).
• Drop the now-unneeded issues: write permission and the pinned model / max-turns args, matching the upstream template.

claude.yml:

• Realign with the official starter template; move actions: read into the job permissions block (replacing the old additional_permissions input) and drop the pinned model / max-turns args.

Note: because issue_comment workflows always run from the default branch, the new trigger behavior only takes effect after this PR merges to development.
