fix(ci): support fork PRs in Claude Code Review workflow

Browse source 
claude-code-action fetches branches by name from origin, which fails
for fork PRs since the branch only exists on the fork remote. Work
around by detecting fork PRs and temporarily pushing the branch to
origin before the action runs, then cleaning up afterwards.

Also changed trigger from automatic (every push) to on-demand only
(label "claude-review" or comment "@claude" / "/review").
