ci: enable claude-code/opus:max (max-thinking) reviewer (#6)

Adds claude-code/opus:max to the dogfood swarm and pins to :sha-c342bdb
(which has the :thinking parse). Claude Code lineup is now sonnet + opus +
opus:max. All three ran end-to-end on this PR's own review; 0 findings
(clean PR + the telemetry fix suppressing phantom clean-verification
findings — working as intended).
