Change the review fan-out from one subagent per commit to one subagent per
lens, each reviewing every commit through a single perspective. Four base
lenses (correctness/memory safety, lifetimes/concurrency, security, API/style)
always run; the orchestrator skims the diff and adds 1-3 PR-specific lenses
(e.g. a DNS protocol lens for resolved changes). A single generalist reviewer
tended to converge on one finding on large diffs; focused lenses dig deeper.
Commits are reviewed in chronological order via a commit-order.txt manifest,
since the SHA-named worktree dirs don't sort chronologically.
