feat(capitalize): merge /close into /capitalize + TODO reconcile

Two-mode capitalize: default pre-wipe flush, --ritual adds the 3-question
end-of-session reflection (now deduped, unlike legacy /close). New STEP 2B
reconciles .claude/tasks/TODO.md — PASS A done-detection (only on an
unambiguous task<->commit map), PASS B explicit-only capture with an
anti-noise filter (never track commit/deploy/push/release/tag) and BDR
routing for orientation directives. STEP 3 gate gains a separate TODO block;
journal/handoff report TODO ops. /close becomes a thin alias for
/capitalize --ritual (zero duplicated logic).

Built via superpowers:writing-skills TDD: RED baseline (no skill) folded a
push/tag parasite into the TODO, invented a subtask, and wrote with no gate;
GREEN re-run on the same fixture stops at the gate, drops both dups (footer
shows existing IDs), logs one learning, checks only the cleanly-done task,
ignores the parasite, and routes the GraphQL directive to BDR.
