fix(.claude/EN): remove phantom file refs from README index

Follow-up to the agentkit consolidation merge. The README tree listing
referenced knowledge/reading-depth-ladder.md and knowledge/lie-detector.md,
but those documents were never created as standalone files — the
Reading-Depth-Ladder and Lie-Detector LD-1..5 both live inline in
CLAUDE-AGENT-PATTERN.md (§3 and §4 respectively).

Direct-to-default-branch since the consolidate PR is already merged.
