chore(kiloclaw): upgrade openclaw 2026.4.9 → 2026.4.15

[iscekic]

Summary

• Bump OpenClaw version pin from 2026.4.9 to 2026.4.15 (5 releases, v2026.4.13 never published)
• 374 changelog entries analyzed — zero code-level impact on KiloClaw (all CLI flags, config keys, env vars, plugin interfaces unchanged)
• Increment Dockerfile build cache bust (v66)
• Clean up stale 2026.4.5 version references in .dev.vars.example and e2e/docker-image-testing.md

Notable upstream changes (no KiloClaw action needed)

• Codex provider bundled
• Active Memory plugin
• Plugin loading narrowed to manifest-declared needs
• Default Anthropic model bumped to Opus 4.7 (overridden by our explicit model setting)
• Dreaming storage mode default inline → separate (we don't set this field)
• Unknown-tool stream guard enabled by default (beneficial)
• 51 security fixes

Test plan

• pnpm typecheck passes
• pnpm test passes (1563 tests)
• pnpm lint passes
• Docker build succeeds (sed patch for DISCOVERY_TIMEOUT_MS self-validates)
• Push to dev via push-dev.sh kiloclaw-machines-dev
• Fresh instance boots and completes bootstrap
• Existing instance restarts cleanly
• Plugins load (kiloclaw-customizer, Stream Chat)
• WebSocket proxy works end-to-end
