feat(script): add lazyclaudecode marketplace syncer with CC paths and filter

Forks sync-lazycodex-marketplace: reads .claude-plugin/plugin.json, writes
.claude-plugin/marketplace.json + plugins/omo, asserts sisyphuslabs/omo
identity, excludes src/test/tsconfig*/.omo from the shipped tree. RED->GREEN
test (6 pass).
