feat(agent): add pagination and smart collapsing to container list tool

Large directories like node_modules/.venv could return thousands of entries,
wasting tokens and causing timeouts. Add offset/limit pagination to ListDir
RPC and collapse heavy subdirectories (>50 items) into summaries in recursive
mode. Collapsing runs at the bridge layer before pagination so the page window
reflects the collapsed view.
