fix(workflow-ui): clamp long tool descriptions in the tool picker - #392

Conversation
The shared cf-tool-picker rendered each tool's full catalog description. Catalog entries like apply_patch carry a multi-paragraph spec (~864px tall), so the node-overrides tools picker — which lists the whole host + MCP catalog — became unusable, dominated by description text. Clamp descriptions to 2 lines with a "show more" / "show less" toggle. Only descriptions long enough to actually be truncated (>140 chars or multi-line) get the clamp + toggle; short one-liners (echo, now) render in full as before. Per-tool expanded state, keyed by tool identifier. Benefits the agent-role editor too — it uses the same picker. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
