chore: update n8n to 2.8.3 (#603)
* chore: update n8n to 2.8.3 and bump version to 2.35.3 - Updated n8n from 2.6.3 to 2.8.3 - Updated n8n-core from 2.6.1 to 2.8.1 - Updated n8n-workflow from 2.6.0 to 2.8.0 - Updated @n8n/n8n-nodes-langchain from 2.6.2 to 2.8.1 - Fixed node loader to bypass restricted package.json exports in @n8n/n8n-nodes-langchain >=2.9.0 (resolves via absolute paths) - Fixed community doc generator for cloud LLMs: added API key env var support, switched to max_completion_tokens, auto-omit temperature - Rebuilt node database with 1,236 nodes (673 n8n-nodes-base, 133 @n8n/n8n-nodes-langchain, 430 community) - Refreshed community nodes (361 verified + 69 npm) with 424 AI summaries - Updated README badge with new n8n version and node counts - Updated CHANGELOG with dependency changes Conceived by Romuald Członkowski - https://www.aiadvisors.pl/en 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fix: update documentation-generator tests for max_completion_tokens - Updated test assertions from max_tokens to max_completion_tokens - Updated testConnection token limit expectation from 10 to 200 - Added temperature to test config to match new configurable behavior Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> --------- Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
