* feat: rename n8n_trigger_webhook_workflow to n8n_test_workflow with multi-trigger support
- Rename tool from n8n_trigger_webhook_workflow to n8n_test_workflow
- Add support for webhook, form, and chat triggers (auto-detection)
- Implement modular trigger system with registry pattern
- Add trigger detector for automatic trigger type inference
- Remove execute trigger type (n8n public API limitation)
- Add comprehensive tests for trigger detection and handlers
The tool now auto-detects trigger type from workflow structure and
supports all externally-triggerable workflows via n8n's public API.
Note: Direct workflow execution (Schedule/Manual triggers) requires
n8n's instance-level MCP access, not available via REST API.

* fix: prevent workflow validator from mutating node types
The validator was incorrectly mutating node types from full form
(n8n-nodes-base.*) to short form (nodes-base.*) during validation.
This caused deployed workflows to show "?" icons in n8n UI because
the API requires full form node types.
Also updated SplitInBatches detection to check both node type forms
since workflows may contain either format.

* fix: pin MCP SDK and Zod versions to prevent Zod v4 resolution
Fixes#440, #444, #446, #447, #450
Root cause: package.json declared `"@modelcontextprotocol/sdk": "^1.20.1"`
which allowed npm to resolve to SDK 1.23.0. That version accepts
`"zod": "^3.25 || ^4.0"`, causing npm to deduplicate to Zod v4.
SDK 1.23.0's `isZ4Schema()` function crashes when called with undefined,
which happens for plain JSON Schema objects.
Changes:
- Pin SDK to exact version 1.20.1 (removes ^ prefix)
- Pin Zod to exact version 3.24.1 (removes ^ prefix)
- Add CI workflow to verify fresh installs get compatible versions
The new CI workflow:
- Packs and installs package fresh (without lockfile)
- Verifies SDK is exactly 1.20.1
- Verifies Zod is NOT v4 (blocks 4.x.x)
- Runs weekly to catch upstream dependency changes
