Subject: [PATCH 1/9] UN-2894 Fix n8n cloud review issues

- Remove dependency overrides from package.json
- Remove prepublishOnly script, add validate script instead
- Add pairedItem linkage to all returnData.push() calls
- Replace helpers.request() with helpers.httpRequestWithAuthentication()
- Update LLMWhispererApi credentials to use unstract-key header
- Add build:dev script for fast development builds
- Update workflows to use validate script for comprehensive checks
- Update package-lock.json

All blocking issues from n8n cloud review have been addressed.

Subject: [PATCH 2/9] refactor: separate audit check from validation script

- Add dedicated 'audit' script for security checks with high severity threshold
- Remove audit from 'validate' script to allow independent execution
- Update package-lock.json to reflect current dependency tree

Subject: [PATCH 4/9] refactor: remove httpbin credential tests per n8n review

- Remove test property from all three credential classes:
  - LLMWhispererApi
  - UnstractApi
  - UnstractHITLApi
- Remove unused ICredentialTestRequest import
- httpbin tests did not actually validate credentials (would pass with any value)
- Following n8n recommendation to remove rather than use fake validation endpoints

Addresses n8n community node review feedback.

Subject: [PATCH 5/9] fix: correct credential reference in authenticate blocks

- Fix UnstractApi to use {{$credentials.apiKey}} instead of literal 'apiKey'
- Fix UnstractHITLApi to use {{$credentials.HITLKey}} instead of literal 'apiKey'
- Previous implementation sent literal string "Bearer apiKey" instead of actual token
- This bug was introduced in PR #17 along with httpbin tests

These authenticate blocks are required for httpRequestWithAuthentication to work correctly.

Subject: [PATCH 6/9] fix: add explicit Authorization headers to work around
 n8n formData bug

- Add explicit Authorization header to Unstract node POST request
- Add explicit Authorization header to status polling GET requests
- Extract apiKey from credentials to use in headers
- Works around known n8n bug where httpRequestWithAuthentication doesn't
  properly add auth headers when formData is present (Issue #18271)
- Still uses httpRequestWithAuthentication to satisfy n8n review requirements
- Restores working pattern from commit 845c15c while keeping httpRequestWithAuthentication

This fixes 'Bad request' errors caused by missing Authorization headers.

Subject: [PATCH 7/9] fix: resolve n8n Cloud compatibility issues across all
 nodes

This commit addresses multiple issues found during n8n Cloud review:

**Unstract node:**
- Add HTTP 422 handling for status polling (API uses 422 to indicate "still executing")
- Use helpers.httpRequest() for status checks with manual Authorization header
- Add comprehensive logging with request/response details

**UnstractHitlPush node:**
- Implement manual multipart/form-data construction (n8n Cloud requirement)
- Add HTTP 422 handling for status polling
- Fix response parsing to handle already-parsed JSON from httpRequestWithAuthentication
- Add comprehensive logging for debugging

**LLMWhisperer node:**
- Fix response parsing issues (httpRequestWithAuthentication returns parsed JSON, not strings)
- Remove incorrect HTTP status check that was comparing job status to HTTP status code
- Add proper validation for required whisper_hash field
- Add comprehensive logging throughout the workflow

**Credentials:**
- Remove trailing whitespace for code quality

All nodes now properly handle:
1. Response parsing from httpRequestWithAuthentication
2. Status polling with appropriate error handling
3. Manual multipart form construction where required for n8n Cloud

Subject: [PATCH 8/9] chore: remove debug logging from all nodes

Removed debug logging statements that were added for troubleshooting:
- LlmWhisperer: removed 6 logger statements
- Unstract: removed 15 logger statements
- UnstractHitlPush: removed 10 logger statements

All nodes now have clean code without debug-level logging.
