chore: bump version to 2.22.9 (#395)

* chore: bump version to 2.22.9

Updated version number to trigger release workflow after n8n 1.118.1 update.
Previous version 2.22.8 was already released on 2025-10-28, so the release
workflow did not trigger when PR #393 was merged.

Changes:
- Bump package.json version from 2.22.8 to 2.22.9
- Update CHANGELOG.md with correct version and date

* docs: update n8n update workflow with lessons learned

Added new fast workflow section based on 2025-11-04 update experience:
- CRITICAL: Check existing releases first to avoid version conflicts
- Skip local tests - CI runs them anyway (saves 2-3 min)
- Integration test failures with 'unauthorized' are infrastructure issues
- Release workflow only triggers on version CHANGE
- Updated time estimates for fast vs full workflow

This will make future n8n updates smoother and faster.

* fix: exclude versionCounter from workflow updates for n8n 1.118.1

n8n 1.118.1 returns versionCounter in GET /workflows/{id} responses but
rejects it in PUT /workflows/{id} updates with the error:
'request/body must NOT have additional properties'

This was causing all integration tests to fail in CI with n8n 1.118.1.

Changes:
- Added versionCounter to excluded properties in cleanWorkflowForUpdate()
- Tested and verified fix works with n8n 1.118.1 test instance

Fixes CI failures in PR #395
