🐛 fix: resolve CI workflow issues

Fix three critical CI issues:

1. SWAG TOOL: Install swag before go generate

   - Adds 'Install swag' step to build-test job

   - Prevents 'command not found' errors

   - Ensures swagger docs can be generated

2. GO VET REDUNDANCY: Remove duplicate go vet

   - Removes go vet from lint-format job

   - Keeps go vet only in build-test job

   - Reduces CI execution time

3. WORKFLOW VALIDATION: Fix yamllint path

   - Updates validate-workflow.sh to use absolute paths

   - Fixes .yamllint.yaml file not found error

   - Makes path resolution more robust

These fixes address the root causes of:

- Job 350 failure (missing swag)

- Redundant validation (duplicate go vet)

- Workflow validation failures (wrong paths)

Tested locally and ready for CI.
