[Code Quality] Fix context.Background() in pkg/parser/remote_workflow_spec.go to honour compile cancellation

[github-actions]

Description

pkg/parser/remote_workflow_spec.go hard-codes context.Background() for three network calls (downloadFileFromGitHub / resolveRefToSHA at lines 91, 93, 156), even though these calls execute during the compilation pipeline where the caller holds a live, cancellable context. When a user presses Ctrl+C, compilation continues at these network steps until they time out.

A TODO comment at line 71 already acknowledges this gap.

Suggested Changes

• Pass a context.Context parameter through downloadFileFromGitHub and resolveRefToSHA
• Replace context.Background() at lines 91, 93, and 156 with the propagated context
• Update all callers that invoke these functions to pass their existing context

Files Affected

• pkg/parser/remote_workflow_spec.go (lines 71, 91, 93, 156)
• Callers of downloadFileFromGitHub / resolveRefToSHA in the parser package

Success Criteria

• No context.Background() calls remain inside remote_workflow_spec.go (except legitimate entry-point anchors)
• Cancelling a compile via Ctrl+C also cancels in-flight remote workflow fetches
• All existing tests pass

Priority

High — remote fetches during compilation are fully uncancellable; a TODO already marks this as known debt
