CLI bug: issue label remove errors 'not found' for labels attached to the issue

Bug: issue label remove rejects labels that ARE on the issue

Reproduction

huly issue label add HULY-4 --label security --label publication --label telemetry
huly issue label remove HULY-4 --label publication

Observed

✗ error [2]  label publication not found

But huly issue get HULY-4 --json | jq .labels returns ["security","publication","telemetry"] — the label IS attached.

Expected

The label is removed from the issue, identical to how issue label add works.

Hypothesis

label remove is probably looking up the label in a workspace-level tracker:class:IssueLabel catalog first (since findAll on that class also times out — possible related symptom) and bailing out if it cannot resolve a catalog entry by name, even though the label exists on the issue.

Workaround

Used huly issue update <ref> --unset labels to clear all, then label add to re-apply the desired subset. Destructive (wipes everything) — not safe when only some labels should be removed.

Acceptance Criteria

• label remove succeeds when the label is attached to the issue, regardless of workspace catalog state.
• Or: error message explicitly says "label not in workspace catalog" so the user understands why it failed.
• Workaround for partial removal is documented if fix is non-trivial.
