Problem

.goreleaser-jtk.yml uses homebrew_casks.alternative_names (lines 64-65), which is a GoReleaser Pro-only field. We use GoReleaser OSS (free), so it rejects the config immediately:

yaml: unmarshal errors:
  line 64: field alternative_names not found in type config.HomebrewCask

This was introduced in commit cbe3071 ("Make jtk the primary cask name with jira-ticket-cli as alternative").

Impact

Blocks all jtk releases. GoReleaser fails before building any binaries. Affected runs:

• jtk-v0.1.15 (run 21779452648)
• jtk-v0.1.16 (run 21780062966)

Fix

1. Remove alternative_names block from .goreleaser-jtk.yml
2. Add binary: jtk to the cask config (it's missing — cfl has it, jtk doesn't)
3. To provide the jira-ticket-cli alias, manually maintain a separate cask file in the homebrew-tap repo (separate issue)
