chore: simplify release flow and issue templates

[rubenmarcus]

Summary

• Remove beta npm tag logic from all release workflows — stable-only releases going forward
• Simplify issue templates (bug, config, feature) from 6-8 fields to 2-3 essentials
• Enable blank issues so users can bypass templates entirely

Changes

Release workflows

• release.yml: Removed npm dist-tag add ... beta line
• release-on-tag.yml: Always publish with --tag latest, removed prerelease detection
• prepare-release.yml: Stable-only version calculation, removed beta bump path
• stable-release.yml: Renamed to "Manual Release", removed beta changelog consolidation (~80 lines)
• package.json: Removed release:beta script

Issue templates

• bug_report.yml: 8 fields (6 required) → 5 fields (1 required)
• config_issue.yml: 8 fields (4 required) → 3 fields (1 required)
• feature_request.yml: 7 fields (3 required) → 2 fields (1 required)
• config.yml: blank_issues_enabled: true

Manual step after merge

Remove the stale beta npm dist-tag:

npm dist-tag rm ralph-starter beta

Test plan

• Verify YAML syntax is valid in all workflow files
• Create a test issue using each simplified template
• Verify next candidate-release PR creates a stable version release PR
• Run npm view ralph-starter dist-tags after removing beta tag
