PR Review: Documentation Update for GameLift Support

Summary

This PR updates documentation across all language variants (EN, JA, KO, ZH-CN) to reflect the addition of GameLift support. The changes are documentation-only and accurately reflect the implementation already present in the codebase.

---

✅ Code Quality & Best Practices

Strengths:

• Consistency: All 4 language variants (English, Japanese, Korean, Chinese) are updated consistently
• Accuracy: Service count (69 → 70) and resource count (169 → 175) are mathematically correct
  • GameLift adds 1 service with 6 resources (+6)
  • This accounts for the increase from 169 to 175 resources
• Completeness: Updated all relevant locations:
  • Feature descriptions in README files
  • Documentation reference tables
  • Service documentation pages
  • Service alias tables

Verification:

• ✅ GameLift implementation exists in custom/gamelift/ with 6 resource types
• ✅ Registry entry confirmed in internal/registry/registry.go:270
• ✅ Service alias gl properly registered at line 135
• ✅ Display name "GameLift" registered at line 169
• ✅ GameLift resources listed: Fleets, Builds, Scripts, Game Sessions, Game Session Queues, Matchmaking Configurations

---

✅ Documentation Quality

Strengths:

• GameLift section placed in appropriate "Game Development" category
• Resources are clearly listed and match the actual implementation
• Alias gl follows the project's naming conventions
• Translations appear accurate across all language variants

Minor Observations:

• The Korean README.ko.md:114 shows "163 resources" in the table description, but this is being correctly updated to "175 resources" in the PR diff
• All other language variants are consistent

---

✅ Testing & Verification

Documentation-only changes:

• No code changes to test
• Documentation changes are straightforward text updates
• No risk of runtime issues

Recommendation:

• Consider verifying that the GameLift implementation is fully functional if it hasn't been tested yet
• Ensure the 6 GameLift resources work as expected with the TUI

---

✅ Security & Performance

No concerns:

• Documentation-only changes pose no security or performance risks
• No sensitive information exposed
• No code execution paths affected

---

🎯 Overall Assessment

Verdict: LGTM ✅

This is a clean, well-executed documentation update that:

1. Accurately reflects the codebase state
2. Maintains consistency across all language variants
3. Follows the project's documentation patterns
4. Contains no errors or discrepancies

Recommendation: Approve and merge
