feat(jin-frame): validateStatus in FrameOption, safeParse fix, PUT/PATCH multipart, comment translations

[imjuni]

Summary

• validateStatus in FrameOption: validateStatus can now be set at the decorator level (@Post, @Get, etc.) and will be applied to all _execute() calls. Resolution priority: _execute() option > FrameOption decorator > default (response.ok).
• safeParse fix: safeParse now returns the raw string instead of undefined when JSON.parse fails, fixing plain-text (boolean, string, number) API responses.
• PUT/PATCH multipart/form-data: Extended multipart/form-data support to include PUT and PATCH methods (was POST-only).
• Korean comment translations: All remaining Korean source comments translated to English.
• Naming convention docs: Added naming convention documentation pages (EN/KO) and registered in sidebar.
• Axios removal from docs: Replaced all Axios references in docs with native fetch equivalents.
• OAuth2 remnant removed: Removed refreshToken from AuthorizationData.
• Version bumps: 5.0.0 → 5.0.1 → 5.0.2 → 5.0.3

Test plan

• All 482 tests passing
• New tests for validateStatus in FrameOption (2 cases)
• New tests for safeParse (8 cases)
• New tests for PUT/PATCH multipart/form-data (2 cases)
