Release v0.13.0

Atomic Split Commit - Intelligent Multi-File Change Grouping

New --split mode automatically groups staged changes into multiple logical atomic commits using LLM analysis. Also includes LLM Provider interface refactoring and error handling improvements.

Added

Atomic Split Commit Mode

• New gcop-rs commit --split groups staged files into logical atomic commits via LLM
• Interactive menu: Accept All / Edit in TOML editor / Regenerate / Regenerate with feedback / Quit
• Partial failure recovery: completed commits are preserved, remaining files re-staged
• Configurable via [commit] split = true in config or --split CLI flag

Split-specific Error Types

• SplitCommitPartial: reports completed/total groups on partial failure with recovery guidance
• SplitParseFailed: handles invalid LLM JSON responses with retry suggestions

Internationalization

• 21 new i18n strings for split commit UI, errors, and suggestions (en + zh-CN)

Changed

LLM Provider Interface Refactored

• New send_prompt(system, user, progress) as the core trait method
• Provider implementations only need send_prompt; high-level APIs (generate_commit_message, etc.) have default implementations
• Enables callers to control prompt construction, required for split commit's custom prompt format

CLI Parameter Restructuring

• CommitArgs and CommitOptions restructured with from_cli() constructor
• All command option structs unified in style

Dependencies

• clap upgraded to 4.5.59
• toml upgraded to 1.0
• reqwest now uses system-proxy feature for automatic system proxy support
• MSRV lowered to 1.88.0

Code Quality

• All code comments unified to English
• README fully rewritten for both EN and ZH
