Release v0.11.0

Project Config & Smart Diff - Team-Shared Configuration and Intelligent Diff Truncation

Introduces project-level configuration for team-shared conventions, commit convention definitions (Conventional/Gitmoji/Custom), and intelligent file-level diff truncation that replaces the old byte-level approach.

Added

Project-Level Configuration

• New .gcop/config.toml for team-shared, non-sensitive configuration
• Searches upward from working directory, bounded by .git root
• Merges with user-level config; project config overrides user config
• Security check warns if api_key is found in project config
• New gcop-rs init --project command to scaffold .gcop/config.toml in repo root

Commit Convention Definitions

• New [commit.convention] config section to guide LLM-generated commit messages
• Three built-in styles: conventional (type(scope): description), gitmoji (:emoji: description), custom
• Optional types list to restrict allowed commit types
• Optional template and extra_prompt for full customization
• Convention is injected into LLM prompt as guidance (no hard validation)

Smart Diff Truncation

• Replaces byte-level truncation with file-level intelligent truncation
• Auto-detects generated files (.lock, .min.js, package-lock.json, pnpm-lock.yaml, go.sum, etc.) and downgrades to summary-only
• Sorts remaining files by size, greedily packs within token budget
• All files retain at least a stats summary (+N -M lines)
• New FileDiff struct and split_diff_by_file() / smart_truncate_diff() functions

Changed

Configuration Load Priority Updated

• New 5-level priority (low to high): Defaults, User config, Project config, GCOP__* env vars, CI mode
• load_config_from_path() now accepts optional project config path

Diff Truncation Message Improved

• Old: "Diff too large, truncated to avoid exceeding LLM token limit"
• New: "Diff too large, some files shown as summary only to fit LLM token limit"

Documentation Updated

• init command docs: added --project option
• Configuration guide: added project-level config section with priority table and security notes
• Provider and installation docs: minor corrections for macOS paths and Gemini references
