Release v0.14.0

OpenAI Responses API + Hook Skip + Diff Rename Detection

Adds OpenAI Responses API support with streaming, a strip_thinking option for all providers, GCOP_SKIP_HOOK to bypass prepare-commit-msg hooks, rename-aware diff parsing, and dependency upgrades.

Added

OpenAI Responses API

• New api_style = "openai-response" sends prompts to /v1/responses instead of /v1/chat/completions; maps system prompt → instructions, user prompt → input, max_tokens → max_output_tokens
• Streaming support via process_openai_responses_stream() with typed SSE events (response.output_text.delta, response.completed, response.failed, response.incomplete)
• Full error handling: API errors, incomplete responses, parse-error counting with truncated-stream detection
• CI mode: GCOP_CI_PROVIDER = "openai-response" now accepted

strip_thinking Option

• strip_thinking = true in any provider config removes <thinking>...</thinking> and <think>...</think> blocks from generated commit messages and review JSON
• LLMProvider trait gains strip_thinking() method; all four providers (Claude, OpenAI, Ollama, Gemini) read it from extra config
• FallbackProvider respects per-provider strip_thinking for both streaming and non-streaming paths
• process_commit_response_with_options() and process_review_response_with_options() replace the old always-strip defaults; default behavior now preserves thinking tags

GCOP_SKIP_HOOK

• GCOP_SKIP_HOOK=1 environment variable skips gcop-rs hook run at three levels: shell hook script, Rust hook runner, and CLI entry point
• commit_changes() and commit_amend_changes() set GCOP_SKIP_HOOK=1 to avoid double-processing when gcop-rs itself invokes git commit

Hook Install --force Refresh

• gcop-rs hook install --force now refreshes an existing gcop-rs hook (previously only overrode non-gcop hooks)

Changed

Diff Parsing

• extract_filename_from_diff_header() returns the new path (b/) instead of the old path (a/) for renames — matching the file that must be staged
• Quoted path handling rewritten to parse the right-hand "b/..." argument for filenames containing spaces
• parse_diff_stats() and split_diff_by_file() use hunk-aware @@ tracking so --- / +++ lines inside diff hunks are counted correctly
• get_staged_diff() enables git similarity detection (DiffFindOptions) for rename and copy detection in staged diffs

Git Repository

• stage_files() passes git add -A -- before file paths to handle deletions and renames; -- separates paths from options to prevent injection
• unstage_all() in empty repos checks for staged files first, avoiding git rm --cached errors on a bare index
• get_staged_diff() force-reloads the index before diffing so external stage_files() calls are visible
• resolve_commit_trees() extracted to deduplicate commit/parent tree lookups across get_commit_diff(), get_commit_line_stats(), etc.

Stats

• Author sort stabilized with tie-breaks: primary by commit count descending, then name ascending, then email ascending
• compute_contrib_stats() counts merge commits from the author-filtered scope instead of the full commit list
• Author filtering extracted into reusable filter_commits_by_author(), author_matches_filter(), commit_matches_author_filter() functions

Dependencies

• git2 0.20 → 0.21
• rust-i18n 3.1 → 4.0
• tokio 1.50 → 1.52
• toml 1.0 → 1.1
• human-panic 2.0.6 → 2.0.8
• Removed unused dependencies: cesu8, iri-string, pin-utils

Documentation

• init step 2 now says "Use gcop-rs config to add your API key" instead of pointing to the Anthropic console
• Provider docs updated with api_style = "openai-response" examples and strip_thinking configuration
• Config examples (examples/config.toml.example, .zh) updated with new provider and option

Tests

• tests/git_commit_test.rs: hook skip, amend commit count, amend without existing commit
• tests/stats_contrib_test.rs: merge count respects author filter; DirGuard RAII pattern replaces manual set_current_dir restore
• tests/stats_test.rs: author sort tiebreaks by name and email
• src/commands/hook.rs: hook script contains skip guard, force refresh test
• src/git/repository.rs: rename detection, dash-prefixed paths, deletion staging, empty repo unstage
• src/git/diff.rs: rename new path, quoted rename, hunk-level header counting
• src/llm/provider/fallback.rs: strip thinking per-provider in generate/commit
• src/llm/provider/base/response.rs: thinking preserved by default, stripped when enabled
• src/main.rs: skip hook before config load
• src/config/tests.rs: CI mode with openai-response provider
