Add model information to commit message attribution

[itdove]

Description

Currently, all commits include generic attribution regardless of which Claude model was used:

Co-Authored-By: Claude <noreply@anthropic.com>

Since DevAIFlow now supports multiple Claude models (Opus 4.6, Sonnet 4.5, Haiku 4.5) via model profiles (vertex, ollama-local, etc.), the attribution should reflect which specific model contributed to the code.

Current Behavior

All commits use the same generic attribution:

🤖 Generated with [Claude Code](https://claude.com/claude-code)

Co-Authored-By: Claude <noreply@anthropic.com>

Proposed Behavior

Commits should include the specific model that was used:

🤖 Generated with [Claude Code](https://claude.com/claude-code)

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Or for other models:

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>

Benefits

• Transparency: Clear attribution of which AI model contributed
• Accuracy: Especially important when different models (Opus vs Sonnet vs Haiku) have different capabilities
• Analytics: Teams can track which models were used for different types of work
• Historical context: Future developers can understand what AI assistance was available at the time

Implementation Considerations

1. Model Profile Mapping: The Session.model_profile field stores profile names (e.g., "vertex", "ollama-local"), not model names. Need to:

   • Map profile → actual model name (e.g., "vertex" → "Claude Opus 4.6")
   • Handle custom profiles or unknown profiles gracefully

2. Fallback Handling: When model info is unavailable:

   • Keep existing generic "Claude" attribution
   • Don't break commits if model detection fails

3. Location: Modify _generate_commit_message() in devflow/cli/commands/complete_command.py to:

   • Access session's model_profile
   • Resolve to actual model name
   • Include in Co-Authored-By line

4. Format Options:

   • Option A: Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
   • Option B: Co-Authored-By: Claude (Sonnet 4.5) <noreply@anthropic.com>
   • Option C: Keep generic "Claude" but add comment with model

• Session model tracking: Session.model_profile field in devflow/config/models.py:779
• Model provider config: ModelProviderConfig in config models

• Model name included in Co-Authored-By line for commits
• Falls back to generic 'Claude' when model info unavailable
• Handles all supported model profiles (vertex, ollama-local, etc.)
• Existing tests still pass
• New tests validate model attribution

Issue #191: Add model information to commit message attribution

Changes made:

1. devflow/utils/model_provider.py — Added 3 new functions:

   • parse_claude_model_display_name() — Parses model IDs like claude-opus-4-6 → "Claude Opus 4.6", handles older claude-3-5-sonnet format, date suffixes, context markers, and non-Claude models
   • get_model_attribution_name() — Resolves display name from config profile, falls back to "Claude"
   • get_co_authored_by_line() — Returns full Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> string

2. devflow/cli/commands/complete_command.py — Replaced 5 hardcoded Co-Authored-By: Claude <noreply@anthropic.com> strings with dynamic get_co_authored_by_line(config, session.model_profile) calls (3 commit messages, 1 WIP export commit, 1 PR description)

3. devflow/cli/commands/export_command.py — Threaded co_authored_by through _sync_all_branches_for_export() → _sync_single_conversation_branch(), replaced 1 hardcoded string

4. tests/test_model_attribution.py — 28 new tests covering parsing, attribution name resolution, Co-Authored-By line generation, and commit message integration

Test results: 3737 passed, 28 new tests pass, 1 pre-existing flaky failure (unrelated test_workspace.py UUID mismatch).
