feat: Platform-Agnostic Core, Multi-VCS Support, and AIX/SkillShare Integration

[edithatogo]

Description

This PR introduces a significant evolution of the Conductor ecosystem, transitioning from a Gemini-specific extension to a platform-agnostic standard for context-driven development.

Key Improvements:

1. Unified Core Architecture: Extracted business logic into conductor-core, enabling consistent protocol behavior across CLI and IDE environments.
2. Multi-VCS Support: Decoupled Git-specific operations to support alternative version control systems like JJ and Piper, while enhancing Git-native workflows (branch-per-track, worktrees) for opt-in users.
3. Enhanced Platform Integration: Added native support for AIX and SkillShare, and unified the synchronization protocol for Claude, Codex, OpenCode, and VS Code.
4. UX Consistency: Standardized the setup and newTrack interaction flows to ensure a predictable experience across all adapters.
5. Context Hygiene: Introduced context auditing tools and minimal context bundle definitions to prevent token bloat.
6. Reliability & Quality:
   • Enforced Elite Quality Standards: 100% coverage for conductor-core, strict typing, and mandatory linting.
   • Resolved logic loops in track completion and verification phases.
   • Fixed Windows-specific command failures by refactoring shell pipes into Python runners.
