Backend features: - Tree sharing via secure tokens with expiration (Issue #16) - Draft tree status with conditional validation (Issue #25) - Save session as custom tree with fork tracking (Issue #17) - Tree validation system for publish requirements - Session-to-tree conversion preserving custom steps Database migrations: - 024: Tree sharing (tree_shares table, visibility field) - 025: Tree status field (draft/published) - 25b: Merge migration for indexes New endpoints: - POST /api/v1/trees/{id}/share - Generate share token - GET /api/v1/shared/{token} - Public tree access - POST /api/v1/trees/{id}/can-publish - Validate tree - POST /api/v1/sessions/{id}/save-as-tree - Convert session Test coverage: - 20 tests for draft trees functionality - 14 tests for session-to-tree conversion - 15 tests for tree sharing Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

Adds status field to trees table for draft/published workflow:
|
|
- status: enum ('draft', 'published') - defaults to 'published' for existing trees
|
|
- Drafts allow incomplete/invalid structures for work-in-progress
|
|
- Published trees require validation before saving
