fix: restore v2.0 doc paths and update blog posts for v2

After reverting docs default back to 1.x (commit 4754215), restore correct
v2.0 paths in cross-references:
- docs/migration.md: /docs/configuration → /docs/2.0/configuration
- docs/sdks/python.md: /docs/configuration → /docs/2.0/configuration

Update blog posts with v2 changes:
- blog/2022-11-19-waterline-ui.md: Add v2 banner, update package name
  laravel-workflow/waterline → durable-workflow/waterline
- blog/2026-02-07-building-a-durable-ai-travel-agent-with-laravel.md:
  Update method names execute() → handle() for v2 API

Fixes #275
