doc: add blog (#201)
* doc: introduce mental models blog post

Write blog post introducing Mental Models in Hindsight 0.4.0:
- Evolution from observations and opinions
- How mental models work (consolidation, evidence tracking)
- Breaking changes and migration path
- Environment variable to enable (experimental)
- Agentic reflect explanation

* updates

* Update 2026-01-26-learning-capabilities.md

* fix: doc build issues

- Add missing code snippets for versioned docs (recall-opinions-only, recall-include-entities, bank-background)
- Fix broken links by using relative paths for version compatibility
- Update blog post title to sentence case
- Clear versions.json since v0.3 versioned docs don't exist yet
- Enable INCLUDE_CURRENT_VERSION in build script

* fix: update doc links after rebase

- Fix blog post to link to correct pages (/developer/api/mental-models and /developer/observations)
- Fix CLI docs to link to /api-reference instead of /api

* feat: add directives section to blog post

- Update intro to mention three layers of knowledge
- Add concise Directives section for compliance/guardrails
- Add directives to resources section
- Keep focus on learning capabilities (observations and mental models)

* fix: revert intro to focus on learning capabilities only

Directives are a separate feature for compliance/guardrails, not a learning capability. The blog post is about observations and mental models.
