Add writings directory with first two essays

[klappy]

Summary

• Introduces writings/ as a new content directory alongside canon/, odd/, and docs/
• Adds The Most Expensive Problem (essay) and The Parallel Architecture (appendix) with full frontmatter
• All internal cross-references use klappy://writings/* URIs for oddkit resolution

What is writings/?

The authors voice -- essays, appendices, articles, posts. These are not canon, not methodology, not documentation. They are indexed and managed by the knowledge base but they are writing, not system output.

Documents

File	Type	Tags
writings/the-most-expensive-problem.md	essay	writings, essay, epistemics, knowledge-transfer, ai, verification, epistemic-os
writings/the-parallel-architecture.md	appendix	writings, appendix, epistemics, theology, biblical-worldview, knowledge-transfer, ai, apocrypha

Frontmatter includes

• Discovery metadata (hook, description, slug)
• Social graph (og_*, twitter_*)
• Relationships (derives_from, related, parent)
• Type system (type: essay|appendix, public: true)

Depends on

oddkit PR: klappy/oddkit feature/include-metadata (adds writings/ to index patterns so these docs are discoverable)

Test plan

• Verify oddkit_search with tag writings returns both documents
• Verify oddkit_get with klappy://writings/the-most-expensive-problem resolves
• Verify klappy://writings/* cross-references in both documents are correct

Note

Low Risk
Content-only addition (new markdown documents) with no code or runtime behavior changes; main risk is navigation/indexing expectations if writings/ isn’t yet included in downstream tooling.

Overview
Adds a new writings/ content area with two public, cross-linked longform documents: The Most Expensive Problem (essay) and The Parallel Architecture (appendix).

Both files include rich frontmatter for discovery/social metadata and relationship links via klappy://writings/* URIs (including derives_from references into the canon), enabling them to be indexed and navigated like existing docs content.
