docs: rebuild KB in OKF v0.1 with live-verified facts

Copy of the legacy ~/.pi/agent/docs tree rebuilt as the command-center
knowledge base: concept files promoted to path identity, index listings
stripped of frontmatter, all wikilinks/relative links resolved, every
checkable claim verified against the live fleet (Dankserver = Ryzen 7
7700X + RTX 3090; Strix Halo is Dankclaw), unverifiable claims tagged.
kb-lint exits 0.

+# Skill File Structure
+
+A skill is a **directory** with a `SKILL.md` file. Everything else is freeform.
+
+## Standard Structure
+
+```
+my-skill/
+├── SKILL.md              # Required: frontmatter + instructions
+├── scripts/              # Helper scripts (bash, js, python, etc.)
+│   ├── process.sh
+│   └── analyze.js
+├── references/           # Detailed docs loaded on-demand
+│   ├── api-reference.md
+│   └── FORMS.md
+├── assets/               # Templates, configs, binary data
+│   └── template.json
+├── config.json           # Skill-specific configuration
+└── tests/                # Test scripts (optional)
+    └── test_runner.sh
+```
+
+## Real Example: zim-knowledge-base
+
+```
+zim-knowledge-base/
+├── SKILL.md              # Main skill instructions
+├── config.json           # ZIM file path configuration
+├── scripts/
+│   ├── search.sh         # Search ZIM file index
+│   ├── extract.sh        # Extract article as HTML
+│   ├── list.sh           # List article titles
+│   └── metadata.sh       # Get article metadata
+└── tests/
+    ├── mock_zimdump.sh   # Mock for testing
+    ├── test_runner.sh    # Test harness
+    └── test_zim_file.zim # Test fixture
+```
+
+## Real Example: brave-search (from badlogic/pi-skills)
+
+```
+brave-search/
+├── SKILL.md              # Setup + usage instructions
+├── search.js             # Brave Search API wrapper
+└── content.js            # Page content extraction
+```
