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.

+# How the Pi Agent Loads and Uses Skills
+
+## Discovery Flow
+
+1. Pi scans all configured skill locations at startup
+2. Extracts names and descriptions from each `SKILL.md`
+3. Builds the system prompt with skill descriptions in XML format
+4. The LLM decides which skill(s) to activate based on the user's prompt
+5. When activated, the agent reads the full SKILL.md using the `read` tool
+
+## Progressive Disclosure Pattern
+
+```
+System prompt (always in context):
+  - "Available skills: brave-search (Web search...), browser-tools (Browser automation...), ..."
+
+User: "Search for information about React hooks"
+
+Agent decides: activate brave-search
+Agent reads: ~/.pi/agent/skills/brave-search/SKILL.md (full file)
+Agent executes: {baseDir}/search.js "React hooks"
+```
+
+## This is progressive disclosure: only descriptions are always in context, full instructions load on-demand.
