kb: retire pi-installation association (OMP is the primary harness)

Purge live-state claims that ~/.pi is our harness; keep general
pi documentation in omp-docs/ and dated historical records.

- README.md: single config source; Legacy Notes reworded
- AGENTS.md: drop 'like ~/.pi did' framing
- APPEND_SYSTEM.md: okf-spec -> omp-docs/references/okf-spec.md
- dotfiles/zsh/.zshrc: systemprompt alias -> APPEND_SYSTEM.md
- managed skill llm-fleet-model-swap + model_config_sync skill:
  single-source models.yml; validation script YAML-only
- memories (MEMORY.md, memory_summary.md, learned.md): single source
- omp-docs: .okf root -> ~/.omp/omp-docs; de-live pi-era claims in
  pi/index.md, pi-web-access.md, engineering/agents-files.md

 - Self-contained: inline CSS only, NO CDNs (must work from file:// offline). Dark theme CSS vars (#1a1b26 bg family works).
 - Sticky top nav, section anchors, `<pre class=code><code>` blocks, commit hashes as `.tag` chips.
 - Build via python (eval kernel): subprocess for git data, string concat for CSS (avoid f-string brace pain), f-strings for rows.
+- Literal `{}` in HTML text (e.g. `fallbackChains: {}`) inside an f-string is a SyntaxError — build that fragment by concatenation or double the braces.

Element counts are sufficient proof; a fullPage screenshot of a long report returns a multi-MB raw pixel buffer dump — only screenshot short pages.
