Deduplicate entry points and templates

CLAUDE.md and AGENTS.md (now a symlink) shrink to a pointer at the
bootstrap, which absorbs the rule-editing instructions. The two
identical per-tool templates merge into rules/ai/AGENT.template.md.
README drops the read path duplicated from the bootstrap. The
web-visual-baseline starter CSS/HTML duplicated assets/view.css and is
removed in favor of the vendored assets.

 Add as a git submodule to any project — agents (Claude, Codex) will read the rules automatically.
 
-## Agent Read Path
-
-Agents should not read the whole submodule by default.
-
-Start here:
-
-1. `bible/AGENT-BOOTSTRAP.md`
-2. `bible-local/README.md`
-3. Only the relevant files in `bible-local/architecture/`, `bible-local/decisions/`, and
-   `bible/rules/patterns/...`
-
-The bootstrap file contains:
-- the always-on core contracts
-- a router from task type to relevant contracts
-- the default rule to skip unrelated contracts
+Agents start at `AGENT-BOOTSTRAP.md` — it defines the read path, always-on contracts,
+and the task router. Nothing in this README duplicates it.

 ## Project Setup
 
 Each project needs:
 - `bible/` — this submodule
 - `bible-local/` — project-specific architecture (data model, API, ADL)
-- `CLAUDE.md` + `AGENTS.md` — point agents to the bootstrap file and to `bible-local/`
+- `CLAUDE.md` + `AGENTS.md` — copies of `rules/ai/AGENT.template.md` pointing agents to the bootstrap
 
-See `rules/ai/claude/CLAUDE.template.md` for a ready-made template.
-See `rules/ai/codex/AGENTS.template.md` for a ready-made Codex template.
 See `rules/patterns/go-project-bible/contract.md` for what goes in `bible-local/`.
