docs(readme): rewrite intro — multi-LLM + sub-agents + sleep + token streaming

Old intro talked about 'MCP bridges generate context for Cursor/Continue/...'
which was outdated and missed everything shipped in v0.40–v0.45:
- 5 LLM CLIs unified (Claude / Grok / Gemini / Copilot / Kimi)
- Sub-agents on any backend via spawn_agent MCP tool
- 3-tier policy enforcement (TIER 1/2/3)
- Three-phase sleep (A/B/C)
- Native token streaming pass-through

Also removed [REAL: shell-cmd] hygiene markers from user-facing text
(those belong in author tooling, not the README).

Author & collaboration section emptied to a TODO comment so the user
can write their own annotation (per their explicit request).

 # KeiSeiKit
 
-A **multi-LLM substrate** that gives any agentic coding tool persistent
-memory, deterministic agent identity, and self-maintaining orchestration.
-Works first-class with Claude Code; MCP-compatible bridges generate
-context for Cursor / Continue / Zed / Aider / Windsurf / Cline /
-OpenClaw / Kimi from the same source-of-truth.
+A **multi-LLM substrate** for agentic coding. Same agent definition,
+any LLM backend — Claude Code, Grok, Antigravity (Gemini), GitHub
+Copilot, or Kimi. Pick your orchestrator with `kei pick`; agents
+spawn sub-agents on other LLMs via MCP `spawn_agent`; safety hooks
+enforce on every backend through a 3-tier model. Three-phase nightly
+sleep consolidates 30-session windows into morning markdown reports.

+
+## Highlights
+
+- **5 LLM CLIs unified.** Claude Code (native hooks), Grok (port to
+  `~/.grok/settings.json`), Antigravity/Gemini, GitHub Copilot, Kimi.
+  DNA-routed: each agent's manifest declares a `provider`;
+  `kei agent <name>` resolves DNA → primary → claude fallback.
+- **Sub-agents on any backend.** Agents call `spawn_agent` (built-in MCP
+  tool in `kei-mcp`) to dispatch other agents to whichever LLM fits
+  the task. Cross-CLI orchestration without lock-in — Grok can spawn
+  critic@Claude, then ml-implementer@Gemini, all from one session.
+- **3-tier policy enforcement.** Claude + Grok TIER 1 (full native
+  PreToolUse), Copilot TIER 2 (MCP-wrapped + `--excluded-tools=shell`),
+  Agy + Kimi TIER 3 (advisory). `no-github-push`, `safety-guard`,
+  `destructive-guard`, `citation-verify`, `numeric-claims-guard`
+  surface on every backend that supports tool-call gating.
+- **Three-phase nightly sleep.** Phase A (incubation — queued tasks
+  via `/sleep-on-it`), Phase B (REM consolidation — analyzes last 30
+  sessions, writes morning markdown), Phase C (NREM deep-sleep, every
+  7 days — conflict scan + refactor proposals). Outputs are markdown;
+  you decide what merges.
+- **Native token streaming.** Each backend streams in its own print
+  mode (`claude -p`, `grok --print`, `agy --print`, `copilot --prompt`);
+  KeiSeiKit composes the agent prompt + task and passes through. No
+  buffering layer.
+- **Persistent memory.** SQLite ledger + content-addressable store,
+  session-spanning context, cross-machine sync via memory-repo.
+- **Agent DNA.** Deterministic variable-length identity per
+  invocation: `<role>::<caps>::<scope-sha8>::<body-sha8>-<nonce8>`.
+  Same task → same prefix → "did this run before?" via SQL, no
+  embeddings.
+- **Constructor Pattern.** Substrate, not framework. You compose; it
+  doesn't dictate workflow. File >200 LOC → decompose. No mixins, no
+  DI containers, no abstract factories.
+- **Self-maintaining.** Every substrate edit cascades: registry
+  updates, agent regeneration, DNA index refresh, keimd graph
+  reindex. Auto-self-indexing via kei-registry SQLite.
