docs: rewrite README for the working system + CHANGELOG; bump to 0.2.0

README was a pre-MVP stub (wrong, said set an Anthropic key). Now documents the
real system: two-layer architecture, role-based backends, memory tiers + dream
cycle, poker copilot (sessions/hands/villains/equity/recaps), web pages, ratings,
and how to run it as services. Added CHANGELOG with the 0.2.0 feature set. Legacy
v0.6.x design docs kept in docs/ as history.

+# Changelog
+
+## 0.2.0 — first working system
+
+The leap from "chat + memory baseline" to a working, persistent companion with a
+real poker copilot. Highlights:
+
+### Self & inner life
+- **Autonomy Core** — evolving self-state (mood, valence/energy/confidence/curiosity,
+  self-narrative, relationship), injected into every turn.
+- **Dream cycle** — unattended loop driven by four drives (continuity, coherence,
+  curiosity, stability); consolidates memory and reflects on its own. Runs as a
+  systemd service on the MI50 (free/local).
+- **Two-step metacognitive reflection** — draft → examine own draft for flattery /
+  sycophantic drift / repetition → revise; what she catches is stored as metacognition.
+- **Time awareness** — perceives the current moment, time since Brian last spoke, and
+  time since her own last reflection.
+- **Permanent journal** — every reflection + a deliberate "knowing" journal note kept
+  forever (the capped lists are just a working window).
+- **Accurate self-model** — knows her own architecture (memory tiers, dream cycle);
+  won't recite stale specs or confabulate how she works.
+- **Anti-repetition** — idle reflections draw varied grist (resurfaced memories /
+  "wander" prompts) and are permitted non-Brian interiority.
+
+### Memory & consolidation
+- Tiered memory: exchanges → session gists → profile → monthly eras → narrative.
+- Map-reduce consolidation; gists dated by the real conversation, not the run.
+
+### Poker copilot
+- Structured **session / hand / villain** tracking + stats ($/hr by stake/venue/game).
+- **Hand-history reconstruction** from rough shorthand → replayable table viewer with
+  live stacks, progressive board, step-through; `x` for unknown cards (never invented).
+- **Auto-accumulating villain dossiers** + player lookup; stats emerge with sample size.
+- **Deterministic equity tool** (`analyze_spot`, treys) — exact equity / made hands /
+  outs; mandated over LLM eyeballing.
+- **Session recap** generation (`.md`, Brian's format) + export; `/hands` browser.
+- **Backfill** of historical sessions/villains from curated `.md` logs.
+
+### Tools & web
+- **Tool-calling** in chat (cloud): poker tools, `journal_write`, `note`.
+- Web UI: Markdown chat, **cloud model selector**, live **/logs**, **/self** (read her
+  mind), **/journal**, **/hands** + **/hand/{id}** replayer, **/recap/{id}**.
+- **👍/👎 rating system** — feedback on replies and thoughts stored as
+  `(context, content, rating)`; `/ratings/export` (JSONL) seeds future fine-tuning.
+- RTO black-and-orange theme across all pages.
+
+### Ops
+- Role-based backends (cloud / MI50 / local Ollama); MI50 OpenAI-compatible backend.
+- systemd user services for `lyra-web` and `lyra-dream`, with bounded stop timeouts.
+- SQLite WAL + busy-timeout so the dream process and web server coexist.
+
+## 0.1.0 — scaffold
+- uv project, SQLite memory with cosine recall, LLM router (local/cloud), persona +
+  chat loop, web UI baseline, ChatGPT history import.
