chore(release): v3.19.0 — TUI large-prompt reliability (#130) + proxy-purity context (#4) (#134)

Release prep only: bump package.json 3.18.0 → 3.19.0, CHANGELOG entry, README TUI
"what changes / what doesn't" note that the host CLAUDE.md/auto-memory is never injected.

Bundles two already-merged, independently-reviewed TUI fixes:
- #130 (PR #131): reliable large multi-line paste + version-robust turn detection.
- #4   (PR #132): never inject host CLAUDE.md / auto-memory into proxied turns.

Both verified live on PI231 + Oracle; adversarial multi-host battery passed
(0 hangs / 0 crashes / 0 injection / 0 leaks). Follow-up: #133.

No server.mjs change in this PR (package.json + CHANGELOG + README only) → cli.js
citation N/A. release_kit (Iron Rule 5.5): version_source=package.json, changelog,
README docs all updated; no new env var / endpoint / subcommand.

 # Changelog
 
+## v3.19.0 — 2026-06-02
+
+TUI-mode reliability + proxy-purity release. Two fixes diagnosed and verified live on both test hosts (PI231 / Oracle, claude 2.1.104 / 2.1.114), each its own PR with a fresh-context reviewer (Iron Rule 10), then an adversarial multi-host test battery (0 hangs / 0 crashes / 0 injection / 0 leaks). The default path (`CLAUDE_TUI_MODE` unset) is byte-for-byte unchanged.

+- **#130** — Fixed the "stuck typing" hang on large multi-line prompts. Three root causes: (1) terminal-turn detection only recognized `{system, turn_duration}`, which older claude builds (e.g. 2.1.114) don't emit → the reader ran to the wallclock and returned partial text; now also accepts an `assistant` line with a final `stop_reason` (`end_turn`/`stop_sequence`/`max_tokens`), while `tool_use` stays non-terminal. (2) Large prompts pasted via `send-keys -l` delivered embedded newlines as separate Enter events → the prompt never landed; now uses `tmux load-buffer` + `paste-buffer -p` (bracketed paste, atomic). (3) The paste-landed check false-positived on claude's empty curly-quote placeholder → Enter fired into an empty box; now positive-signal-only (`[Pasted text]` / prompt text) with a readiness/paste-verify poll + fast-fail (deterministic ~5s error instead of a 120s wallclock hang).
+- **#4** — TUI-mode never injects the host's `CLAUDE.md` / auto-memory into proxied turns. OCP is a proxy: the proxied client (OpenClaw / an IDE) owns its own context and memory. `buildTuiCmd` now always sets `CLAUDE_CODE_DISABLE_CLAUDE_MDS` + `CLAUDE_CODE_DISABLE_AUTO_MEMORY` (unconditional — proxy purity is not an opt-in). Verified live with a marker `CLAUDE.md`: obeyed by the proxied turn before the fix, blocked after, on both hosts. Residual host-context vectors (managed-policy / `settings.json` / output-styles) tracked in #133. The env is delivered via an `env`-prefix on the tmux pane command (tmux does not forward the spawning process's environment, and `new-session -e` requires tmux ≥3.2 while the cloud host runs 2.7).

 ## v3.18.0 — 2026-06-01
 
 Hardening release from a multi-agent code audit (1 P0 + 14 P2 + 2 P3 findings, each adversarially verified and independently reviewed) plus three follow-ups (#123–#125). Every change shipped as its own PR with a fresh-context reviewer (Iron Rule 10). The single-user default path (`AUTH_MODE=none`, no TUI) is behavior-identical **except** the `/health` change in #109.

 - **Callers see no API change.** The response is a normal OpenAI completion object or chunked SSE — identical wire format.
 - **No real token streaming.** TUI-mode buffers the full response then replays it as chunked SSE. You will see a delay then the complete response rather than real-time tokens.
 - **Cache and singleflight work normally.** TUI-mode writes the buffered response to the cache on success; cache-hits skip the interactive turn entirely.
+- **The host's `CLAUDE.md` / auto-memory is never injected.** OCP is a proxy — the proxied client (OpenClaw / your IDE) owns its own context and memory. TUI-mode always runs `claude` with `CLAUDE_CODE_DISABLE_CLAUDE_MDS` + `CLAUDE_CODE_DISABLE_AUTO_MEMORY`, so a `CLAUDE.md` on the OCP host can never leak into proxied turns (verified live; see #4). Built-in tool schemas + the interactive system prompt remain (the inherent ~20–35K context floor of interactive mode); MCP is hard-disabled.
 - **Default path unchanged.** Unset `CLAUDE_TUI_MODE` and restart → `callClaude` / `callClaudeStreaming` are used again, byte-for-byte identical to today.
