Subject: [PATCH] fix(postinstall): extend native module repair to cover
 wreq-js for pnpm global installs (#1634)

- Add fixWreqJsBinary() to postinstall.mjs with 3-strategy repair:
  1. Copy platform binary from root node_modules
  2. Copy entire rust/ directory (all platform binaries)
  3. npm rebuild wreq-js fallback
- Fixes macOS arm64 global pnpm installs shipping only Linux binaries
- Adds reasoning replay cache feature for DeepSeek V4 (#1628)
- Updates CHANGELOG.md with both fixes

 - **fix(docker):** Set `NPM_CONFIG_LEGACY_PEER_DEPS=true` in the Docker builder layer before `npm ci` and remove duplicate `postinstallSupport.mjs` COPY instruction — fixes container image build failures introduced in v3.7.0 (#1630 — thanks @rdself).
 - **fix(antigravity):** Hide deprecated Gemini-routed Claude 4.5 models from public catalogs and model lists. Legacy `gemini-claude-*` aliases now silently resolve to current Claude 4.6 equivalents. Replace dynamic reverse-alias generation with an explicit allowlist for predictable model visibility (#1631 — thanks @backryun).
 - **fix(types):** Add explicit type annotations to sync-env test helpers and dynamic import casts to satisfy `typecheck:noimplicit:core` CI gate.
+- **fix(reasoning):** Implement Reasoning Replay Cache — hybrid memory/SQLite persistence for `reasoning_content` in multi-turn tool-calling flows. Automatically captures reasoning from DeepSeek V4, Kimi K2, Qwen-Thinking, and GLM models and re-injects it on follow-up turns to prevent HTTP 400 errors from strict reasoning-content validation. Includes dashboard telemetry tab, REST API, and 21 unit tests (#1628 — thanks @JasonLandbridge).
+- **fix(postinstall):** Extend postinstall native module repair to cover `wreq-js` — detects missing platform-specific `.node` binaries inside `app/node_modules/wreq-js/rust/` and copies them from the root install. Fixes global `pnpm` installs on macOS arm64 where the standalone app directory only contained Linux binaries (#1634 — thanks @MarcosT96).
