docs(readme): full-pass audit — purge pre-v1.5 worldview from both READMEs

Two factual errors and a batch of stale-world copy found by auditing the
full README against v1.5.0 reality:

- "what install does" claimed twitter-cli/rdt-cli are installed by default
  — they never are (opt-in via --channels); now describes the real flow
  incl. the channel menu step
- zero-config examples listed "read a tweet" — Twitter is tier 1, not
  zero-config; list now shows truly free channels (incl. bili search)
- FAQ rewrites: xiaohongshu (OpenCLI-first, mcp for servers, xhs-cli as
  legacy fallback), Reddit (login mandatory, OpenCLI first, pinned rdt
  source), free-cost answer (tool list updated, proxy rescoped to
  restricted networks)
- platform table stops advertising write ops (发推/Post·Comment·Like) —
  aligned with the skill's fetch-only boundary
- bilibili pain-point line updated to the 412 reality
- credits gain OpenCLI and xiaohongshu-mcp
- README_en: same FAQ/table/doctor-sample fixes

 <summary><strong>How to read XiaoHongShu / 小红书 content programmatically?</strong></summary>
 
-Install `pipx install xiaohongshu-cli`, then `xhs login` (auto-extracts cookies from browser). Your agent can then use `xhs search "query"` to search notes, `xhs read NOTE_ID` to read details, `xhs comments NOTE_ID` to view comments. No Docker needed.
+On desktop, prefer **OpenCLI** (`agent-reach install --channels opencli`) — it reuses your browser's logged-in session, so if you've browsed XiaoHongShu you're set; one Chrome Web Store click installs the extension. Then `opencli xiaohongshu search "query"` / `opencli xiaohongshu note URL`. On servers use [xiaohongshu-mcp](https://github.com/xpzouying/xiaohongshu-mcp) (bundled headless browser, QR login). Existing xhs-cli installs keep working as a fallback backend (upstream unmaintained since 2026-03, not recommended for new setups).
