google-trends: fix broken MCP handshake and RSS articles (v2 / 1.1.0)

The server never implemented `initialize`, so every MCP client got
-32601 to its opening request and aborted before listing a tool. Also
missing: `notifications/initialized` and `ping`; `tools/list` returned a
bare array instead of {"tools": [...]}; notifications (no `id`) got a
full response written to stdout.

Rewritten to the shape the other local connectors already use (TOOLS
manifest + TOOL_DISPATCH, `_text_result` with isError, handle_request
returning None for notifications).

Also fixed:
- include_articles always returned nothing: trendspyg emits
  `news_articles`, the mapper read `articles`. explore_link kept too.
- fn(**arguments) turned a bad argument into -32603; handlers now take
  an args dict and coerce/clamp.
- errors were returned as successful results; now isError: true, with
  trendspyg's typed exceptions translated into actionable messages.
- browser calls could run ~100s (10 retries x 8s); capped at ~25s.
- verify.py shipped but connector.json declared no `verify` block; wired
  it and upgraded the script to a real RSS fetch.
- explore mutated trendspyg's ExploreEnvelope; dropped the no-op
  output_format param; trendspyg pinned >=1.6.0 and imported defensively.
