gmaps: fix missing dependency install + wire verify (v6 / 1.1.0)

The connector shipped no requirements.txt, so ensure_installed_host()
installed nothing and every tool call failed with "No module named
'googlemaps'" while the server still answered tools/list — skald logged
"connected — 6 tool(s)" on a connector that could not work.

- add requirements.txt (googlemaps>=4.10.0); deps were declared in the
  manifest's `dependencies` field, which skald only uses for the card
- wire the shipped verify.py through a `verify` manifest block, so a
  broken install fails visibly at enable time instead of silently
- verify.py puts .pydeps on sys.path: skald sets PYTHONPATH only for the
  server process, not for the `sh -c "python3 verify.py"` verify step
- drop the inert mcp_config.env {SECRET:…} placeholder — those tokens are
  substituted in the URL only, never in env values
- realign manifest/fragment versions (were 2/1.0.1 vs 5/1.0.4); skald
  prefers the manifest, so "update available" could never appear
- requires ENV -> API_KEY; drop deprecated secrets/ path from error text
- regenerate the index
