feat(registry): add MongoDB URI plugin

[Robbyfuu]

Adds the MongoDB URI plugin to the registry: a MongoDB driver that connects with a full connection URI (mongodb:// or mongodb+srv://), with SRV, TLS and Atlas support.

• Repo: https://github.com/Robbyfuu/tabularis-mongodb-plugin
• Release v0.2.0 with binaries for linux-x64/arm64, darwin-x64/arm64 and win-x64, each packaged with manifest.json per the publishing guide.
• 20 unit tests; CI release workflow inherited from the official mongodb plugin this is forked from.

On current Tabularis (0.15.0) it works as a standard host/port MongoDB driver. Its distinguishing feature — accepting a full connection URI verbatim — activates when the host gains URI passthrough (#495): the manifest already declares connection_uri and connection_uri_schemes, and it deliberately omits a connection_string_example so that on hosts without passthrough a pasted mongodb+srv:// URI keeps failing loudly instead of being decomposed and silently persisting a connection that cannot resolve.

Verified end to end against a live Atlas cluster together with #495 (details in that PR's thread).
