fix: use package version for MCP server version instead of hardcoded 0.1.0 (#744)

* fix: use package version for MCP server version instead of hardcoded 0.1.0

The server reported version "0.1.0" to MCP clients regardless of the
actual package version. This reads the version from package metadata
(managed by semantic-release) so the server correctly identifies itself
as e.g. "6.7.2". The MCP_SERVER_VERSION env var still works as an override.

Closes #741

* fix: use 'unknown' fallback instead of '0.0.0-dev'

Avoids confusion with the dev server addon.
