Overview\nThis PR introduces a brand-new Snowflake plugin, adding 8 files: metadata.json, ui.json, configValidation.json, a SQL query data stream (with post-processing script), an SVG icon, README, and a setup guide. It is a self-contained plugin directory with no changes to existing files.\n\n### Security risks\nThe plugin uses OAuth 2.0 with auth code grant, which is the appropriate authentication pattern. The OAuth client secret is handled via a password field and the oauth2ClientSecretLocationDuringAuth: header setting. No hardcoded secrets or credentials are present. The SQL query data stream passes user-supplied SQL directly to Snowflake's SQL API — this is inherent to the plugin's purpose and consistent with other SQL-based plugins in the repo.\n\n### Level of scrutiny\nNew plugin PRs warrant human review regardless of bug count. The inline bug comments cover several documentation nits (typo, copy-paste errors, heading convention violations), but there is one additional concern not covered by inline comments: metadata.json sets author.type to "labs" and author.name to "SquaredUp Labs". The repo guidelines state author.type should always be "community". This may be intentional for a SquaredUp-internal plugin, but a human should confirm.\n\n### Other factors\nNo CODEOWNERS entry is added for this plugin directory, which the guidelines encourage for new plugins. The multiple documentation issues (4 nits) suggest the docs could use a polish pass before merging.
