Add Google Photos preset with binary-safe uploads

[zrm625]

Summary

Google Photos uploads need a raw byte upload step before mediaItems.batchCreate, but Google Discovery does not publish that /uploads endpoint as an operation. Executor also receives tool arguments as JSON, so binary media cannot be safely sent through a plain body string.

This adds a focused Google Photos preset and a binary-safe bodyBase64 path for raw upload requests.

Changes

• Add a Google Photos preset for Photos Library + Photos Picker.
• Synthesize photoslibrary.mediaItems.upload for the raw /uploads token step missing from Google Discovery.
• Add bodyBase64 support for application/octet-stream OpenAPI request bodies.
• Keep the Photos preset scoped to upload, app-created media reads, and picker-selected media reads.

Dogfood

Running at https://executor.home.zakstak.com/. Verified on June 25, 2026: hosted catalog exposes google_photos, photoslibrary.mediaItems.upload exposes bodyBase64, and a tiny PNG upload-token smoke returned ok: true without calling mediaItems.batchCreate.

Hermes dogfooded this as an MCP call and uploaded more than 4,000 photos and videos through this flow.

Greptile Summary

This PR adds a focused Google Photos integration path with binary-safe uploads. The main changes are:

• A Google Photos preset for Photos Library and Photos Picker.
• A synthesized photoslibrary.mediaItems.upload operation for raw upload tokens.
• bodyBase64 support for octet-stream request bodies.
• Scoped Photos bundle conversion for mixed and partial Google API bundles.
• Tests for Photos preset discovery, scoped bundle tools, and binary upload validation.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• The latest fixes cover the binary upload validation paths.
• The Photos bundle scoping behavior is covered for mixed and partial bundles.

Important Files Changed

Filename	Overview
packages/plugins/openapi/src/sdk/invoke.ts	Adds validation and dispatch logic for bodyBase64, including invalid base64 rejection, content-type checks, required body checks, and byte-only octet-stream handling.
packages/plugins/openapi/src/sdk/extract.ts	Updates generated tool input schemas so octet-stream bodies expose bodyBase64 and required mixed-content bodies accept either JSON-style body input or base64 bytes.
packages/plugins/google/src/sdk/plugin.ts	Derives Photos consent scopes from the Photos preset URLs present in a bundle, including mixed and partial Photos bundles.
packages/plugins/google/src/sdk/discovery.ts	Adds the synthesized Google Photos upload operation and filters Photos methods and scopes during focused bundle conversion.
packages/plugins/google/src/sdk/presets.ts	Defines the Google Photos preset, preset IDs, icon, Discovery URLs, and focused OAuth scope mappings.

Nested Base64 Still Falls Through

This last bit was the part I was least sure of what you wanted. I will work on this function again tomorrow.
