The previous commit (f963ae3) used per_item_max_bytes and per_vault_*_max_bytes
which don't match the Rust core's struct (per_item_max_count and
per_vault_*_cap_bytes). Also fixes the per-item semantics: it's a COUNT of
attachments per item, not a byte sum.
Spec and plan docs updated in-place so future Task 7 cap-enforcement
implementation uses the correct names + semantics.

Wires Rust attachment-encrypt surface into the extension. Adds GitHost
putBlob/getBlob/deleteBlob ops with Git Data API fallback for blobs
>900 KB (Contents API base64-bloats and rejects past ~1 MB). Adds the
Document item type (deferred from β₁ — needs primary_attachment).
UX: compact disclosure for attachments on every typed-item form (matches
β₂ custom-fields pattern). Image-mime rows get 16×16 thumb-icons (lazy
decrypt + object-URL lifecycle). Document detail promotes the primary
attachment to a gold "signature block" matching Totp's pattern. Item-list
gets a 📎 indicator (no count) for items with attachments.
γ₂ (later) covers trash + field-history + device + caps UI.
