Introduce context-menu submenus

[goanpeca]

Summary

• Declare only the populated b2.file.copy context-menu submenu and keep future submenu IDs undeclared until they have at least two concrete members.
• Move the file copy menu rows into the b2.file.copy submenu, keep bucket/folder copy as flat items, and gate file copy submenu plus inline file copy actions with b2.canListFiles.
• Derive authenticated context state through AuthService so manual auth and auto-auth share the same capability mapping.
• Add manifest tests for submenu declarations, anchor gating, inline file copy gating, and the no one-item submenu rule; update the release contract hash for contribution changes.

Follow-up notes

Pull request overview

This PR introduces initial VS Code context-menu submenu infrastructure for the B2 extension by declaring submenu IDs in the extension manifest, moving file “copy” actions under a file-only submenu anchor, and adding tests/contract updates to lock in the contribution shape.

Changes:

• Added contributes.submenus declarations for the proposed file/bucket submenu structure.
• Reworked view/item/context contributions so file copy commands live under a b2.file.copy submenu anchor (while bucket/folder copy remains flat until it has a second member).
• Added/updated manifest-focused tests and updated the release contract contributesSha256.
