v0.11.0

Changed

• Shell-safe identity keys. Spaces in an account or role name now collapse to hyphens, so an account named "Acme Corp Account" shows and resolves as Acme-Corp-Account/AWSReadOnlyAccess with no quoting needed. Lookups still accept the raw spaced name, so pasting a name from the AWS console keeps working.
• Auto-login. A command that needs a session but finds none now logs you in automatically instead of stopping with "Run 'grantry login' first" (ls, run, switch, console, populate, graph, init, admin, credential-process). Non-interactive contexts (no terminal) still report the missing session on stderr rather than opening a browser.

Fixed

• Access graph "Export SVG" no longer produces an all-black image. The exported file carries its own colors and an opaque background, rendering the same as the on-screen graph in any viewer.
