On Windows, recover the Adobe ADEPT user key from an installed/activated Adobe Digital Editions and use it automatically, so ADEPT EPUBs decrypt with no --key argument. Ported from adobekey.py: * Build the DPAPI entropy byte-for-byte: system-volume serial number, CPUID leaf-0 vendor (EBX|EDX|ECX) and leaf-1 signature, and the ADE username, packed as ">I12s3s13s". * CryptUnprotectData (DPAPI) recovers the key-encryption-key from the HKCU\Software\Adobe\Adept\Device "key" value, then each per-credential privateLicenseKey under ...\Activation is AES-128-CBC decrypted and the DER RSA key taken from byte 26 onward. Decryption now lazily auto-extracts and retries when no supplied key fits, and newly found keys are written back to the TOML config so later runs are offline. Uses the `windows` (DPAPI/volume info) and `winreg` crates behind cfg(windows); pure-Rust crypto unchanged. Verified end-to-end on a real ADEPT EPUB: the key was extracted from the local ADE and the book decrypted to a valid, DRM-free EPUB (rights.xml and encryption.xml removed, content readable).
