Keychain 3 now gives encryption/decryption subkeys an explicit warm-up path instead of routing gpge: through a signing-style GPG probe. The new path creates a tiny temporary ciphertext for the requested key and decrypts it through gpg-agent, which exercises the secret encryption subkey used by pass and other decrypt-oriented workflows. Also update gpga: to warm both signing and encryption/decryption capability, document the GPG subkey prefixes in the embedded manual, and add a Linux-only e2e test with an isolated GNUPGHOME and fake pinentry. Fixes #62. Fixes #204.
