Parse the age identity key once and accept every identity in it (closes #165)
Restore and verify --deep now parse the configured age secret key a
single time through a new internal helper that uses age.ParseIdentities
and hands every identity to age.Decrypt. A key file with several
identities (a whole age-keygen file) is fully accepted, so a blob
encrypted to any of its recipients decrypts, not just the first.

The helper is the first step of both commands, so a missing or
unparseable key now fails before anything is downloaded. Its error names
the configuration source (VAULTIK_AGE_SECRET_KEY or age_secret_key) and
never echoes the key value. config.extractAgeSecretKey and its silent
fallback are removed; the key is stored raw and parsed only where
decryption happens, so backup, list and prune are unaffected.

README, the restore help, and the missing-key error now show the key
read from a file with $(cat ...) rather than typed literally, keeping it
out of shell history, and say the variable may hold the whole key file.

Short: "Restore files from a snapshot",
Long: `Download and decrypt files from a backup snapshot.
This command will restore files from the specified snapshot to the
target directory.
If no paths are specified, all files are restored.
If paths are specified, only matching files/directories are restored.
The snapshot may be named by its ID or, when restoring on a host with no
local index, by the remote key that 'snapshot list' prints for a
remote-only snapshot (an unambiguous leading part is enough).
Requires the age private key in the VAULTIK_AGE_SECRET_KEY environment
variable. The variable may hold the whole age-keygen file (comments and
all of its identities are accepted); read it from the file rather than
typing the key, so it does not land in your shell history:
export VAULTIK_AGE_SECRET_KEY="$(cat vaultik_backup_private_key.txt)"
