feat(scripts): sign-daemon-release release command (package + sign prebuilt binaries)

Adds `sign-daemon-release.sh release <secret.key> <version>`: zips each staged
prebuilt-binaries/dragonxd-{linux,mac,win}/ into dragonx-<version>-{linux-amd64,
macos,win64}.zip, signs each (detached ed25519), and prints the SHA-256 checksum
table for the release body. Platforms with no staged daemon are skipped; warns
if the signing key doesn't match the pubkey pinned in daemon_updater.h. Keeps the
existing keygen/pubkey/sign subcommands.

# Sign dragonx full-node release archives for the wallet's in-app daemon updater (ed25519).
# Package the prebuilt dragonx full-node binaries into per-platform release archives and sign them
# for the wallet's in-app daemon updater (ed25519 over the EXACT archive bytes).
#
# The wallet verifies a detached ed25519 signature over the EXACT archive bytes against a public
# key pinned in src/util/daemon_updater.h (kDaemonSignaturePublicKeyBase64). Verification is
# MANDATORY (kDaemonRequireSignature = true): an in-app update is refused unless a valid signature
# is published. For each archive <name>.zip this produces <name>.zip.sig holding the base64 of the
# raw 64-byte ed25519 signature — upload that .sig next to the .zip as a release asset.

# (kDaemonRequireSignature = true): an in-app update is refused unless a valid "<archive>.sig" is
# published next to the archive. The wallet also checks each archive's SHA-256 against a markdown
# checksum table in the release body, so `release` prints that table for you to paste in.
#
# Uses OpenSSL (>= 1.1.1) only — no Python/PyNaCl needed. OpenSSL's ed25519 is PureEdDSA (RFC 8032),
# the same primitive libsodium's crypto_sign_verify_detached checks, so signatures are compatible
# (the same flow the wallet's unit tests verify for the miner updater).
