Log Message:
Replace magic numbers with named constants; refactor key_algo API

Replace bare numeric literals throughout the library with DSSH_-prefixed
macros: DSSH_VERSION_STRING_MAX, DSSH_KEXINIT_COOKIE_SIZE,
DSSH_KEXINIT_NAMELIST_COUNT, DSSH_ALGO_NAME_MAX, DSSH_DISCONNECT_DESC_MAX,
DSSH_ASCII_DEL, DSSH_MPINT_SIGN_BIT, DSSH_NAMELIST_BUF_SIZE, and
DSSH_REQ_DATA_BUF_SIZE.

Replace inline string literals in dispatch comparisons with file-scope
static const char arrays (str_signal, str_session, method_password, etc.)
using DSSH_STRLEN() to keep lengths in sync with content.

Move MAC verification buffers from hardcoded [64] stack arrays to
session-level allocations sized to the negotiated digest_size, eliminating
the arbitrary size constant.

Refactor dssh_key_algo_pubkey to return a const pointer to a cached blob
in cbdata (computed once, reused), and dssh_key_algo_sign to malloc its
output (caller frees).  This eliminates DSSH_HOST_KEY_BUF_SIZE and
DSSH_SIGNATURE_BUF_SIZE entirely  no caller-side buffer size guessing.
