Functions
void	bento_devmode_init (void)
	Idempotent; seeds the 32-byte RAM secret. Every public devmode entry self-calls it.
void	bento_devmode_nonce_issue (uint8_t nonce_out[BENTO_DEVMODE_NONCE_LEN])
	Fill a fresh 16-byte nonce, overwriting any pending one; starts the TTL clock.
bool	bento_devmode_unlock (const char *hmac_hex, size_t hmac_hex_len)
	Verify the HMAC against the pending nonce; consumes the nonce on any call (one-shot).
void	bento_devmode_lock (void)
	Clear the unlocked flag.
bool	bento_devmode_is_unlocked (void)
	Whether privileged verbs (bento.exec) are permitted right now.
size_t	bento_devmode_secret_hex (char *out, size_t out_sz)
	The secret as 64 hex chars + NUL, or 0 if the buffer is too small; never log it to UART.
void	bento_devmode_emit_provision (void)
	Emit the provision event once per boot on the CONNECTED transition; a failed send retries.
size_t	bento_devmode_secret_fp_hex (char *out, size_t out_sz)
	First 4 bytes of SHA-256(secret) as 8 hex chars + NUL — safe to log.
