fix(memory-safety): add bounds checks for binary protocol parsing

Three related slice-bounds / OOM issues in binary protocol parsing code,
all reachable from untrusted network responses.  Same root class as the
telnetmini NTLM len<12->len<48 fix (1aff867).

## Finding 1 — pkg/js/libs/kerberos/sendtokdc.go: sendTCP OOM via
spoofed KDC length field (DoS)

A rogue or spoofed KDC can return a 4-byte big-endian length of 0xFFFFFFFF
(~4 GiB).  sendTCP called make([]byte, s) unconditionally before checking
the value.  Added maxKDCResponseSize = 1 MiB cap; reject before allocating.
Also upgraded conn.Read(sh) → io.ReadFull so the 4-byte header is always
completely read on a slow link.

## Finding 2 — pkg/js/libs/kerberos/sendtokdc.go: TGStoHashcat and
ASRepToHashcat panic on truncated KDC cipher (slice-bounds panic)

Cipher[:16] panics when len(Cipher) < 16.  A KDC reply with a truncated
EncryptedData block (or a crafted Unmarshal result) reaches this code path
via GetServiceTicket / EnumerateUser.  Added explicit < 16 guard returning
an error instead of panicking.

## Finding 3 — pkg/js/libs/smb/smbghost.go: detectSMBGhost OOM via
spoofed NetBIOS length field (DoS)

Same pattern as Finding 1: the 4-byte NetBIOS body-length is from the
server, structs.Unpack returns it as an int, and ConnReadNWithTimeout
calls make([]byte, length).  A spoofed server can advertise 0x7FFFFFFF
(2 GiB).  Added maxSMBGhostBodySize = 10 MiB cap.

Tests:
- TestTGStoHashcat_NoPanicOnShortCipher: cipher lengths 0-15 must error
- TestASRepToHashcat_NoPanicOnShortCipher: same for AS-REP
- TestSendTCP_OversizedResponseRejected: spoofed 1 MiB+1 response errors
- TestSendTCP_SmallValidResponseSucceeds: 32-byte response succeeds
- TestDetectSMBGhost_OversizedLengthIsRejected: spoofed 10 MiB+1 errors

All 22 new tests pass.  Existing telnetmini tests unchanged.
