release: bump to v1.3.1

dev is 22 commits past the v1.3.0 tag and still stamped 1.3.0, so a
release built from it would be indistinguishable from v1.3.0 on the wire,
in getnetworkinfo and to the wallet's updater.

Bump REVISION, not MINOR: the delta is bug fixes and wallet performance.
It adds no subsystem, and the new RPC-visible options (-notecachewarmup,
-checknotecache) are debug-help only.

  configure.ac, src/clientversion.h  1.3.0 -> 1.3.1 (CLIENT_VERSION 1030150)
  doc/man/*.1                        version strings restamped
  contrib/debian/changelog           1.3.1 entry
  src/chain.h                        the CLIENT_VERSION comment

The man page content needs no regeneration: every option in
`dragonxd --help` at 3032eb786 is already in dragonxd.1, and the two new
options appear only in -help-debug.

No consensus change since v1.3.0, so PROTOCOL_VERSION and
MIN_PEER_PROTO_VERSION are unchanged.

+dragonx (1.3.1) stable; urgency=high
+
+  * Fix a file-descriptor double close that could corrupt wallets and block
+    files and crash the node. wolfSSL's CloseSocket macro turned every P2P
+    disconnect into a bare close() that left the socket handle set, so the
+    same fd number was closed again after another thread had reused it,
+    often for wallet.dat, a BDB log or a block file. Present in every
+    release since the 2020 move to wolfSSL.
+  * Defense in depth: block and undo files opened for reading are now
+    read-only; a wallet error while processing a block now shuts the node
+    down cleanly instead of crashing it; the BDB logs are kept when the
+    shutdown flush fails, so the next start can recover the wallet.
+  * Fix an abort on the next block after a note arrives at an address
+    imported with z_importviewingkey.
+  * Large wallets: break the replay -> witness rebuild -> kill loop. Witness
+    extension is much cheaper and parallel, the chainstate is flushed at
+    least hourly, replayed transactions keep their nullifiers (no mass
+    reseed), and the wallet locator never runs ahead of what the wallet has
+    processed.
+  * Much faster balance and note RPCs on wallets with thousands of Sapling
+    notes, through an in-memory cache of decrypted notes (warmed at startup,
+    -notecachewarmup) and by avoiding deep copies; history RPCs gather
+    Sapling keys once per call.
+  * -txindex=0 nodes now include fully shielded notes in queries with
+    minconf >= 2, so -zsweep and -consolidation now move them.
+  * No consensus change; PROTOCOL_VERSION is unchanged.
