* Bump to 1.2.11
One change, and it is the reason a node on Windows kept collecting peers it
could not hear.
FD_SETSIZE was never defined in this tree, so it defaulted to 64 and select()
could watch the listen socket plus 63 peers -- everything past that stayed
connected and was never read again. Windows FD_SET stops adding once its array
is full and says nothing, so there was no error to notice. Because new
connections go on the end of vNodes, it was always the newest connection that
starved, including the ones dialed to fix connectivity.
Measured on two nodes: 277 and 90 CNode objects against 93 and 90 live
sockets, 316 and 355 sockets in a bound-but-never-connected state, and a status
bar reporting hundreds of peers for a node really talking to thirty.
1.2.11 raises FD_SETSIZE to 1024 on Windows, caps connections at 125, drops a
node stuck undeliverable after 60 seconds instead of holding it forever, stops
answering a failed select() with POSIX code that has no meaning on Windows, and
warns when there are more peers than select can watch.
* diag: let the node say what is wrong with it
Every hard problem in this project so far was found from outside the node --
sockets read over WMI, committed memory compared against a README, a grep over
somebody debug.log. In each case the node knew and had no way to say so.
One report, rendered identically for the GUI panel and the log: peers held vs
peers actually watched by select(), blocks received and how many arrived without
a parent, proof-of-work mode with the live miner thread count, and per peer the
age of the last message in each direction plus anything stuck unsent.

1.2.9 shipped before the last seven merges landed, and one of them is holding
two live nodes hostage.
Measured on a 32-core node running 1.2.9 today: 65,134 MB committed, which is
30 RandomX datasets at 2,142 MB each -- one per miner thread, for a node that
advertises 2 GB. A 4-core node on the same build sits at 6,568 MB, three
datasets. #68 allocates the dataset once and closes the window where a thread
could mine against one that was not finished being filled.
The rest of the release:
- #67 orphans no longer stack above earned blocks in the GUI list
- #69 no submitting a solution for a parent that is no longer the tip
- #70 a ceiling on orphan blocks, and getblocks stops repeating itself
- #71 Berkeley DB cursors get closed instead of left to the handle
- #73 bounds on what a peer can make the node allocate
- #74 the recipient no longer collects the fee when a transaction retries

relay.nostr.band went down and stayed down. Every node running 1.2.8 or
earlier spends ten seconds of every discovery pass waiting for it and
writes an error line each time -- the seed logged 2029 of them. #64
replaces it with a relay that answers and backs off from any relay that
stops answering, so the next one to go down costs nothing.

Six changes since 1.2.7, and the reason not to sit on this is #58:
coinbase transactions were not unique, two of them overwrote older ones
on the main chain, and 100 BTF stopped being reachable. Nothing in how
they were built had changed since, so it could happen again at any time.
The height now goes into the coinbase on both paths that build one
(#59, #60), which makes a repeat impossible without any coordination.
Also in: a node now notices a peer it can no longer hear and stays
audible to peers that check the same way (#55); it announces its height
in the handshake and says out loud when it falls behind the network
(#56); script evaluation has ceilings on operation count and stack depth
(#57); the tail of the chain is verified at startup and a bad tip is
backed out of instead of being mined on (#61); and the wallet now
believes the chain about what it has already spent, which is what a
restored backup gets wrong (#62).

Rendezvous no longer waits forever for a dial (#51), keys can be
exported and imported as text (#49), and mining uses every core
instead of one (#52).
#51 is the reason not to sit on this: without it a node goes
silently deaf after a while and only a restart brings it back.

Wallet backup and clean shutdown (#46).
Two reasons not to sit on this: every Linux node aborts on the
way out instead of releasing wallet.dat, and until a node has
shut down cleanly once, the wallet it wrote cannot be moved
anywhere else.

Headless mining fix (#42), ARM64 build (#41), format-string
checking (#44), gitignore for key material (#43).
#42 is the reason this release exists: -gen has mined nothing on
headless nodes since v1.2.0.

Seeds (#36), headless node (#37), README (#35), wallet crash fix (#38).

The GUI build requires libGL at load time even when started with -nogui. The
dynamic loader resolves every dependency before main() runs, so the flag arrives
far too late -- on a clean server the binary dies with
error while loading shared libraries: libGL.so.1: cannot open shared object file
and nothing suggests it would otherwise have worked. A server is where a node
most naturally lives, so this is the deployment that mattered most and the one
that failed. The AppImage additionally needs FUSE, which minimal servers lack.
Bundling libGL into the AppImage would be the wrong fix: GL has to come from the
host's driver stack, and shipping our own breaks machines that have a real GPU.
So: a second binary, built from the same node objects without ImGui, GLFW or
OpenGL. `make linux-node` produces bitflash-node-<version>-x86_64, 2.5 MB
stripped, with no graphics or FUSE dependency at all. `make linux` now builds it
alongside the AppImage. Anyone wanting a window keeps using the AppImage.
Two small moves were needed. MainFrameRepaint is called from main.cpp and
net.cpp but defined in gui.cpp, so headless.cpp provides an empty one rather
than putting ifdefs at six call sites. DateTimeStr also lived in gui.cpp while
main.cpp logs block times with it -- nothing about formatting a date is GUI
work, so it moved to util.cpp and both builds share one definition.
Verified on Debian 13:
ldd bitflash-node | grep -iE 'libGL|glfw|X11' -> nothing
ldd bitflash | grep -iE 'libGL|glfw' -> libglfw.so.3, libGL.so.1, libGLdispatch.so.0
and at runtime, from an empty datadir:
btfseed: reached ygffz37...btf via 90.156.222.107:8434
rendezvous: registered at 90.156.222.107:8434, waiting for a dial
self-resolve OK (meeting_node=90.156.222.107:8434)
btfpeers: kept 15 of 15 descriptor(s)
first block at ~30s, 3182 blocks accepted, synced to the tip
The GUI builds on Linux and Windows were rebuilt and are unaffected.

Everything since 1.2.2 is about nodes being able to find and reach each other,
which is the problem this project actually had:
#30 rendezvous registration and waiting split apart. Registering used to
block until somebody dialled, so a node could not advertise a meeting
node until it had already been reached at one. This is the root cause
of the flaky connectivity, not dead relays or stale descriptors.
#26 a node no longer advertises a rendezvous it is not registered at
#25 .btf peers that answered are remembered and dialled first (36.3s -> 2.1s)
#32 peers exchange signed descriptors, so discovery survives a relay outage
#29 debug.log stopped dropping lines under concurrency
#28 /port, so two nodes can share a machine

The AppImage step converts src/rc/bitcoin.ico with PIL, but python3-pil
was never in deps-apt, so 'make linux' failed at packaging on a clean
Debian install -- the AppImage the README points Linux users at could
not actually be produced by following the documented steps.
Version bump only renames the produced artefacts; no rebuild needed.
