build: Fix guix build for Windows, macOS cross-compile, and Namecoin branding

[mstrofnone]

Guix Build Fixes for Namecoin Core 30.x

This PR fixes several build issues encountered during reproducible (guix) builds of Namecoin Core, plus replaces remaining Bitcoin branding in user-visible macOS UI strings.

Commits

1. fix: rename bitcoin-gui to namecoin-gui in import_plugins — Qt plugin import referenced bitcoin-gui target which doesn't exist in Namecoin.

2. depends: add boost xpressive for Namecoin name RPCs — Namecoin name RPCs require boost::xpressive which wasn't included in the depends boost build.

3. fix: remove HAS_MANPAGE from bitcoin multiprocess wrapper — The bitcoin wrapper binary's install_binary_component(bitcoin) had no man page at doc/man/bitcoin.1, causing cmake --install to fail on Darwin with:

   CMake Error: file INSTALL cannot find ".../doc/man/bitcoin.1": No such file or directory.
   

4. Fix CMake target names for Namecoin (deploy, check-symbols, NSIS, macOS bundle) — Namecoin renames most executables (bitcoind → namecoind, bitcoin-qt → namecoin-qt, etc.) but Maintenance.cmake and GenerateSetupNsi.cmake still referenced the Bitcoin target names. This caused:

   • Windows: make: *** No rule to make target 'deploy'. Stop. — the add_windows_deploy_target() function's if(MINGW AND TARGET bitcoind AND TARGET bitcoin-qt ...) condition silently failed because those targets don't exist, so no deploy target was ever created.
   • macOS: Same issue — add_macos_deploy_target() checked for TARGET bitcoin-qt which doesn't exist.
   • check-symbols/check-security: Only checked the bitcoin wrapper binary, missing all the renamed executables.

5. Replace Bitcoin with Namecoin in macOS UI and user-visible strings — Fixes remaining "Bitcoin" references that users would see:

   • macnotificationhandler.mm: bundle identifier org.bitcoinfoundation.Bitcoin-Qt → org.namecoin.Namecoin-Qt
   • Info.plist.in: icon reference bitcoin.icns → namecoin.icns
   • Maintenance.cmake: macOS app bundle name Bitcoin-Qt.app → Namecoin-Qt.app, icon copy path
   • UI form strings in debugwindow.ui, optionsdialog.ui, receivecoinsdialog.ui: "Bitcoin node/network/client" → "Namecoin"

6. Fix macOS cross-compile: add CMAKE_INSTALL_NAME_TOOL for darwin targets — When cross-compiling for Darwin in the guix container, CMake's CMakeFindBinUtils module looks for install_name_tool in PATH. The guix environment only provides llvm-install-name-tool, causing:

   CMake Error: Could not find install_name_tool, please check your installation.
   

   This failed during the boost depends configure for x86_64-apple-darwin. Fixed by:

   • Adding darwin_INSTALL_NAME_TOOL to depends/hosts/darwin.mk pointing to llvm-install-name-tool
   • Registering INSTALL_NAME_TOOL in the tool chain in depends/hosts/default.mk
   • Passing -DCMAKE_INSTALL_NAME_TOOL in depends/funcs.mk for darwin cross-compile cmake invocations
   • Setting CMAKE_INSTALL_NAME_TOOL in depends/toolchain.cmake.in for the main build

Additional Notes

• OOM during Windows build: With JOBS=$(nproc) (16 jobs) and 8GB RAM, the Windows (mingw32) build was OOM-killed during heavy Qt/template compilation. Reducing to JOBS=4 resolved this.
• PSBT strings: "Partially Signed Bitcoin Transaction (PSBT)" was intentionally left as-is since PSBT is a protocol-standard term (BIP 174).
• Internal C++ class names (BitcoinGUI, BitcoinUnits, etc.) were left unchanged as they have no user-visible impact.

Note: Linux builds were from an earlier commit before the Windows/macOS fixes. The hashes above correspond to different commit SHAs because fixes were applied incrementally. A clean full rebuild from the final commit would produce a single consistent set of hashes across all platforms.

Thanks! Please rebase and submit this for the master branch (we can backport to 30.x as well if you want, but should do that later).

What is the llvm-name-tool change? Why is that required specifically for Namecoin?

Namecoin needs xpressive -> xpressive gets built via CMake in depends -> CMake searches for install_name_tool on darwin -> Guix only has llvm-install-name-tool -> build fails. Bitcoin Core never hits this because it doesn't build any Boost components that go through CMake in the depends system?

[domob1812]

Ok thanks for the explanation, that makes sense.

ACK ccb1c90. Thanks!
