Commit Message

podspec: -exported_symbol for each FFI entry point

Release iOS builds had symbols present in the binary (-force_load
pulled the object code in; dSYM confirmed the code was there) but
dlsym(RTLD_DEFAULT, "LibwalletInit") returned NULL. Debug worked
because the debug dylib links with -rdynamic which exports
everything.

Cause: Xcode release builds strip the export trie for symbols that
nothing statically references, as part of dead-code elimination.
-force_load keeps the code; it does NOT keep the export trie entry.
dlsym searches the export trie, not the full symbol table, so the
code sits in the binary but is invisible to FFI.

Fix: pair -force_load with -exported_symbol _<name> for every
entry point from cshared/ffi.go:

  _LibwalletInit
  _LibwalletRequest
  _LibwalletSetEventCallback
  _LibwalletShowDebug
  _LibwalletDestroy
  _LibwalletFree

This forces ld to keep those specific symbols in the export trie
regardless of dead-strip, restoring dlsym on release builds while
preserving the DCE pass for everything else.

Also drafts the 0.4.0 CHANGELOG entry for the import/promote feature
that's been landing in the previous commits.

Reported against release testflight builds of a downstream app.
