Allow users to pass custom build tags via `wails3 build -tags gtk4`
instead of requiring Taskfile modifications. Tags are forwarded as
EXTRA_TAGS to platform Taskfiles and appended to the go build command
alongside the existing production tag.
Works for both native and Docker cross-compilation builds.
Closes#4957

Update tests to match the new wrapTask behavior introduced in the
cross-platform build system:
- Task names are now prefixed with platform (e.g., linux:build)
- ARCH argument is automatically added based on GOARCH
- GOOS/GOARCH args are filtered from remaining args
- Environment variables are respected with arg overrides
Also adds test for the new SignWrapper command.
