fix(build): write merged LICENSE directly instead of LICENSE.md (#1281)

The core and test packages were generating the full bundled-deps license
to LICENSE.md, then syncLicenseFromRoot() overwrote the plain LICENSE
with just the root MIT header. Since npm surfaces LICENSE (not .md) by
default, the merged content was invisible on npm/unpkg.

Now generateLicenseFile() writes directly to LICENSE and the redundant
syncLicenseFromRoot() is removed, matching how the CLI package already
handles it.
