chore: strip the comments this branch added

Removes every comment introduced on this branch: website/ in full, pages.yml
in full, and only the blocks added to ci.yml and release.yml — their
pre-existing comments are untouched.

Two directives survive because they are load-bearing rather than prose: the
triple-slash vite/client reference, and nothing else.

Two comments were carrying behaviour that the code did not state, so the
code now states it. useCopy's rejection handler clears the copied flag
instead of sitting empty, and writeTheme returns whether the write actually
landed instead of swallowing the failure in a bare catch. isExternal drops
its regex for two startsWith calls, which reads the same and no longer
hides a `//` inside a literal.
