gitea/mod.nu had 6 `export use X *`. Each is now explicit.
Symbol counts per target:
api_client.nu 28
service.nu 10
workspace_git.nu 17
locking.nu 9
extension_publish.nu 6
commands.nu 24 (all multi-word "gitea X")
Total: 94 symbols, 24 quoted multi-word Nu subcommands.
Validation:
nu --ide-check 50 gitea/mod.nu -> 50 errors (all PRE-EXISTING)
Verified by stash-and-compare: the unmodified original mod.nu also
produced 50 errors from the same imported files. Zero errors
introduced by this refactor.
