refactor(downloader,repository,json): drop stale try/catch TODOs; fix svn getFileContent catch type

Remove 17 TODO(phase-b) markers across exception-modeling sites where the
existing single-Result closure+match already faithfully models the PHP
try/catch (catch paths only rethrow, retry, log, or silently ignore and
never yield a recoverable value, so a double Result is unnecessary).

Fix SvnDriver::get_file_content to catch only RuntimeException (matching
PHP's catch RuntimeException) and extract its .message instead of calling
e.to_string() on the anyhow::Error, which would panic while the shim
exception Display is unimplemented; other errors now propagate.
