DWAA1660andClaude Opus 5.5 c280506ba0 fix(config): isolate atomic writes and preserve long filenames
Create each atomic write through its own exclusively created temporary sibling and keep its open file handle until writing finishes. Concurrent writers publish complete files without truncating or following an existing temporary entry; failed writes or renames clean up their own staging file.

Keep the temporary basename bounded independently of the destination name so previously supported long project filenames still save. Retain the concurrent-writer and symlink regressions and add a 251-byte filename overwrite regression that checks exact bytes and staging cleanup.

Fixes #1233
