Slumberpavilion: Moving archived DSH sessions out of the loading path

Sleeping Pavilion is a DSH memory plugin that physically relocates the log directories and projection records of archived sessions from `~/.dsh` to `~/DSH-Archive`, resolving the issue of records persisting in memory and consuming disk space after archiving. It features five built-in tools: `archive_list`, `archive_read`, `archive_session`, `archive_restore`, and `archive_delete`, supporting `dryRun`, multi-frame zstd decompression, and manifest restoration. It requires no configuration, is compatible with DSH versions >=0.2.1-rc.2 <0.4.0-0 and Node >=22.15.0, and is released under the MIT License.
