The cache bucket name was already limited to 63 characters in practice by Horde Storage. This makes it consistent across every cache store.

- Reading files from the Game Thread now launches a task to check and update the modification time, which approximately halves the latency of these reads.
- Writing files now only asks to delete the temporary file upon failure, as it added unnecessary latency before by trying to delete it after it was renamed.

- Added deletion of empty directories.
- Applied the rate limit to directory scans.
- Reduced the default scan rate by a factor of 10.

Except when replacing an existing value, load the existing value and check for determinism, and replace the existing value in the presence of an invalid value or non-deterministic value with missing content. This resolves move collisions being reported when a value existed without its content.

- Infinite misses break the editor in too many ways as we often rely on the local cache to be working correctly as off-memory storage.

- FileSystem, Http, Pak, S3 use the ValueWithLegacyFallback mode by default, which cause them to fall back to searching for uncompressed data if compressed data is not found.
- FileSystem has been fixed to store up to 1 MiB of compressed data inline with the value package rather than separately in content-addressable storage.
- Pak has been optimized to have GetChunks only load the required region of the requested value, rather than the whole value.
- Pak has been changed to stop storing data inline in the record package, since it will end up in the same file anyway when stored separately.
- Pak will upgrade the compressor and compression level when a compressed pak file is requested. Default cache compression uses Oodle Mermaid VeryFast and will upgrade to Oodle Kraken Optimal2.
- Zen does not have compression enabled by default, pending deployment of a new version that stores compressed values to Horde Storage.
- Added a missing request barrier when saving uncompressed data as compressed.
Example reduction in file system cache size when cooking for Windows:
- CitySample dropped from 66.5 GiB to 21.8 GiB.
- Lyra dropped from 2.54 GiB to 672 MiB.
- ShooterGame dropped from 1.21 GiB to 380 MiB.
Example reduction in compressed pak file cache size when cooking for Windows:
- CitySample dropped from 22.3 GiB to 18.5 GiB.
- Lyra dropped from 691 MiB to 543 MiB.
- ShooterGame dropped from 387 MiB to 313 MiB.
