Ladda ner Lore Server 0.8.4

Changes since v0.8.3.
Features
- Add --dry-run to revision commit and lock acquire/release
- Run incremental store GC by default; replace --gc with --no-gc to disable
- Expose the mutable store through the low-level storage C API
- Add ForwardedRevisionService gRPC endpoint to forward BranchCreate to a remote server
- Carry structured error detail and FFI codes on the Complete event
- Show staged renames as moves in diff output
- lore status prints paths relative to the current working directory
Fixes & Improvements
- Fix use-after-free in write_fragmented when the chunker future is cancelled
- Fix LoreArray<T> dealloc layout mismatch in Drop
- Fix commit --stats panic and report real fragment stats
- Fix link contents surfacing as parent adds in file diff
- Fix clone not materializing view-filtered directories with all-excluded children
- Reject malformed metadata set args instead of panicking; default branch metadata to current branch
- Reset staged add/remove/update for link nodes
- Propagate dirty to committed ancestor directories on dirty add
- Make dirty add idempotent so a repeat dirty doesn't duplicate the node
- Stage empty dirty-added directories by their own path
- Honor --dry-run on branch push
- Rename [server.replication] config to [server.grpc_internal] (not backwards-compatible)
- Map GRPC storage errors correctly and stop classifying Unknown/EOF errors as server errors
- Handle thin-client RevisionDiff/RevisionTree RPCs with a zeroed revision
- Tag linked-repo RevisionDiff changes with an indexed partition table
- Standardise HTTP tracing and log levels
- Seed QUIC clients with an initial CWND on regeneration
- Remove redundant dry_run field from lock events
- Rename shared store config file to shared_store.toml with auto-migration
- Change stats flag to u8 for C ABI consistency
