`cargo audit` flags rand 0.7.3 as unsound (RUSTSEC-2026-0097), and
permutation_iterator 0.1.2 is its sole importer. The crate is
unmaintained, so the finding is permanent for as long as we depend on
it.
Everything we used it for is "pick k distinct random indices out of n",
which is exactly `rand::seq::index::sample` from the workspace rand.
Switch the three src call sites and the two benches over, and drop the
dependency. 11 crates leave Cargo.lock.
Also fix a comment in quantile.rs claiming the permutation was
deterministic per count: the old crate keyed itself from thread_rng on
every call, so it never was.

* Unify parking_lot/arc_lock feature
* Move lib/common/{io,memory}/* -> lib/common/common/*
- Mmap-related items are grouped into `common::mmap` sub-module:
- `memory/src/chunked_utils.rs` -> `common/src/mmap/chunked.rs`
- `memory/src/madvise.rs` -> `common/src/mmap/advice.rs`
- `memory/src/mmap_ops.rs` -> `common/src/mmap/ops.rs`
- `memory/src/mmap_type_readonly.rs` -> `common/src/mmap/mmap_readonly.rs`
- `memory/src/mmap_type.rs` -> `common/src/mmap/mmap_rw.rs`
- Filesystem-related items are grouped into `common::fs` sub-module:
- `common/src/fs.rs` -> `common/src/fs/sync.rs`
- `io/src/file_operations.rs` -> `common/src/fs/ops.rs`
- `io/src/move_files.rs` -> `common/src/fs/move.rs`
- `io/src/safe_delete.rs` -> `common/src/fs/safe_delete.rs`
- `memory/src/checkfs.rs` -> `common/src/fs/check.rs`
- `memory/src/fadvise.rs` -> `common/src/fs/fadvise.rs`
- Rest is moved straight into `common`:
- `io/src/storage_version.rs` -> `common/src/storage_version.rs`
The old `io` and `memory` are now hollow crates that re-export items
from `common`. These hollow crates will be removed in next commits.
* Replace uses of `io` and `memory` with new paths in `common`
Since `io` and `memory` are just re-exports of `common`, these
replacements are no-op.
* Remove `io` and `memory` crates
* Quantization storage builder for chunked mmap
* fix after rebase
* Update lib/segment/src/vector_storage/quantized/quantized_chunked_mmap_storage.rs
