chore: repin Cargo.Bazel.json.lock The cherry-pick of #11090 ("fix: patch pcre2-sys for reproducibility") carried over master's `Cargo.Bazel.json.lock`, whose `checksum` is a digest over the crate_universe config and splicing manifest — i.e. over `bazel/rust.MODULE.bazel` plus every workspace `Cargo.toml`. Those differ between master and this RC branch (master has since bumped `comparable` to the dfinity fork, added `axum-otel-metrics`, `duration-string`, `exitcode`, bumped `canbench-rs` and `ciborium`, …), so the digest is stale here and every Bazel invocation fails at analysis time: Error: Digests do not match: Current Digest("987c09bb853448361351d6b167b9e528c23cea8fdaa95ce28b65cc3a9114fbce") != Expected Digest("4991a9aa71efd82294bf1844c7f4e677fc0fdad5c5d280d67766a7edd824e45b") The current `lockfile` is out of date for 'crate_index'. Regenerated with `./bin/bazel-pin.sh`. The resolved crate set was already correct for this branch, so the only change is the recorded checksum, which now matches the digest CI computes. `bazel query @crate_index//:all` passes again.

feat(registry): Enable blank replica_version_id for engines. (#10888) This is "just" a flag flip, but it suddenly makes a whole bunch of code active. # Future Work Existing engines cannot yet transition to blank replica_version_id. That will be fixed in an upcoming PR. # References [👈 Previous PR][prev] [prev]: #10885 --------- Co-authored-by: Daniel Wong <daniel.wong@dfinity.org>
feat(Core): Switch to deterministic memory tracker (#10789) This PR unifies page instruction charging. The deterministic memory tracker (DMT) now charges for all combinations of {heap, stable} x {read, write} page access types. The cost is uniform and increased to 5000 instructions per OS page (4KiB). Unchanged is the additional cost of copying dirty pages after the message execution (3000 instructions per page). So overall, the costs change like this: ``` previously dmt heap read: 0 5000 heap write: *1000 *5000 stable read: 0 5000 stable write: *1000 *5000 ``` * additionally charged for copy overhead after the message (+3000) The dirty stable pages tracking via the injected system API replacements is changed: The instruction counter is no longer decreased, because the DMT does it automatically. But the bitmap tracking of stable pages is kept, because it's still needed to limit overall stable memory access. As a consequence of this change, heap accesses are charged deterministically and immediately (during the message/slice, rather than afterwards), which means that messages with lots of heap accesses are DTS'd properly. While this incurs additional cycle costs, it will allow us to increase the Wasm heap size to much more than the current 6GiB limit.
