Regressions

Inside bench_icrc1_transfers the upgrade path got slightly more expensive, offset by larger wins elsewhere so the benchmark total still improved (u64 −6.65%, u256 −6.54%):

…c 1.95.0 The rustc 1.95.0 bump produces slightly larger wasm binaries and shifts deterministic execution estimates. Bump the compressed wasm size limits for ic-ckbtc-minter, sns-governance, and sns-swap, and update the hard-coded post-split load estimates in the subnet_splitting integration test. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Resolve conflicts for the rustc 1.95.0 bump: - Container image references (workflows, devcontainer, TAG): keep branch values; container-autobuild will rebuild and rewrite them on push. - canbench results (ckbtc minter, registry) and subnet-splitting test estimates: keep the rustc 1.95.0 values. Post-merge fixes: - subnet_splitting integration_test: update source/destination estimates to the measured orientation on the merged tree. - registry canbench: regenerate results.yml for master's registry code changes (values within ~3%).

github-actions

This pull request changes code owned by the Governance team. Therefore, make sure that
you have considered the following (for Governance-owned code):

Update unreleased_changelog.md (if there are behavior changes, even if they are
non-breaking).
Are there BREAKING changes?
Is a data migration needed?
Security review?

How to Satisfy This Automatic Review

Go to the bottom of the pull request page.
Look for where it says this bot is requesting changes.
Click the three dots to the right.
Select "Dismiss review".
In the text entry box, respond to each of the numbered items in the previous
section, declare one of the following:

Done.
$REASON_WHY_NO_NEED. E.g. for unreleased_changelog.md, "No
canister behavior changes.", or for item 2, "Existing APIs
behave as before.".

Brief Guide to "Externally Visible" Changes

"Externally visible behavior change" is very often due to some NEW canister API.

Changes to EXISTING APIs are more likely to be "breaking".

If these changes are breaking, make sure that clients know how to migrate, how to
maintain their continuity of operations.

If your changes are behind a feature flag, then, do NOT add entrie(s) to
unreleased_changelog.md in this PR! But rather, add entrie(s) later, in the PR
that enables these changes in production.

Reference(s)

For a more comprehensive checklist, see here.

GOVERNANCE_CHECKLIST_REMINDER_DEDUP

No canister behavior changes.
