PR Summary

Medium Risk
Major-version upgrade of concurrent maps used on the HarPC networking path; compile/test CI is the main guard against API breakage.

Overview
Bumps the workspace scc (scalable concurrent containers) dependency from 2.4.0 to 3.0.0 in Cargo.toml, with Cargo.lock refreshed for the resolved graph (notably scc 3.8.3, new transitive saa, upgraded sdd, and assorted lockfile churn such as windows-sys / spin pins).

There are no application source changes in this PR; harpc-net and harpc-server remain the direct consumers (e.g. HashIndex, ebr::Guard, hash_index::Entry for in-flight RPC transaction tracking).

⚠️ Artifact update problem

Renovate failed to update an artifact related to this branch. You probably do not want to merge this PR as-is.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

File name: Cargo.toml

Artifact update for scc resolved to version 3.8.3, which is a pending version that has not yet passed the Minimum Release Age threshold.
Renovate was attempting to update to 3.7.3
This is (likely) not a bug in Renovate, but due to the way your project pins dependencies, _and_ how Renovate calls your package manager to update them.
Until Renovate supports specifying an exact update to your package manager (https://github.com/renovatebot/renovate/issues/41624), it is recommended to directly pin your dependencies (with `rangeStrategy=pin` for apps, or `rangeStrategy=widen` for libraries)
