PR Review: bump actions/setup-dotnet v5 to v6

Summary: Straightforward Dependabot dependency bump. All 20+ actions/setup-dotnet@v5 references across ci.yml and codeql-analysis.yml are updated to @v6. No source code is touched, so the usual quality/bug/perf/security concerns do not apply here — the review reduces to: is the major-version bump safe?

What is good

• Consistent and complete. grep confirms zero remaining @v5 references. Even the commented-out RocketMQ job block was updated, which keeps it accurate for whenever it is re-enabled.
• No input changes required. The v6 breaking change is internal (migration to ESM + dependency upgrades per the v6.0.0 release notes: https://github.com/actions/setup-dotnet/releases); the dotnet-version: multiline input syntax used throughout is unchanged, so no config migration is needed.

Things to confirm before merge

• This is a semver-major bump, so the real gate is green CI. v6 raises the action Node runtime (ESM migration) — GitHub-hosted ubuntu-latest runners support this, but it is worth watching the first run across the matrix (build, test, packaging, and the CodeQL job) to be sure no cached/older runner behavior surfaces.
• Since this changes the toolchain-setup action used by essentially every job, a full CI pass is sufficient verification — no additional testing needed.

Minor (pre-existing, out of scope — not introduced here)

• In codeql-analysis.yml the step is named "Setup dotnet 6.0.x" but installs 8.0.x. This predates the PR; flagging only for future cleanup, not as a blocker for this change.

Verdict: Safe to merge once CI is green. No code, style, or security concerns within the scope of this diff.
