AI summary

Before this PR, the hg-version: '3' legs of the release pipeline's integration tests ran Mercurial 6. There were three separate causes:

• Testing.csproj (since Use central package managment #1558, central package management): both branches of the MercurialVersion <Choose> were identical bare PackageReferences, so they resolved to the central versions. The hg 3 branch now pins SIL.Chorus.Mercurial to 3.0.3.11 with VersionOverride (NoWarn="NU1605", because LibChorus declares a dependency on Mercurial 6.5.1.43).
• dotnet test re-restores (older than Use central package managment #1558): the workflow builds with MercurialVersion=3 and then runs dotnet test. Without the property, dotnet test restores and builds again with the default 6, which re-stages hg 6 into backend/Testing/Mercurial*. Locally this left an hg 3.3 hg.exe loading an hg 6 fixutf8, which failed to import. Both test steps now pass the property.
• Windows legs: windows-latest runs steps in pwsh, where $MERCURIAL_VERSION is an undefined PowerShell variable, not the env var. So the build got /p:MercurialVersion= and fell back to 6. The input is now inlined as ${{ inputs.hg-version }}.

Guard against a repeat: the workflow sets TEST_EXPECTED_HG_VERSION from hg-version, and VerifyHgWorking (FlakyIntegration step) asserts that hg version reports that major version. The check is skipped when the variable isn't set, so local runs aren't affected.

LibChorus stays on the central 6.0.0-beta0074 in both legs. The old hg 3 pin, 6.0.0-beta0041, depends on SIL.Core 12 (we're on 18) and would be a downgrade: LfMergeBridge needs LibChorus ≥ beta0063, and ChorusMerge (via FwHeadless) needs beta0074. So this tests a hg 3 client binary with current LibChorus. Nobody has checked that this combination passes the integration tests yet.

What each leg resolves to (backend/Testing/obj/project.assets.json, plus bin/Mercurial/hg.exe --version):

Leg	LibChorus	Mercurial package	hg in ./bin
MercurialVersion=6 (default)	6.0.0-beta0074	6.5.1.43	6.5.1 (unchanged from develop)
MercurialVersion=3	6.0.0-beta0074	3.0.3.11	3.3

Known leftover: Testing now references FwHeadless (it didn't before #1558), and FwHeadless stages its own hg 6 into the same output. In the hg 3 leg, Testing's files win where paths overlap, but hg 6-only files (lib/, python39.dll) sit alongside. hg 3.3 runs and loads its extensions fine on Windows. I haven't verified this on Linux.

⚠️ Heads-up: release-pipeline.yaml already calls this workflow with hg-version: '3' on ubuntu-latest and windows-latest against staging. After this merges, those legs will start running real hg 3 for the first time in a long while, and they may go red. deploy-prod still runs when integration tests fail.

Test plan

• dotnet build LexBoxOnly.slnf -p:MercurialVersion=3, then dotnet test LexBoxOnly.slnf -p:MercurialVersion=3 --output ./bin (empty filter), from a clean state: assets resolve Mercurial 3.0.3.11, ./bin/Mercurial/hg.exe reports 3.3, and fixutf8 loads
• Same with MercurialVersion=6: LibChorus beta0074 / Mercurial 6.5.1.43, hg 6.5.1 (same as develop)
• hg version prints (version 3.3) / (version 6.5.1) on the two legs, so the (version {major}. check passes only on the matching leg; Testing builds
• Release pipeline hg 3 legs pass against staging (needs a live test server, so CI only)

Walkthrough

The integration-test workflow passes the selected Mercurial version to build and test commands and exposes it as an expected-version environment variable. The test project pins SIL.Chorus.Mercurial to 3.0.3.11 in the non-version-6 branch. VerifyHgWorking checks the reported version when an expected major version is set.
