Release 18.6 — Phase 1.3 + Phase 2

Tracking issue: #13468

Changes

  1. **\�ng/Versions.props**: Bump \VersionPrefix\ from \18.6.0\ → \18.7.0\
  2. **.config/git-merge-flow-config.jsonc**: Insert \�s18.6\ into the merge chain (\�s18.5 → vs18.6 → main)

Not changed (no-op)

  • \�s-insertion.yml: Auto-targets VS \main\ for all \�s*\ branches — no branch-specific mapping needed
  • \�s-insertion-experimental.yml: Already has \main/
    el/insiders/
    el/stable\ target options

Phase 1.3 + Phase 2: Update VersionPrefix to 18.7.0 and insert vs18.6 into the merge-flow chain.

Pull request overview

Updates MSBuild’s main branch versioning and merge automation to reflect the new VS 18.6 release branch and the next development version (18.7).

Changes:

  • Bump eng/Versions.props VersionPrefix from 18.6.0 to 18.7.0.
  • Extend the merge-flow chain so vs18.5 merges into vs18.6, and vs18.6 merges into main.

Phase 2 of the [18.7 release
checklist](#13639): bump `main`
to 18.8 now that `vs18.7` has been snapped.

### Changes
- `VersionPrefix`: `18.7.0` → `18.8.0`
- `PackageValidationBaselineVersion`: `18.6.0-preview-26180-08` →
`18.7.0-preview-26230-02`
- This is the 18.7 preview that was inserted into VS main via [DevDiv
VS#733906](https://devdiv.visualstudio.com/DevDiv/_git/VS/pullrequest/734784)
(msbuild commit `f215cd0f`), matching the prior pattern used in #13472
(which set baseline to the latest 18.6 preview at the time of snap).

### Notes
- `CompatibilitySuppressions.xml` files: not updated here. If ApiCompat
fails CI, run `dotnet pack MSBuild.Dev.slnf
/p:ApiCompatGenerateSuppressionFile=true` to regenerate.
- `azure-pipelines/vs-insertion.yml`: no `AutoInsertTargetBranch` field
on this version — no change needed for the main bump.
- `azure-pipelines/vs-insertion-experimental.yml`: already has
`main`/`rel/insiders`/`rel/stable` — no change needed.

Tracks #13639.
