build.mcpp is C++ again, compiled by C++ Modules as the build program it is, and the project
view says when another C++ language service is answering the same files.

Changed

• build.mcpp is a cpp document. 0.6.0 gave it a language of its own, mcpp-build.
  VS Code prefers a filename match over an extension match, so that hid the file from C++
  Modules, which selects cpp: the build program got a line-by-line text check instead of a
  compiler. The mcpp-build language, its grammar and its language configuration are gone;
  this extension's build-script help now registers on cpp documents named build.mcpp, and
  the C++ module grammar is injected into source.cpp only.
• While C++ Modules serves build.mcpp, it answers what it answers better: the
  unknownSymbol check and the module names after import (completion and hover) are left to
  it. The SPEC-007 rule checks, the mcpp::… directive completion and hover, and the snippets
  stay. "Serves" means the extension is installed and enabled and mcppls.enable is not
  false here; the open files are re-checked when that changes.
• unknownSymbol reads the file's imports when it does run: import mcpp.rules.qt; makes
  mcpp::rules::… a name the snapshot cannot judge, so it is no longer reported
  (unknown mcpp::rules on every Qt build program).
• The diagnostics' owner is mcpp-build-script (was mcpp-build).
• The build-script snapshot and the mcpp.toml schema are regenerated from mcpp 2026.10.11.1.
  The schema generator reads the [build] keys from mcpp's key registry, where 2026.10.11.1
  moved them.

Added

• Project → Basics → Language service → "Other C++ language services". While C/C++
  IntelliSense, clangd or ccls is active next to C++ Modules, the row shows a warning and their
  names, and one click runs C++ Modules' own Turn Off Other C++ Language Services (it asks
  whether for this workspace or everywhere, and writes the other extensions' own settings).
  With none, the row is a dimmed check mark, "Only C++ Modules is serving C++". When C++
  Modules remembers what it turned off, the row's context menu offers Restore. The list is
  C++ Modules' own answer (0.0.16+); with an older one, a read-only look at the same three
  extensions.
• mcpp.languageServer.restoreConflicts ("C++ Modules: Restore Other C++ Language Services").
  mcpp.languageServer.manageConflicts is now titled "Turn Off Other C++ Language Services",
  which is what it always ran.

Migrating

• A setting written for the old language id, "[mcpp-build]": { … } in settings.json, no
  longer applies. Move it under "[cpp]".
• Turning other C++ services off or restoring them no longer asks a second time in this
  extension: C++ Modules' command asks where to act, and closing that question does nothing.
