  Epic 039 — build-triggered C# symbol indexing.

  SAFE TO COMMIT: the index step fires ONLY on machines where the indexer is installed
  (i.e. ~/.me-index/bin/ensure-ide exists, created by ide/src/RocketCoder/install.sh). On CI and on
  any machine without it, the target's Exists() condition is false → it never runs → zero impact.
  It is also ContinueOnError, so even a transient failure can't fail your build.

  On an installed machine a plain `dotnet build` auto-(re)indexes the project's symbols into the local
  IDE daemon (127.0.0.1:5179) via ensure-ide — no manual step, no flag. To opt OUT for one build:
  -p:IndexOnBuild=false. Override the daemon URL with -p:IndexHealthUrl=/-p:IndexUrl= if it moves.
