4.0.10 to 4.0.13 2026-09-10

Mentions: @git, @terminal and @symbol join @files, @problems and @workspace.
Terminal: fix the last error with the output attached, and write a command from a description, shown before it runs. Needs VS Code 1.93 shell integration.
Workspace index rewritten: an incremental index with a manifest, hybrid BM25 and vector search, a reranker in worker threads, @workspace or automatic mode.
Dependencies updated.
