rust-analyzer titles its check with the full command line, starting with the absolute path of cargo, so the status bar and Background Tasks popup showed /Users/…/Application Support/…/bin/cargo check … truncated before the useful part. LSP $/progress and DAP progressStart titles now go through ide_core::task::display_title, which turns a leading absolute executable path (with spaces, Windows drive/UNC, .exe/.cmd/.bat) into the program name.
Fixes#1060
