On Windows, deleting an agent task together with its worktree failed with "os error 32" when the task's agent was still running. Agents that can't reload their session (`session/load`) stay running until the task is deleted. Deleting sent the kill and then removed the worktree right away, while the agent's processes still had the folder as their working directory and files in it open. `Peer::exited` now resolves once the child process has been killed along with what it started and has been reaped. Deleting a task waits for it (up to 5 s) before it removes the worktree. Removing the folder also retries for a few seconds while a file in it is still in use (a helper process that outlived the agent, an antivirus scan, the search indexer). Fixes #969.
The IDE you know, rebuilt in Rust.

Benchmark
Opening freqtrade (Python, ~770 files) with warm caches, median of 5 runs:
| OpenIDEA | IntelliJ IDEA 2026.2.3 | |
|---|---|---|
| Window with the project | 0.9 s | 3.1 s |
| Ready (CPU settled) | 1.1 s | 13.2 s |
| Memory (USS, all processes) | 169 MB | 2011 MB |
| CPU time until ready | 2.4 s | 47.9 s |
| Idle CPU | 4 % of a core | 7 % of a core |
| Quit | 0.3 s | 5.9 s |
A release build of OpenIDEA from main and IDEA with default settings and plugins, on
Windows 11, 32-core AMD, 62 GB RAM.
IDEA analyses Python more deeply, so "ready" doesn't mean the same work on
both sides. Both are measured from the outside, the same way: see
perf/compare to run it on your machine and projects.
