Command spans from the shell parser are sliced out of the script to display each command. These cases put multi-byte UTF-8 characters before span boundaries, where `vp run` currently panics or truncates the displayed command (voidzero-dev#719).

`brush_parser` reports source positions as character indices, but the command spans were used as byte ranges into the script. A script with a multi-byte UTF-8 character before a span boundary made `vp run` panic before running it, or display a truncated command. Convert the parser's character indices to byte indices before returning the spans. Fixes voidzero-dev#719 Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

The comment relied on an open brush PR that renames `index`. If a brush release switches to byte offsets without the rename, the unit test for multi-byte characters is what detects the double conversion. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>

Bumps vite-task from `9ba4cc9` to `8db455e`. Changelog: voidzero-dev/vite-task@9ba4cc9...8db455e#diff-06572a96a58dc510037d5efa622f9bec8519bc1beab13c9f251e97e657a9d4ed ## Breaking change adapted fspy no longer reports a bitset of access modes on each path. Each tracked operation is its own `PathAccess` (`Read`, `Write`, `ReadWrite`, or `ReadDir`). `vp_command` combines the operations that touch the same workspace-relative path into the existing `AccessMode` set, so the JavaScript `run_command` result is unchanged. ## User-facing vite-task changes - A mistyped task setting now fails with an error that names the field, instead of `data did not match any variant of untagged enum UserTaskDefinition` (voidzero-dev/vite-task#815). - `vp run` no longer panics on scripts that contain non-ASCII characters, and no longer cuts those commands off where it displays them (voidzero-dev/vite-task#861). - Reinstalling with another pnpm version no longer changes the cache fingerprint of `node_modules/.modules.yaml`; only whether the file exists is hashed (voidzero-dev/vite-task#850). - Cached tasks on Linux and macOS no longer abort when a program passes `-1` as a directory descriptor, and concurrent syscalls in tracked programs no longer overflow the stack (voidzero-dev/vite-task#862, voidzero-dev/vite-task#854). Docs are unchanged. These are fixes to existing behavior, and the guides do not describe the old error text or the `.modules.yaml` fingerprint. ## Validation - `cargo check --workspace --all-features --all-targets --locked` - `cargo clippy -p vp_command -p vite-plus-cli --all-targets --all-features -- --deny warnings` - `cargo test` for `vp_command`, `vp_error`, `vp_pm_cli`, `vp_js_runtime`, `vp_migration`, `vp_shared`, `vp_static_config`, `vite-plus-cli`, and `vp_global_cli` <div><a href="https://cursor.com/agents/bc-9c9cb178-3b56-4d68-9556-3028d946a3ec?cursor_ref=pr_footer&cursor_cta=open_in_web"><picture><source media="(prefers-color-scheme: dark)" srcset="https://cursor.com/assets/images/open-in-web-dark.png"><source media="(prefers-color-scheme: light)" srcset="https://cursor.com/assets/images/open-in-web-light.png"><img alt="Open in Web" width="114" height="28" src="https://cursor.com/assets/images/open-in-web-dark.png"></picture></a> <a href="https://cursor.com/automations/3a586a0e-cc2b-11f1-bec7-b2318963e0b6"><picture><source media="(prefers-color-scheme: dark)" srcset="https://cursor.com/assets/images/view-automation-dark.png"><source media="(prefers-color-scheme: light)" srcset="https://cursor.com/assets/images/view-automation-light.png"><img alt="View Automation" width="141" height="28" src="https://cursor.com/assets/images/view-automation-dark.png"></picture></a> </div> --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Charles Wang <wan9chi@users.noreply.github.com>

Motivation
The
vp runcommand panics before it runs a script that contains multi-byte UTF-8 characters, for exampleecho ああ. To display each command, the planner slices the script with the command spans from thebrush-parsercrate. These spans are character indices (SourcePosition::index), but the planner uses them as byte ranges. If an index falls inside a character, the slice panics. If an index falls on a character boundary, the planner displays a truncated command: it displaysecho あああasecho あ.The brush project tracks this bug in reubeno/brush#1127. The fix in reubeno/brush#1144 is still open.
Fixes #719.
Changes
vt_shellcrate converts the character indices from thebrush-parsercrate to byte indices before it returns the command spans. Each conversion counts characters from the start of the script, which takes about 0.2 µs for a 150-byte script.non_ascii_commandsfixture for plan snapshots.
