Description

Part of #512 — pnpm workspace filter support.

Phase 3: src/utils.rs

Add package_manager_filtered_exec()

/// Build a Command using pnpm --filter <workspace> exec, or fallback to package_manager_exec.
/// When filter is present, always uses pnpm (workspace scoping only works through pnpm).
pub fn package_manager_filtered_exec(tool: &str, pnpm_filter: Option<&str>) -> Command {
    match pnpm_filter {
        Some(workspace) => {
            let mut c = Command::new("pnpm");
            c.arg("--filter").arg(workspace).arg("exec").arg("--").arg(tool);
            c
        }
        None => package_manager_exec(tool),
    }
}

Note on exec vs run: pnpm --filter web exec -- prettier runs the binary from node_modules/.bin. Correct for binaries (prettier, tsc, vitest, playwright, eslint, biome). For script-based commands, lint_cmd already resolves the binary name internally via detect_linter() before calling this function.

When pnpm_filter is None, falls back to existing package_manager_exec() — zero behavior change for non-workspace users.

Research direction
Review src/utils.rs to understand the existing package manager exec function. The issue provides a clear code snippet for package manager filtered exec, which returns a Command with pnpm filter when a workspace filter is provided. Note the distinction between exec and run for binaries. Testing should ensure the function works with both pnpm and fallback, and that no behavior changes for non workspace users.
