Cache keys record absolute pnpm-store paths through `args`, so built-in-tool verdicts cannot cross machines

SpawnFingerprint normalizes cwd and the program to workspace-relative, collapsing an out-of-workspace program to its file name (crates/vite_task_plan/src/plan.rs:631-667, cache_metadata.rs:86-92), but args are keyed verbatim. When a user task's command is a vp built-in, the CLI's resolver returns an absolute binPath (oxlint, oxfmt, vitest, pack, vite) and it reaches plan_synthetic_request unchanged (plan.rs:546-577).

Under pnpm's global virtual store the key for vp lint --type-aware is program node_modules/.bin/node with args ['--disable-warning=...', '/Users/<user>/Library/pnpm/store/v11/links/@/oxlint/1.81.0/<hash>/node_modules/oxlint/bin/oxlint', ...], so no verdict replays between a CI runner and a developer checkout. In our monorepo that is 131 type-aware lint tasks whose cold lane takes about 5m39s; the same applies to vp fmt, vp pack and vp build tasks.

Request: fingerprint a core-resolved tool by identity (package name and version, which the core knows because it resolved the path), or relativize absolute args. The resolver also injects OXLINT_TSGOLINT_PATH into the key's tracked envs, whose value hashes a second store path, so args alone are not the whole key: replacing the built-in with sh -c 'vp lint ... "$@"' vp (no synthetic plan request, so neither the resolved path nor the resolver envs reach the key) is the workaround we landed, and the next run's miss message was env 'OXLINT_TSGOLINT_PATH' changed.

Separately, some recorded accesses in the entry value are a package prefix concatenated with an absolute path, e.g. tools/workspace-cache + /Users/<user>/<worktree>/tools/.../report.test.ts.mjs, which looks like a missed strip in auto-tracking.

Lies SpawnFingerprint in crates/vite_task_plan/src/plan.rs:631-667 und cache_metadata.rs:86-92, und verfolge dann plan_synthetic_request in plan.rs:546-577 für ein eingebautes Kommando wie vp lint --type-aware. Reproduziere den pnpm-store-Fall und untersuche die erfassten Umgebungswerte und aufgezeichneten Zugriffe; fertig ist es, wenn der resultierende Schlüssel und die Zugriffe nicht mehr von absoluten Store- oder Worktree-Pfaden abhängen und die Ergebnisse der eingebauten Prüfungen maschinenübergreifend wiedergegeben werden können.
