Ship cross-toolchain support as layered PRs with explicit non-goals

Summary#

Complex platform additions are easier to stabilize when each PR adds one slice of capability and names what it intentionally does not solve yet. The uv workspace series in Turborepo separates discovery, native task execution, lockfile hashing, watch behavior, pruning, and integration coverage, which keeps review scope narrow and failures attributable. Agents should structure broad feature work as a dependency-ordered stack instead of one monolithic change.

Problem#

Adding a new workspace/toolchain model touches graph building, task execution, hashing, watchers, pruning, CI, and docs; bundling all of that at once makes regressions hard to isolate and review.

Solution#

Split the rollout into thin, composable PRs with explicit boundaries, preserve existing behavior at each layer, and add representative end-to-end fixtures only after the core slices are in place.

Failure Modes#

Monolithic PRs with unclear review scope
Hidden coupling between discovery, hashing, and watch logic
Premature feature claims before CI, docs, and fixtures catch up
