fix(schema): allow structured task array entries

[risu729]

Splits structured task-array entries from #12521 into an independently reviewable schema change.

Change

The task parser accepts full RunEntry values inside task arrays, including task-reference tables with task, args, and env. The schema previously limited array items to strings. Point array items at the existing task_run_entry definition.

Scope

• Schema-only; no runtime behavior changes.
• Independent of the other fix(schema): align task dependency shapes #12521 split PRs and based directly on main.

No merge order is required.

Validation

• mise run render:schema
• Schema and Prettier checks scoped to schema/mise.json and schema/mise-task.json
• The original combined change passed mise run test:e2e e2e/config/test_schema_tombi and mise run lint-fix before splitting.

📝 Walkthrough

Walkthrough

The task schemas now allow task arrays to contain script strings, task references with optional arguments and environment variables, and parallel task groups through the shared task_run_entry definition.

Changes

Task schema updates

Layer / File(s)	Summary
Task array entry contract schema/mise-task.json, schema/mise.json	The task array item schema now references task_run_entry. The definition supports script strings, task references with optional args and env, and parallel task groups. The array description now reflects these supported entries.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to dc493

Task arrays can now validate structured task references and parallel groups alongside existing script strings. The schema changes are aligned across both published schemas, with no current merge-blocking risk identified.

Poem

A rabbit checks the schema bright
Scripts and task groups hop in sight
Args and env join the run
Parallel tasks race for fun
One shared entry keeps things right

Greptile Summary

This PR aligns task-array schema validation with the runtime’s existing structured RunEntry support.

• Allows task arrays to contain scripts, single-task references, and parallel task groups.
• Reuses the existing task_run_entry definition in both published schemas.
• Keeps the generated task-only schema consistent with its reference-driven definition ordering.

Confidence Score: 5/5

The schema-only change appears safe to merge, with no actionable correctness, security, or repository-rule issues identified.

The expanded schema variants map directly to the runtime’s accepted RunEntry variants, both JSON references are valid, and the generated task schema’s definition ordering matches the renderer’s traversal behavior.

Important Files Changed

Filename	Overview
schema/mise-task.json	Updates generated task-array items to reference the complete run-entry schema and relocates the newly reachable definition into generator discovery order.
schema/mise.json	Broadens task-array validation from string-only entries to the existing structured run-entry definition.
