fix(schema): allow disabling automatic task outputs

[risu729]

Splits the task-output compatibility fix from #12521 into an independently reviewable schema change.

Change

The parser accepts outputs = { auto = false } and treats it as disabled automatic output tracking. The schema previously allowed only true; this models the full boolean contract and documents what false means.

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.

Related split PRs

• fix(schema): allow structured task array entries #12796 — structured task-array entries
• fix(schema): model ignored rust cache verify #12795 — ignored Rust-cache verification

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.

Greptile Summary

This PR broadens the task-output schema so outputs.auto accepts both boolean values and documents false as disabling automatic tracking.

• Updates both the full configuration schema and standalone task schema.
• The newly documented opt-out conflicts with runtime behavior when tasks inherit global inputs.

Confidence Score: 4/5

The PR is not safe to merge until auto = false reliably suppresses automatic output tracking or the accepted and documented contract is narrowed.

The schema now validates an explicit opt-out, but runtime deserialization collapses it into unspecified outputs and inherited inputs can turn automatic tracking back on.

Files Needing Attention: schema/mise-task.json, schema/mise.json

Important Files Changed

Filename	Overview
schema/mise-task.json	Allows outputs.auto = false, although runtime input expansion can subsequently reactivate automatic output tracking.
schema/mise.json	Mirrors the standalone task-schema change and exposes the same schema/runtime contract mismatch.

False Can Reactivate Tracking

When a task inherits nonempty global inputs without declaring its own sources, outputs = { auto = false } becomes an empty output list. Input expansion then treats the outputs as unspecified and enables automatic tracking. The schema therefore accepts and documents an opt-out that does not actually disable tracking for this configuration. The same issue is present in schema/mise.json:3278-3279.
