fix(task): recognize child task references during validation

[nettlesh]

mise tasks validate now recognizes references to child monorepo tasks. For example, a root task with depends = ["//crates/gui:dev"] validates successfully when that child task exists, instead of reporting missing-dependency even though mise run dev succeeds.

The fix covers depends_post, wait_for, and structured run references, batches child discovery, and preserves child configuration errors. Task selection and counts, alias-check scope, and remote-file fetching remain unchanged.

Validation

Targeted e2e suites, scoped hk checks, and cargo clippy --workspace --all-features --all-targets -- -D warnings passed. Regressions cover missing/optional references, configuration errors, batched discovery, and validation scope. Scoped lint-fix also passed; repository-wide lint-fix reports the existing CHANGELOG.md size check and shellcheck autofix diagnostics (the shellcheck check passes).

Summary by CodeRabbit

Bug Fixes

• Improved task validation for monorepo configurations by resolving references within the correct project context.
• Prevented sibling project tasks and child-only validation issues from affecting root-level checks.
• Preserved support for aliases, relative paths, optional references, and dependency-related task reference forms.
• Added consistent diagnostics for missing task and dependency references.
• Ensured configuration-loading errors report their underlying cause during validation.
• Improved validation consistency across root, child-project, explicit-task, and all-task checks.

📝 Walkthrough

Walkthrough

The change updates task validation to preload monorepo-relative references through shared task contexts. It adds end-to-end coverage for validation scope, reference forms, loading errors, optional references, and shared loading.

Changes

Monorepo reference validation

Layer / File(s)	Summary
Reference catalog validation src/cli/tasks/validate.rs	Validation preloads unresolved cross-project references, shares the resulting catalog, and uses it for dependency and run-entry checks. Local and root references remain scoped to the local task map.
Validation scope tests e2e/tasks/test_task_validate_monorepo_references	Tests cover root and child validation counts, cross-project dependency traversal, selections, aliases, invalid child tasks, and remote files.
Reference form tests e2e/tasks/test_task_validate_monorepo_references	Tests cover valid, missing, and optional references across dependency, wait, and run-entry forms.
Loading error and sharing tests e2e/tasks/test_task_validate_monorepo_references	Tests verify that child configuration errors retain their causes and that multiple child scopes share reference loading.

Summary

This PR makes task validation discover explicitly referenced child-monorepo tasks without widening the set of tasks being validated.

• Batches unresolved cross-project references into one scoped task load.
• Applies the expanded catalog to dependencies, post-dependencies, waits, and structured run entries.
• Propagates child configuration-loading failures instead of misreporting missing references.
• Adds end-to-end coverage for validation scope, aliases, optional and missing references, load failures, and batched discovery.
