Part 1/8 of the task-tree series (upstream-ready recomposition). Adds `depth` to HistoryItem and a cycle-safe `backfillTaskDepth()` that propagates parent depth through the delegation tree, so every task knows its nesting level. Depth is surfaced for later use by settings validation, environment details, and history-tree display. Includes the single-open-invariant spec mock for backfillTaskDepth (folded in from the series' CI fix) so this PR passes unit tests standalone. Depth contract hardening: - Children inherit their live parent's depth authority instead of assuming it, so a legacy non-authoritative parent never stamps its placeholder depth onto the child as a persisted fact (regression test added). - computeTaskDepth now processes an ancestor reached after exactly MAX_DEPTH_WALK hops; only strictly longer chains are rejected (boundary regression test added).
…ound-trip Part 2/8 of the task-tree series (upstream-ready recomposition). Adds two global settings that control subtask delegation: - `maxNestingDepth` (default 2, range 0-5): how many levels a subtask may nest. A value of 0 disables delegation entirely — every new_task runs inline. - `autoFlattenOnLimit` (default true): when the limit is reached, flatten the subtask into the current conversation instead of opening a new tab; when disabled such requests are rejected so you can continue directly. Full round trip: global-settings schema + defaults, ExtensionState, SettingsView control bound to cachedState with save payload, webviewMessageHandler persistence through ContextProxy, ClineProvider getState/getStateToPostToWebview, runtime consumers using the shared defaults. Includes focused tests for UI binding/save, persistence, and the saved value returned to the webview. Also completes the taskTree translation keys in all 17 non-English locales so check-translations passes standalone (folded in from the series' CI fix).

Adds a three-level new_task chain e2e (root -> child -> depth-2 task) where the depth-2 task's own new_task call exceeds maxNestingDepth and is flattened inline. Asserts exactly 3 tasks exist, the flattened work completes in the depth-2 task's own conversation, parent/child resume correctly, and the task stack never holds a fourth task. Hand-written aimock fixtures (no API key needed) use unique FLATTEN_E2E_ markers with predicate matching to avoid cross-suite collisions.

Part 4/8 of the task-tree series (builds on parts 1-3).
Description
Cancelling a parent task now cascades: live delegated children are interrupted so they do not keep running orphaned, and their delegation links are marked accordingly. The history tree surfaces each task's nesting depth.
