fix(app): isolate editor mode changes by tab

[murongg]

Summary

• route visual and source editor updates to the tab that produced them
• snapshot pending visual Markdown before source or split surfaces mount
• isolate source editor instances and pending shared-history baselines by document
• run CI for v2 pull requests and forward frontend test arguments correctly under pnpm 10
• add asset cleanup messages for every supported locale and align titlebar layout assertions

Why

Delayed IME completion and reused editor state could write through the currently active document after a tab or editor-mode switch. That could make source mode display or update content from the wrong tab.

Enabling CI for v2 also exposed missing localized asset-cleanup messages and stale titlebar expectations. The pnpm 10 test invocation forwarded an extra separator to Vitest, causing every App shard to run the complete test suite instead of its assigned files.

Validation

• targeted editor-mode and tab-isolation tests passed: 12 tests
• manual Tauri QA passed across preview, source, split, and two-tab round trips
• App workspace shards passed: 108 and 121 tests
• App remaining shards passed: 725 and 447 tests across 62 files each
• CodeMirror editor target passed: 33 tests in 1 file
• shared tests passed: 62 tests
• repository test typecheck passed
• app and shared builds passed
• diff checks passed

Risk

• source CodeMirror instances now remount when the active document changes; existing per-tab view-state restoration remains responsible for restoring editor position
• CI test commands now depend on pnpm forwarding matrix arguments directly without an extra separator
