- Simplified ptree API by removing spawnGroup and spawnAttached variants, consolidating into single spawn function.
- Replaced AsyncQueue class with simpler pushStream utility function for stream management.
- Refactored ChildProcess class to use AbortController instead of callback-based signal handling.
- Renamed captureText method to wait and execText function to exec for clearer API semantics.
- Removed mode parameter from exec function, eliminating distinction between spawn modes.
- Updated all call sites across coding-agent to use simplified ptree API.
- Added configurable ask timeout and notification settings to control ask tool behavior and user notifications.
- Added AskSettings interface with timeout (in seconds, default 30) and notification method properties to settings manager.
- Added ask timeout and notification configuration options to settings UI with values for timeout (off, 15, 30, 60, 120 seconds) and notification methods (auto, bell, osc99, osc9, off).
- Refactored process execution across multiple tools (exec, fetch, grep, read, youtube scraper) to use centralized ptree.execText() API instead of custom implementations.
- Refactored ChildProcess class in ptree to use public readonly properties and Promise.withResolvers() for cleaner exit handling.
- Migrated process spawning from `cspawn` to `spawnGroup` and `spawnAttached` APIs with explicit resource management using TypeScript's `using` statement.
- Refactored `ChildProcess` class to support process group management with new `isProcessGroup` getter and `[Symbol.dispose]()` method for automatic cleanup.
- Removed `cspawn` from public API exports in pi-utils, replacing it with `spawnGroup` and `spawnAttached` functions.
- Simplified `ChildProcess.kill()` method signature by removing signal parameter and eliminated `killAndWait()` method in favor of async disposable pattern.
- Converted `killChild` function to async implementation using Bun's `$` template and sleep-based polling for process termination.
- Removed Prettier configuration files (.prettierignore and .prettierrc) and migrated formatting to Biome.
- Updated Biome configuration from version 2.3.11 to 2.3.12 and changed arrowParentheses rule from 'always' to 'asNeeded'.
- Pinned @biomejs/biome dependency to exact version 2.3.12 in package.json and bun.lock.
- Applied consistent arrow function formatting across 489 files by removing unnecessary parentheses around single parameters.
- Removed blank lines after comment blocks and reorganized imports for consistency across the codebase.
