Provides AuthProfileStore, a thread-safe and process-safe JSON credential store using file locking for atomic reads and writes. It supports nested provider slots (e.g., 'claudeAiOauth', 'grokOauth'), automatic cleanup of expired fields, and deadline-aware writes. This module is independent of the rest of the application (only depends on standard library and a few local config path constants) and can be extracted as a reusable credential persistence utility for any application needing secure, cross-process credential management without a database.

Implements a robust XML tool-calling parser for LLM outputs. It extracts <function_calls>…<invoke>…<parameter> blocks, interleaves thought text, detects malformed or DSML-corrupted markup (e.g., Discord internal XML injection), deduplicates adjacent identical tool calls, and returns a structured ToolCallParseResult with valid/malformed/no_markup status. This module has no internal dependencies beyond standard library and a few shared types, making it directly reusable in any system that needs to parse tool calls from LLM responses.

Provides OAuthLoginDeadline, a context manager for timing OAuth login flows. It includes async browser opening, headless detection, and a deadline mechanism that raises an error if login exceeds a configurable timeout (default 5 minutes). The class is self-contained and can be reused in any OAuth implementation to enforce login deadlines.
