* fix: session lost after evoscientist restart
* feat: Implement memory worker thread deletion on completion
- Added synchronous and asynchronous functions to delete memory worker threads after they finish execution, ensuring no residual checkpoints are left in the database.

* fix: support XDG_CONFIG_HOME for sessions.db on Windows
Fixes SQLite database opening failure on Windows systems with non-ASCII
usernames (e.g., Chinese characters). The get_db_path() function now
supports the XDG_CONFIG_HOME environment variable, consistent with
get_config_dir() in settings.py.
Closes#101
* fix: auto-resolve Windows Unicode path for sqlite3 via 8.3 short path
Refactor get_db_path() to reuse get_config_dir() (XDG_CONFIG_HOME
support) and add _to_short_path() helper that converts the config
directory to its Windows 8.3 short form via GetShortPathNameW. This
automatically resolves sqlite3 failures on Windows systems with
non-ASCII usernames (e.g., Chinese characters) without requiring
manual environment variable configuration.
The short-path conversion is best-effort: it targets the directory
(which exists after mkdir) rather than the db file, and falls back
gracefully on non-Windows, non-NTFS, or when 8.3 naming is disabled.
