Asserts that an unquoted UNC path like \\server\share\file.txt survives
extract_path_candidates unchanged, preventing the regression where
shlex.split(posix=True) stripped the backslashes.
Replaces the basic extraction test with an end-to-end test that verifies
UNC paths are correctly denied when outside the workspace (e.g. local root),
but correctly allowed when the workspace root is itself a UNC share.
Validates the fix from the PR review.
Adds explicit test coverage to ensure drive-relative paths (e.g. C:foo)
and escaped UNC paths (e.g. \\\\server\\share\\dir) from JSON payloads
are correctly validated by the workspace containment checks.
Closes final review suggestions.
load_session/save_session built the session file path directly from the
caller-supplied session_id with no validation, so a value like
'../../../tmp/secrets' (reachable from the 'load-session' CLI subcommand)
could read or write JSON files outside the session directory.
Add _validate_session_id() to reject anything outside [A-Za-z0-9_-]
(path separators, '..', absolute/Windows paths) before the id is used to
build a filename. Legitimate ids (uuid4 hex, 'session-<digits>-<n>') are
unaffected.
Adds SessionStorePathTraversalTests covering traversal rejection on both
load and save plus a legitimate-id round-trip.
