## Description
- This lead to a bug where if the folder name is in the form `a.b.c`:
- we check for:
`-home-coder-ai.coder.com/cd32e253-ca16-4fd3-9825-d837e74ae3c2.jsonl`
- But the actual file path for claude-session is:
`-home-coder-ai-coder-com/cd32e253-ca16-4fd3-9825-d837e74ae3c2.jsonl`
- The above bug might also occur in the case of `a_b_c`
- update workdir normalization to handle dot in path
