fix(hermes): read live WSL databases inside their distribution (#8254)

Windows SQLite cannot reliably read a live Hermes WAL database through a WSL UNC path. For wsl.localhost / wsl$ Hermes paths only, read the database inside the owning distribution via wsl.exe and Python SQLite (mode=ro, query_only, one short read transaction), streaming the result back in bounded JSON frames into the existing session projection. Non-WSL paths and macOS/Linux are unchanged. Requires python3 (3.7+) and timeout inside the distribution. Fixes #8205.
