v0.5.2: accept config files from earlier versions

Version 0.5.2 fixes an upgrade failure in 0.5.1.

Versions before 0.5 wrote {"version": 1, "permissionMode": ...} to config.json in the state directory, the same file 0.5.1 reads for codexPath and computerUseAppPath. 0.5.1 rejected the unknown keys, so an upgraded install failed every Computer Use call with a config error. 0.5.2 ignores other keys and still checks that the two path keys are strings.

pi install npm:codex-computer-use-mcp@0.5.2
