Bug: permission pathing crossplatform

[KoalaHao]

Description

      "permission": {
        "edit": {
          "*": "deny",
          "myPath/*": "allow",

this fails to match on windows, because the path would be myPath\*

OpenCode version

Steps to reproduce

1. windows
2. set edit permission to deny, set a specific path with forward slash / to allow, eg myPath/*
3. tell agent to edit a file in that path
   opencode denies edit
4. set path to back slash, eg myPath\*
   opencode allows edit to that directory

This issue might be a duplicate of existing issues. Please check:

• [FEATURE]: Limit tool (e.g. write, edit) permissions to specific folders #6318: Limit tool (e.g. write, edit) permissions to specific folders - addresses the same permission path matching functionality
• [FEATURE]: Add per-agent filesystem boundaries (allow/deny paths) + optional run-as user for bash #5529: Add per-agent filesystem boundaries (allow/deny paths) - includes similar path-based permission requirements
• Windows Support #631: Windows Support - umbrella issue tracking all Windows compatibility problems

This bug highlights a critical flaw in path-based permission matching when using forward slashes on Windows systems. The path normalization issue affects the core functionality requested in those feature issues.
