docs(roadmap): file PowerShell permission over-escalation as ROADMAP #50

PowerShell tool is registered as danger-full-access regardless of command
semantics. Workspace-write sessions still require escalation for read-only
in-workspace commands (Get-Content, Get-ChildItem, etc.).

Root cause: mvp_tool_specs registers PowerShell and bash both with
PermissionMode::DangerFullAccess unconditionally. Fix needs command-level
heuristic analysis to classify read-only in-workspace commands at
WorkspaceWrite rather than DangerFullAccess.

+50. **PowerShell tool is registered as `danger-full-access` — workspace-aware reads still require escalation** — dogfooded 2026-04-10. User running `workspace-write` session mode (tanishq_devil in #claw-code) had to use `danger-full-access` even for simple in-workspace reads via PowerShell (e.g. `Get-Content`). Root cause traced by gaebal-gajae: `PowerShell` tool spec is registered with `required_permission: PermissionMode::DangerFullAccess` (same as the `bash` tool in `mvp_tool_specs`), not with per-command workspace-awareness. Bash shell and PowerShell execute arbitrary commands, so blanket promotion to `danger-full-access` is conservative — but it over-escalates read-only in-workspace operations. Fix shape: (a) add command-level heuristic analysis to the PowerShell executor (read-only commands like `Get-Content`, `Get-ChildItem`, `Test-Path` that target paths inside CWD → `WorkspaceWrite` required; everything else → `DangerFullAccess`); (b) mirror the same workspace-path check that the bash executor uses; (c) add tests covering the permission boundary for PowerShell read vs write vs network commands. Note: the `bash` tool in `mvp_tool_specs` is also `DangerFullAccess` and has the same gap — both should be fixed together.
