refactor(permission): consume structured bash payload

- require @gotgenes/pi-permission-system >=25.3.0 and read the complete local bash command from PromptPermissionDetails.payload instead of session-walking recovery
- remove the @sikongjueluo/pi-permission-shared package
- pass the triggering command unit to handlers via HandlerContext.unit in place of details.command
- add shadow-only AI judge modules for evidence projection, structured verdict requests, and prompt building, with vitest coverage
- record ADR 0004 and mark the ADR 0001 recovery mechanism superseded
- exclude pi-permission-system 25.3.0 from the pnpm minimumReleaseAge guard

 `pi-permission-inner-cmd` needs the complete Bash input before it may allow a transparent wrapper. `@gotgenes/pi-permission-system` exposes only the winning command unit as `details.command`; for `timeout 60s pnpm test && git push`, that may be `timeout 60s pnpm test`. An Authorizer `allow` approves the whole tool call, so unwrapping that unit alone could hide a sibling command.

+# Read the full Bash command from the structured prompt payload
+
+ADR 0001 recovered Pi's native Bash tool input by walking the captured session.
+That was necessary with `@gotgenes/pi-permission-system` 24.0.0, where an
+Authorizer received only the winning command unit as structured data.
+
+Permission-system 25.3.0 introduced a required, complete
+`PromptPermissionDetails.payload`. For a local Bash ask it represents:
+
+- `payload.request.value`: the command unit whose rule produced the ask;
+- `payload.request.executedUnit`: a display-only inner unit shown as `runs`;
+- `payload.evidence` entry labelled `full command`: the complete native Bash
+  input when it differs from `request.value`.
+
+The builder deliberately omits `full command` when the complete input equals
+`request.value`, so absence is a deduplication case rather than automatically a
+missing-evidence case.
+
+## Decision
+
+Require `@gotgenes/pi-permission-system >=25.3.0` and consume its structured
+payload directly. A command is eligible only for a local, native Bash payload:
+
+- `payload.kind`, `payload.request.surface`, `details.toolName`, and
+  `payload.request.toolName` all identify `bash`;
+- neither the legacy forwarding field nor structured requester marks it as
+  forwarded;
+- `payload.request.invokedToolName` is `null`, excluding shell aliases;
+- `payload.request.value` is non-blank and agrees with the legacy command
+  projection when that projection is present.
+
+Select the complete command as follows:
+
+1. Exactly one non-blank `full command` evidence entry: use its text.
+2. No such entry: use the non-blank `request.value`, relying on the 25.3 builder's
+   equality-deduplication contract.
+3. Duplicate, blank, inconsistent, forwarded, aliased, or malformed evidence:
+   defer fail-closed.
+
+`request.value` remains the triggering unit used to locate a transparent wrapper
+inside the complete input. An Authorizer verdict still applies to the whole tool
+call, so deterministic re-evaluation must continue to cover the complete
+unwrapped compound and all sibling commands.
+
+Forwarded asks in 25.3/25.4 remain out of scope. Their serving-side payload has
+kind `forwarded` and carries the child's legacy request prose as `requested`
+evidence; it does not preserve a separately structured child full command.
+Consumers must defer and must not parse that prose.
+
+## Consequences
+
+The session tool-call walker, its tests, and the
+`@sikongjueluo/pi-permission-shared` package are removed. Root session capture is
+still retained where needed for registration ownership and session-identity
+revalidation; removing command recovery does not make process-global service
+ownership safe by itself.
+
+The AI Judge can now call a model with the exact local Bash input without parsing
+UI text. Its initial integration remains Shadow-only: structured predictions are
+recorded as metadata and the Authorizer always returns `defer`.
+
+This supersedes only ADR 0001's session-recovery mechanism. ADR 0001's wrapper
+recognition, complete-compound re-evaluation, and fail-closed rules remain in
+force.

 Does the proposed six-cluster `JudgeRequestV1` contract contain fields that do not help the model decide whether to allow a Bash authorization request?
