feat: add interactive permission prompt UI to Inspector

Add permission request handling to the Inspector UI so users can
Allow, Always Allow, or Reject tool calls that require permissions
instead of having them auto-cancelled. Wires up SDK
onPermissionRequest/respondPermission through App → ChatPanel →
ChatMessages with proper toolCallId-to-pendingId mapping.

- Canonical extension namespace/domain string is `sandboxagent.dev` (no hyphen).
- Canonical custom ACP extension method prefix is `_sandboxagent/...` (no hyphen).
## Docs Terminology
- Never mention "ACP" in user-facing docs (`docs/**/*.mdx`) except in docs that are specifically about ACP itself (e.g. `docs/acp-http-client.mdx`).
- Never expose underlying protocol method names (e.g. `session/request_permission`, `session/create`, `_sandboxagent/session/detach`) in non-ACP docs. Describe the behavior in user-facing terms instead.
- Do not describe the underlying protocol implementation in docs. Only document the SDK surface (methods, types, options). ACP protocol details belong exclusively in ACP-specific pages.
## Architecture (Brief)
- HTTP contract and problem/error mapping: `server/packages/sandbox-agent/src/router.rs`

- `acp-http-client`: protocol-pure ACP-over-HTTP (`/v1/acp`) with no Sandbox-specific HTTP helpers.
- `sandbox-agent`: `SandboxAgent` SDK wrapper that combines ACP session operations with Sandbox control-plane and filesystem helpers.
- `SandboxAgent` entry points are `SandboxAgent.connect(...)` and `SandboxAgent.start(...)`.
- Stable Sandbox session methods are `createSession`, `resumeSession`, `resumeOrCreateSession`, `destroySession`, `sendSessionMethod`, `onSessionEvent`, `setSessionMode`, `setSessionModel`, `setSessionThoughtLevel`, `setSessionConfigOption`, `getSessionConfigOptions`, and `getSessionModes`.
- `Session` helpers are `prompt(...)`, `send(...)`, `onEvent(...)`, `setMode(...)`, `setModel(...)`, `setThoughtLevel(...)`, `setConfigOption(...)`, `getConfigOptions()`, and `getModes()`.
- Stable Sandbox session methods are `createSession`, `resumeSession`, `resumeOrCreateSession`, `destroySession`, `rawSendSessionMethod`, `onSessionEvent`, `setSessionMode`, `setSessionModel`, `setSessionThoughtLevel`, `setSessionConfigOption`, `getSessionConfigOptions`, `getSessionModes`, `respondPermission`, `rawRespondPermission`, and `onPermissionRequest`.
- `Session` helpers are `prompt(...)`, `rawSend(...)`, `onEvent(...)`, `setMode(...)`, `setModel(...)`, `setThoughtLevel(...)`, `setConfigOption(...)`, `getConfigOptions()`, `getModes()`, `respondPermission(...)`, `rawRespondPermission(...)`, and `onPermissionRequest(...)`.
- Cleanup is `sdk.dispose()`.
### TypeScript SDK Naming Conventions
- Use `respond<Thing>(id, reply)` for SDK methods that reply to an agent-initiated request (e.g. `respondPermission`). This is the standard pattern for answering any inbound JSON-RPC request from the agent.
- Prefix raw/low-level escape hatches with `raw` (e.g. `rawRespondPermission`, `rawSend`). These accept protocol-level types directly and bypass SDK abstractions.
### Docs Source Of Truth
- For TypeScript docs/examples, source of truth is implementation in:

- `server/packages/sandbox-agent/src/cli.rs`
- Keep docs aligned to implemented endpoints/commands only (for example ACP under `/v1/acp`, not legacy `/v1/sessions` APIs).
## ACP Protocol Compliance
- Before adding any new ACP method, property, or config option category to the SDK, verify it exists in the ACP spec at `https://agentclientprotocol.com/llms-full.txt`.
- Valid `SessionConfigOptionCategory` values are: `mode`, `model`, `thought_level`, `other`, or custom categories prefixed with `_` (e.g. `_permission_mode`).
- Do not invent ACP properties or categories (e.g. `permission_mode` is not a valid ACP category — use `_permission_mode` if it's a custom extension, or use existing ACP mechanisms like `session/set_mode`).
- `NewSessionRequest` only has `_meta`, `cwd`, and `mcpServers`. Do not add non-ACP fields to it.
- Sandbox Agent SDK abstractions (like `SessionCreateRequest`) may add convenience properties, but must clearly map to real ACP methods internally and not send fabricated fields over the wire.
