fix(acp): show command in permission dialog title

What does this PR do?

Make bash command visible in permission dialog in ACP mode.

Context: PR #32304 (fix(acp): show shell command in ACP tool calls) fixed this for the running state but not the permission dialog. This change closes that gap.

When OpenCode requests permission via ACP (e.g. in Zed), the dialog title is `bash` instead of the command string.

Root cause: acp/permission.ts sends title: permission.permission ("bash") to Zed's requestPermission call. The command string is only available as rawInput, which Zed renders after user response.

Fix

Add `permissionTitle()` to extract `metadata.command` (or `metadata.cmd`) for shell tools, so the dialog shows the command string in the approval prompt.

This mirrors the `toolTitle()` logic in `tool.ts` for running/completed tool call updates (landed in #32304).

How did you verify your code works?

Running it locally as ACP in Zed editor (v1.7.2)

• This PR appears to address a similar issue with ACP permission prompts and shell commands. It may have partial or related solutions to what you're fixing.

The current PR #32751 is specifically addressing a gap left by PR #32304 where the permission dialog title wasn't showing the command string. PR #28921 from earlier might have different or overlapping approaches to the same problem area that are worth reviewing to ensure consistency.
