feat(run): style browser_execute in headless run mode like bash

[Alezander9]

Problem

In headless bcode run "..." mode, browser_execute tool calls render with the default gear icon and a duplicated tool name:

⚙ browser_execute browser_execute

The TUI path (session/index.tsx) already has a custom BrowserExecute component modeled on Shell, but the run-mode renderer (cli/cmd/run/tool.ts) had no entry for it and fell through to fallbackInline / fallbackStart.

Change

Adds a browser_execute entry to TOOL_RULES in packages/opencode/src/cli/cmd/run/tool.ts, mirroring the existing bash rule and the TUI BrowserExecute component:

• run → icon >, title = description ?? "Browser execute", block mode, body = streamed output on completion (parallel to runBash).
• scroll.start → # <description> followed by a prompted code block (> first line, continuations), matching the TUI renderer.
• scroll.progress → streamed console output, ANSI-stripped and trimmed.
• scroll.final → browser_execute completed [· <time>].
• permission → icon #, title = description, lines = prompted code.

Type plumbing: imports BrowserExecuteTool as a type-only import, adds browser_execute: typeof BrowserExecuteTool to ToolDefs.

Before / after

Before:

⚙ browser_execute browser_execute

After:

# Connect to local Chrome
> const session = await connect()
  const tabs = await session.getTabs()
  console.log(tabs)
[streamed output...]
browser_execute completed · 2.3s

Test

Verified locally on Windows by running:

bun --cwd packages/opencode --conditions=browser run src/index.ts run "..."

Output renders with the new styling on browser_execute calls and is unchanged on every other tool.

Notes

• Yellow-zone modification (upstream-vendored packages/opencode/src/). Will add a corresponding row to memory/browsercode/EXCEPTIONS.md in the agent repo alongside the existing TUI browser_execute Match-block entry.
• bun typecheck for this file passes; pre-existing missing-deps errors in packages/core/ (immer, ai-sdk/*) are unrelated to this diff.
