TUI permission dialog can become stale: Enter confirm does nothing while /permission returns #28312

Description

Title:
TUI permission dialog can become stale: Enter confirm does nothing while /permission returns

Description:
OpenCode TUI can get stuck on a permission prompt even though the server has no pending permission requests.

Environment:

• OpenCode: 1.15.5
• OS: Linux 5.4.0-216-generic x64
• tmux: 3.2a
• TERM inside tmux: tmux-256color
• Client terminal: xterm-256color
• Running mode: opencode --port 9888, with additional opencode attach http://127.0.0.1:9888/ ... panes

Observed behavior:
The TUI shows:

Permission required
→ Read .env
Path: .env
Allow once / Allow always / Reject
enter confirm

Arrow/tab selection works, and Enter itself works elsewhere, but pressing Enter on the selected permission option does not dismiss the dialog and does not continue
execution.

Important diagnostic detail:
While the TUI still displayed the permission dialog, the local server reported no pending permissions:

GET http://127.0.0.1:9888/permission
=> < />< />

The server health endpoint was fine:

GET http://127.0.0.1:9888/global/health
=> {"healthy":true,"version":"1.15.5"}

This suggests the TUI has an orphaned/stale permission overlay whose backing permission request has already been resolved, cleared, denied, or otherwise disappeared from
server state.

Expected behavior:
If the displayed permission request no longer exists on the server, the TUI should dismiss the dialog or resync permission state instead of leaving a modal that cannot
be confirmed.

Actual behavior:
The stale permission dialog remains visible and blocks the user. Enter confirm is a no-op.

Workaround:
Opening a fresh opencode attach window to the same server/session bypasses the stale TUI state.

Example workaround:
opencode attach http://127.0.0.1:9888/ --session <session_id> --dir <project_dir>

Possible cause:
This looks like a lifecycle/state reconciliation bug between permission events and the TUI overlay state. The TUI appears to keep rendering a permission request after / permission no longer contains it. Similar to #14301 in spirit, but this happens in the terminal TUI/tmux attach flow rather than an ACP client.

Suggested fix:
On permission confirm, focus/resume, or attach, the TUI should refetch/reconcile pending permissions from the server. If the currently displayed permission ID is missing
from /permission, close the overlay and refresh UI state.
