chore(cli): remove accidental tui.json artifact from PR #13271

Removes packages/opencode/.kilo/tui.json, an empty {} file that was
accidentally committed by a broad 'git add' while running the httpapi
exerciser (PATCH /tui/config) from packages/opencode/ during work on
PR #13271 (feat(cli): add experimental MCP Apps support with
resource/tool HTTP endpoints).

Also ignores per-directory tui.json/tui.jsonc runtime config files
under packages/*/.kilo/ so this can't recur.
