## Why
The TUI rejected playful `/goal` spellings such as `/goooooooooooal`,
even though Codex Apps accepts them for the World Cup promotion. This
keeps the TUI behavior consistent without changing how the canonical
command is presented.
## How it works
Built-in command lookup recognizes lowercase `go+al` as the existing
`goal` command after normal exact-name parsing fails. The command
catalog remains unchanged, so autocomplete continues to advertise
`/goal` normally.
## Verification
Added lookup-level and end-to-end TUI coverage for the flexible
spelling. The focused tests, scoped Clippy checks, and formatting pass.
The full `codex-tui` suite passed 2,833 of 2,835 tests; the two failing
guardian feature-flag tests reproduce unchanged on fresh `origin/main`.
