Added @Override to execute() in 10 command files via parallel edits, then checked for test targets (none found) and verified the diffs.

[opencode-agent]

All 10 files updated. The cli subproject has no test target, so ant test is N/A — the change is purely additive (@Override, java.lang, no imports needed, no behavioral change).

Summary

Added missing @Override annotation to execute() in 10 command classes across cli/src/commands/.

Closes #466

Closing as duplicate of #471. Both PRs make byte-identical changes (same 10 file SHAs) for the @OverRide sweep on #466. PR #471 is preferred because it is based on the latest master (91d385c, includes the orchestrator + skill fix) and reports as MERGEABLE/CLEAN, whereas #470 is based on 5012ed8 and is now behind master. All work for #466 will be merged via #471.
