feat: add st and stat aliases for issue status (CRY-50) (#128)

## Summary

- Adds `"st"` and `"stat"` to the `"issue"` entry in
`@subcommand_aliases` in `LinearCli.CLI`, alongside the existing `"s"`
alias
- All three aliases resolve to canonical `"status"` before Optimus ever
parses argv, so `lc i st`, `lc i stat`, and `lc issue status` behave
identically
- No existing aliases, flags, or command behavior changed

## Test plan

- [ ] `normalize_subcommand_aliases/1` unit assertions for both `["i",
"st", ...]` and `["i", "stat", ...]` in `cli_test.exs`
- [ ] End-to-end dispatch tests for `"issue", "st"` and `"issue",
"stat"` in `issue_commands_test.exs`, each verifying a full
status-change flow through `main/1` with a stubbed API
- [ ] All 48 tests in the two affected test files pass; 5 pre-existing
`GitTest` failures (environmental, unrelated to this change) confirmed
unchanged before and after
