fix: add getPty method to inlineCommand (#1080)

## Summary
- Adds the missing `getPty()` method to `inlineCommand`, delegating to
the underlying `internalCommand` via the `commandWithPty` interface
- Follows the same pattern already used by `inlineShellCommand` and
`terminalCommand`
- Enables PTY access for inline commands that need it

## Test plan
- [ ] Verify `runme run lint` passes
- [ ] Verify `runme run test` passes
- [ ] Confirm inline commands can access PTY when backed by a
PTY-capable internal command
