Summary

• Rewrite man/shareData.Rd for issue docs: shareData() is read-once on POSIX but repeatable on Windows #89.
• Document the platform lifetime. On POSIX, getData() unlinks the object before unserialize(). A second call fails. On Windows, the mapping stays alive while the sharing session is alive. A second call succeeds.
• Document the map_name rules, the same-machine and same-user scope, the Linux /dev/shm limit, and the cleanup behavior.
• Keep the deep-copy explanation and the link to shareData() without deep copy? #43.

Test

• tools::checkRd("man/shareData.Rd") passes.
• git diff --check passes.

Closes #89.
