Add -r shorthand to SKIP_SESSION_ID check in claude wrapper (#1992)

* Add -r shorthand to SKIP_SESSION_ID check in claude wrapper

The wrapper checked for --resume but not its -r shorthand, causing
claude -r to fail with a --session-id conflict error because the
wrapper injected its own --session-id alongside the implicit --resume.

Fixes #1987

* Remove invalid -r=* pattern from SKIP_SESSION_ID check

Short options don't use the = form, so -r=* would never match a real
CLI invocation. Keep only -r as the shorthand for --resume.
