Describe the contribution

• Fixes Add break; for switch default case in LC_VerifyMsgLength() #77
  • Adds a break statement to the default case of the switch block.

Testing performed
GitHub CI actions (incl. Build + Run, Unit Tests etc.) all passing successfully.

Expected behavior changes
Purely a style/guidelines issue for consistency and future maintenance.
No change to logic (the default case would fall through to the bottom and exit the switch block even without a break statement).
Guidelines and cFS consistency dictate that all switch cases (including default) should be terminated by an unconditional break statement.
