Match the retired mise tool exactly in the global listing

Whether the environment mise built is gone was read by searching the global listing for the prefix `"pipx:hermes-agent`, so a tool that merely starts the same way, `pipx:hermes-agent-tools` say, read as the retired one still requested. Removing the real one changed nothing, the recheck failed again, and the migration stayed pending on every update. The key is matched whole now, with or without its options.
