hush: --version reports 0.0.4 on both the broker line (main) and the pre-broker line (hush/0.0.x) #102

Problem

bws-tui/Cargo.toml says version = "0.0.4" on main and on hush/0.0.x. So hush --version prints hush 0.0.4 for two incompatible CLIs. The broker build on main has no get or --value, and its run and exec need the root broker daemon. The pre-broker build calls bws directly.

Evidence

• MacBook ~/.cargo/bin/hush --version: hush 0.0.4. It is a pre-broker build from a local path on Aug 18.
• aojdevlinux ~/.cargo/bin/hush --version: hush 0.0.4, built from e269d59 per ~/.cargo/.crates2.json.
• main at 65c21c2 and hush/0.0.x at 1e92b9b both have version = "0.0.4".

An agent cannot tell from --version which CLI contract it has. Found while fixing #101.

Decision needed

Choose the version numbers, for example 0.0.5 for the maintenance line after #101 and 0.1.0 for the broker line on main, and how fleet installs pin them. That is a release-policy call for the owner.
