What broke

@evomap/dsh-evolver@0.3.0 does not load at all on any host with a commands service. evolver-status declared input: { hint: '' }, and dsh-commands rejects a present input whose hint is blank:

[E] [evolver] TypeError: command "evolver-status" input hint must not be empty
    at normalizeDefinition (.../@deepseek-ai/dsh-commands/lib/index.js:158:48)
    at Object.callback (.../@evomap/dsh-evolver/src/index.js:335:53)
    at new apply (.../@evomap/dsh-evolver/src/index.js:323:7)

That register runs inside the ctx.inject(['commands']) callback in apply, so the TypeError escapes apply and the whole plugin fiber fails: no recall priming, no turn reports, no skill provider, no commands. Nothing of Evolver reaches a session.

Only 0.3.0 is affected — 0.2.x built the hint from argument-hint and had no empty-string path.

The fix

A command that takes no argument omits input entirely.

The fake host in test/support/host.js accepted what the real one rejects, which is how this shipped green. It now mirrors normalizeDefinition's rules, so all eight definitions are validated at registration the way the host validates them.

Verification

• npm test — 182 pass.
• Putting input: { hint: '' } back fails 11 tests in apply.test.js with the production error, so the regression is covered.
• Every definition run through the real CommandRuntime.prototype.register from the installed DSH Desktop: all eight get past validation, and the same definition with the old input is still rejected with command "evolver-status" input hint must not be empty.

Needs a 0.3.1 tag to reach users.
