#4292 feat(harmonyos): support app uninstall beside deploy

Summary

HarmonyOS declared uninstall unsupported while deploy was supported, so reset-style QA flows kept reaching for raw hdc bm uninstall. The deployment facts now align: uninstall is available wherever deploy is, with the same device-kind gating, and the bm-uninstall path reports the message-shape quirk of bm outputs (this device answers bm dump misses with exit 0 and prose, so success detection keys on stream content, not exit codes).

5 files changed (deployment facts, uninstall leaf, tests).

Validation

• Head: 6541f8b6b on a68693c72 (includes review-fix commit grounded in a read-only device probe of bm exit-code behavior).
• pnpm run typecheck, pnpm run lint, deployment tests, integration-progress --check, fallow, freerange: pass locally.
• Independent cold review: 1 blocker fixed (exit-code assumption replaced by stream-content detection). CI runs the full gates on push.
