helmd v2: Go-server som styr agent i tmux — REST+SSE, frågedetektor, fildelning, ntfy, CI-release

- tmux som sanningskälla (agentoberoende, överlever omstart via adoption)
- API: sessions, prompt, question/answer, keys, mode, config, shares, notify, events
- frågedetektor testad mot riktiga agy 1.1.9-dumpar + mock
- integrationstest: 26 tester i isolerad debian-container (scripts/run-integration.sh)
- e2e-verifierad mot riktig agy (trust-fråga -> svar -> prompt)
- .gitea/workflows/helmd-release.yaml -> rullande helmd-latest (x64+arm64)
