Molten storage reliability upgrades, stronger task UX, and first full daily change pipeline.

Renamed project identity and docs from Codex Multiplexor terminology to Molten Code.

Improved task lifecycle behavior: completed-task minimization, explicit failure responses to callers, startup log cleanup, and agent profile visibility signaling.

Implemented initial Go CLI with gitlog/report packages, tests, CI workflow, and scheduled daily artifact workflow.

Documented command usage and artifact generation behavior in README.
