fix(v0.5.1): use local time for workspace directory prefix and info display

Workspace directory names (YYYY-MM-DD_slug) and the YYYYMMDD-HHMMSS ID
field now use local time so users see their wall-clock date rather
than UTC — the prior behavior caused evening-EST creations to appear
under tomorrow's date for several hours every day. ctask info's
Created/Updated/Archived lines also convert to local for display.

Stored timestamps in task.yaml, session logs, the lease, the manifest,
and the session summary all continue to use UTC. Only user-facing
surfaces change.
