fix: rename root time-agent to time-agent-pkt to resolve name collision

Two agent files both declared `name: time-agent` with different implementations:
- `.claude/agents/time-agent.md` (root): PKT, UTC+5 (Pakistan Standard Time)
- `agent-teams/.claude/agents/time-agent.md` (agent-teams): Dubai GST, UTC+4

When both scopes are active, Claude Code may invoke the wrong time-agent —
serving PKT time when a Dubai command expects GST, or vice versa.

Renamed the root agent's `name` from `time-agent` to `time-agent-pkt` so
the two agents are unambiguous. The agent-teams variant retains `name: time-agent`
since `agent-teams/.claude/commands/time-orchestrator.md` explicitly invokes it
by that name for Dubai time display.
