Weekly usage / weekly reset day-time still not present in v4.0.0 (re: #167)

Title: Weekly usage / weekly reset day-time still not present in v4.0.0 (re: #167)

Body:

#167 was closed with a note that it was completed by #221 for the v4.0.0 release. Checked v4.0.0 (pipx install, claude-monitor 4.0.0) and the feature doesn't seem to be there.

• claude-monitor --help has no weekly view or weekly-reset option (no --view weekly, no reset-day/time flag).
• In claude_monitor/output/snapshots.py line 354, the code itself says:
  复制

  # seven_day is the OFFICIAL weekly slot, deferred until the statusline keystone

  So the weekly slot is explicitly deferred, not shipped.
• Confirmed the v4.0.0 tag and 6a199f3 (release-doc prep commit mentioned in the #167 closing comment) are both ancestors of the current main/v4.0.0 — so this is checked against the actual released code, not a stale build.

Could you confirm whether weekly usage / weekly reset day-time is planned for a later release, or if it did land somewhere I'm missing?
