v2026.7.27

This release fixes now at start with --now (added in v2026.7.26) and adds early validation for future times.

Expressions like ypb download -i 'now/1h' --now 2026-07-26 ... previously failed because now at start was rejected. This is now fixed. Additionally, future start and end times now are rejected early at parse time for better error messages.

• Fix now at start rejection when --now is set

Changed
