0.68.0

A reference every writer checks needs no missing-row branch, and a view filter can compare with now.
9 added, 2 changed, 3 fixed.

Changed

• From format: ess/30 drop exists: false on a stored reference every writer checks and nothing deletes (#509).
• ess/30 suites re-read a kept reference's row after each branch writing either entity, so deleting it fails (#509).
• G1 grid O: from format: ess/30 a selector's where: may write coalesce(field, d) == v for an absent Optional (#627).
• From format: ess/30 an authored scenario may pin a {generated: true} value, which the suite checks exactly (#623).
• G4: from format: ess/30 an external: race narrowed by when_subject: may declare compensates: true (#623).
• G1 grid R: from format: ess/30 a view's filter: may order a Timestamp field against now, the instant of the read; generated Rust and Go view queries refuse it by name (#560).
• G2 grid R: from format: ess/30 the where: of instances: and of an affects: entry may read the row's lifecycle state (#564).
• 7 more in the changelog.
