A slug edit staged as `_slug` in a draft revision lands on the live slug column only inside repo.publish(), bypassing the uniqueness handling that guards direct slug edits. When the staged slug collided with another entry's (slug, locale), the UNIQUE constraint fired mid-publish and surfaced as an opaque 500 with a raw D1/SQLite message — after draft data had already been synced into the live columns. publish() now validates the staged slug before any write (against all rows, including drafts and trashed entries, since the unique index covers them) and throws an EmDashValidationError naming the conflicting slug and entry. handleContentPublish additionally maps a unique-constraint fingerprint to SLUG_CONFLICT as a backstop for the race window, matching create/update. Fixes emdash-cms#2034
Adversarial-review follow-ups: tag the pre-check error so publish maps it to the same 409 SLUG_CONFLICT as create/update (not a generic 400), write the slug before syncing data columns so a constraint hit in the race window leaves no partial publish on D1, and skip the check for NULL locales (unique indexes treat NULLs as distinct).

What does this PR do?
Publishing an entry whose staged slug (stored as
_slugin a draft revision) collides with another entry's(slug, locale)failed with an opaque 500 and a raw D1/SQLite message (D1_ERROR: UNIQUE constraint failed: ec_news.slug, ec_news.locale) — after draft data had already been synced into the live columns. The staged slug lands on the live column only insiderepo.publish(), bypassing the uniqueness handling that guards direct slug edits.This PR:
publish()before any write, against all rows in the entry's locale — including drafts and trashed entries, since the(slug, locale)unique index covers them. On conflict it throws a validation error naming the slug and the conflicting entry id, which the handler maps to the sameSLUG_CONFLICT(409) as direct slug edits in create/update.UPDATE(the only statement that can hit the constraint) runs beforesyncDataColumns— if a concurrent write takes the slug in the race window, no partial publish is left behind on D1 (which has no transactions to roll back).handleContentPublish's catch toSLUG_CONFLICTas a backstop for that race window, matching the existing create/update handling — a raw SQLite error never reaches the client.NULLlocale (unique indexes treat NULLs as distinct, so those rows can't collide).Closes #2034
