Subject: [PATCH 1/3] chore(release): enter Changesets pre mode with the tag
 `next`

`pnpm changeset pre enter next` writes `.changeset/pre.json` as
`{"mode": "pre", "tag": "next"}`. From this commit, `changeset version`
computes prerelease versions and `changeset publish` publishes them under
the npm dist-tag `next`.

Subject: [PATCH 2/3] chore(release): one `major` marker so the v18 line opens
 at 18.0.0-next.0

Every publishable package is in the Changesets `fixed` group, which takes
the highest pending bump. Every changeset pending on main is `minor` or
`patch`, so pre mode alone would version 17.8.0-next.0. One `major` on
`@objectstack/spec` takes the group to 18; `sync-protocol-version.mjs`
reads PROTOCOL_VERSION from that package's major.

The changeset states its ADR-0087 disposition (not-required,
no-migration-prescription): the marker moves no authorable key, export,
type or stored shape.

+The v18 line opens (ADR-0131; #22050). Every release from here is an `18.0.0-next.N` prerelease on the npm dist-tag `next`, until 18.0 GA.

+- **What this marks.** Changesets is in pre mode with the tag `next`. Every `@objectstack/*` package versions together, so this one `major` takes all of them to 18, and the first version cut is `18.0.0-next.0`. `PROTOCOL_VERSION` follows `@objectstack/spec`'s major at version time, so it reads `18.0.0` from that prerelease on. The marker itself changes no code, key, export or stored shape.
+- **What the line carries.** ADR-0131 (organization ownership is total: no NULL `organization_id`) lands on this line in stages. Each stage that breaks something says so in its own changeset, with its own migration.
+- **Who receives it.** A plain install still resolves the dist-tag `latest`, which stays on 17.x until 18.0 GA. A prerelease is installed only on request: `@objectstack/spec@next`, or an exact `18.0.0-next.N`.
+- **What ends it.** 18.0 GA exits pre mode and publishes to `latest`.
+
+<!-- adr-0087: not-required (no-migration-prescription) the v18 line's opening marker: Changesets pre mode plus one major on the fixed group, so the train versions 18.0.0-next.N. No authorable key, spelling, export, type or stored shape moves in this diff, and no stored row is read, rewritten or converted; each breaking stage of the line states its own disposition in its own changeset. The other categories are closed on facts: the package publishes (not unpublished); no ADR-0087 id is named or touched (not registered or already-registered); and no TypeScript declaration moves (not runtime-interface-only or type-surface-only). -->

Subject: [PATCH 3/3] fix(scripts): name the consumed-prerelease exclusion as
 an `_EXCLUDED` constant

`check-adr-0087-registration.mjs` filters `.changeset/pre/` (consumed
prerelease changesets) out of its audit surfaces. The literal now sits in a
top-level `CONSUMED_PRERELEASE_EXCLUDED` constant that `isConsumedPrerelease`
reads; the literal and the predicate's match are unchanged.

The constant's name meets dispatch-gates' exclusion-declaration predicate, so
the watch-hint extractor reads the literal as the excluded surface it is.
Without it, once `.changeset/pre.json` is tracked the extracted hint
`.changeset/pre` resolves to `pre.json` under the PM self-test's loose rule
and not under its strict rule, and `check:pm-dispatch-gates` fails its
"extension narrowing costs no lead" case.
