feat(namespace): NO SPECIAL NAMES + storage fidelity — the ruled completion of the field-addressing law

The write side of the law, ruled 2026-08-03: data is either in main space
where developers can use anything, or it is in system.*.

- The reserved-name write door DIES: add/update/relate/updateRelation
  metadata bags accept EVERY name (confidence, type, id, data, level,
  content, ...) as ordinary user fields — indexed, filterable, sortable,
  aggregatable, identical to any other field. The remap/enforce/warn
  machinery, the reservedFieldPolicy config (now a typed init refusal),
  and the compile-time metadata key bans are all removed. The one write
  refusal left: keys spelled 'system.*' (namespace forgery), now enforced
  on all four write doors.
- STORED RECORDS GO NESTED (v2): engine fields top-level, the user bag
  nested verbatim under 'metadata', sealed by a format stamp — by-name
  storage discrimination is unsound once colliders are admitted. Legacy
  flat records stay readable forever through the shape-aware splitters
  (sound for them: the old door refused colliders). Time travel rides the
  same split (generation store snapshots whole records).
- Name-based index exclusions DIE: user frame indexes every name; the
  excludeFields/indexedFields knobs and their silent-[] holes are gone;
  bulk-payload protection is value-shape only, uniform across names.
- Consumer-sweep findings fixed in the same wave: per-type counts read
  the frozen 'system.type' column (addToIndex sort, affinity tracking,
  cold-count rehydration, VFS type bitmaps — legacy 'noun' fallback for
  pre-rebuild reads); resolveHiddenIds addresses 'system.visibility'
  (bare 'visibility' was a silent no-op under the law — VFS/system
  entities leaked into default reads).
- Fidelity fallout fixed in the owning layers: readEntityFieldAddress
  reads the bag first (colliders were absent-shadowed by its own guard)
  and never serves system addresses from the bag; blob history refs read
  the bag shape-aware; migration transforms now receive ONE normalized
  view (engine fields + nested bag) regardless of stored era, and stray
  flat-habit keys refuse with the fix in the message.
- THE REOPEN-COLLIDER CONFORMANCE CASE (required before any RC counts as
  gates-green): all ten collider names + plumbing names written as user
  fields, verified verbatim + queryable across live reads, flush+reopen,
  a forced epoch rebuild, and asOf time travel; relation mirror; forgery
  refusals; legacy flat-record compat. 8/8 green.

Gates: unit 1901/1901 (exit 0) · integration 758 (exit 0) · conformance
27/27 (exit 0) · consumer test sweep migrated (10 files).

* @description The canonical reserved-field contract ONE place that defines

* therefore never live inside a `metadata` bag.
* @description The stored-record layout contract ONE place that defines
* which keys of a persisted metadata record belong to the ENGINE (top-level
* entity/relationship fields) and how the USER's metadata bag is kept apart
* from them, faithfully, across flush / reopen / rebuild / time travel.
*
* Three layers enforce the contract, all driven by the constants below:
* THE FIELD-ADDRESSING LAW (ruled 2026-08-03, VENUE-BRAINY-ORDERBY-NOOP):
* data is either in main space where developers can use ANY name, and it
* all works with every database function or it is in `system.*`. There are
* NO reserved user-facing metadata names anymore: `confidence`, `type`,
* `level`, `data`, `id`, `content` inside a metadata bag are ordinary user
* fields. The only refused write is a user metadata key literally starting
* with `'system.'` (namespace forgery see `rejectForgedSystemKeys`).
*
* 1. **Compile time** `AddParams.metadata`, `UpdateParams.metadata`,
* `RelateParams.metadata` and `UpdateRelationParams.metadata` are typed so
* a literal reserved key is a TypeScript error (see
* {@link EntityMetadataInput} / {@link RelationMetadataInput}).
* 2. **Write time** for untyped (JavaScript) callers that smuggle a
* reserved key past the compiler anyway, every write path normalizes the
* bag: user-mutable fields are remapped to their dedicated top-level
* param (top-level wins when both are supplied) and system-managed fields
* are dropped with a one-shot warning naming the correct write path.
* 3. **Read time** every read path splits the stored flat record through
* {@link splitNounMetadataRecord} / {@link splitVerbMetadataRecord}, so a
* reserved field is surfaced ONLY at top level and `entity.metadata` /
* `relation.metadata` contain ONLY custom fields, always live reads,
* batch reads, and historical (`asOf`) reads alike.
* That law makes name-based storage discrimination unsound for NEW records
* (a user field named `confidence` may now legally sit beside the engine's
* confidence scalar), so persisted metadata records carry the user bag
* NESTED, shape-discriminated by a format stamp:
*
* Documented for consumers in `docs/concepts/consistency-model.md`
* ("Reserved fields").
* - **v2 (nested-bag)** `{ …engine fields…, [METADATA_RECORD_FORMAT_KEY]:
* NESTED_BAG_FORMAT, metadata: { user bag, verbatim } }`. Built ONLY by
* {@link buildNounMetadataRecord} / {@link buildVerbMetadataRecord}; the
* engine half and the user bag can never collide because they never share
* a level.
* - **legacy (flat)** engine fields and user fields mixed at one level,
* discriminated BY NAME through the RESERVED_* lists. Sound for legacy
* records precisely because the pre-law write door REFUSED user metadata
* carrying those names a flat key matching a reserved name IS the
* engine's value in any record the old door admitted.
*
* {@link splitNounMetadataRecord} / {@link splitVerbMetadataRecord} read
* BOTH shapes (stamp first, name split as the legacy fallback) and are the
* single read-side choke point for live, batch, AND historical (`asOf`)
* reads the generation store snapshots whole records, so time travel
* rides the same split.
*
* The RESERVED_* lists therefore no longer describe a user-facing ban they
* describe the ENGINE HALF of the stored record layout (and drive the legacy
* split). The write-door remap machinery and the compile-time metadata key
* bans that used to enforce the old contract are gone.
