Preserve accessors with loose object spread

[tim-smart]

Summary

• preserve prototype accessors when packages are compiled with loose object spread transforms
• reorder base prototype spreads in Effect exits, AI models, SQL statements, and IndexedDB APIs
• add patch changesets for effect and @effect/platform-browser

Verification

• pnpm lint
• pnpm check
• pnpm --filter effect test --run test/Exit.test.ts test/unstable/ai/Model.test.ts test/unstable/sql/Statement.test.ts
• pnpm --filter @effect/platform-browser test --run test/IndexedDbDatabase.test.ts test/IndexedDbQueryBuilder.test.ts
• unmodified Expo reproduction: 9/9 tests pass with the makeExit reorder
• repository AST audit: no getter or setter remains after an object spread under packages/**/src

A native Object.getOwnPropertyDescriptor assertion was not added because it also passes with the broken ordering: standard object spread preserves the accessor in either position, while only Babel's loose transform loses it.

Consumer Workaround

Until this reaches a release, consumers can run a strict spread transform before babel-preset-expo:

plugins: [["@babel/plugin-transform-object-rest-spread", {
  loose: false,
  useBuiltIns: false
}]],
presets: ["babel-preset-expo"]

Closes EFF-114
Fixes #6578

📝 Walkthrough

Walkthrough

This change reorders shared prototype spreads and local accessors across core Effect, AI, SQL, and IndexedDB implementations. It also adds patch changesets for effect and @effect/platform-browser.

Changes

Prototype ordering updates

Layer / File(s)	Summary
Core primitive prototype ordering packages/effect/src/internal/core.ts, .changeset/polite-cameras-rest.md	makeExit defines its type, tag, and computed accessor before shared primitive properties; patch release metadata records the fix.
Effectable prototype composition packages/effect/src/unstable/ai/Model.ts, packages/effect/src/unstable/sql/Statement.ts, packages/platform-browser/src/IndexedDbDatabase.ts	Model, SQL Statement, and IndexedDB schema prototype fragments are repositioned without changing their described behavior.
IndexedDB query builder composition packages/platform-browser/src/IndexedDbQueryBuilder.ts	CommonProto is moved after the clear and clearAll accessors in the relevant prototypes.

Check name	Status	Explanation
Linked Issues check	✅ Passed	The prototype spread reordering matches the Babel loose-spread bug fix and targets the affected decode/encode path in #6578.
Out of Scope Changes check	✅ Passed	All code changes are limited to the prototype-order bug fix and release notes; no unrelated functionality was introduced.
