docs(ocap-kernel): tighten snaps integration changelog entry

Drop the teardown-wiring bullet (internal hygiene, not a consumer
contract); merge the attenuation note into the "added endowments"
bullet with concrete user-visible deltas (10 ms timer floor,
monotonic Date.now); flag the DEFAULT_ALLOWED_GLOBALS → makeAllowedGlobals
rename as BREAKING.

 ### Added
 
 - Integrate Snaps attenuated endowment factories into vat globals ([#937](https://github.com/MetaMask/ocap-kernel/pull/937))
-  - Add `setInterval`, `clearInterval`, `crypto`, `SubtleCrypto`, and `Math` (crypto-backed `Math.random`) to the default vat endowments
-  - Swap raw `setTimeout`/`clearTimeout` and `Date` for attenuated versions from `@metamask/snaps-execution-environments`
-  - Wire factory `teardownFunction`s into `VatSupervisor.terminate()` so pending timers and other resources are released on vat termination
-  - Replace exported `DEFAULT_ALLOWED_GLOBALS` constant with `createDefaultEndowments()` factory and `VatEndowments` type; `VatSupervisor` now accepts `makeAllowedGlobals` in place of `allowedGlobals`
+  - Add `setInterval`, `clearInterval`, `crypto`, `SubtleCrypto`, and `Math` (crypto-backed `Math.random`) to the default vat endowments; `setTimeout`/`clearTimeout` and `Date` are now attenuated (10 ms minimum for timers; `Date.now()` monotonically clamped)
+  - **BREAKING:** replace exported `DEFAULT_ALLOWED_GLOBALS` constant with `createDefaultEndowments()` factory and `VatEndowments` type; `VatSupervisor` now accepts `makeAllowedGlobals` in place of `allowedGlobals`
 - Make vat global allowlist configurable and expand available endowments ([#933](https://github.com/MetaMask/ocap-kernel/pull/933))
   - Export `DEFAULT_ALLOWED_GLOBALS` with `URL`, `URLSearchParams`, `atob`, `btoa`, `AbortController`, and `AbortSignal` in addition to the existing globals
   - Accept optional `allowedGlobals` on `VatSupervisor` for custom allowlists
