fix(models): let a snapshot race resolve to the version that won

Two sends of the same request can both miss the content-hash lookup and race to
insert. The unique index settles it; the loser wants exactly what the winner
wrote, not an error that costs its response a version link.

+
+```shell
+YAAK_TARGET=web npm run dev --workspace @yaakapp/yaak-client

+That flag picks the browser host in `packages/platform/src/web/`, which answers

+engine. Data persists across reloads and is shared between tabs on the same
+origin. Sending HTTP is not available yet — the Send button reports that and
+everything else about the request is still saved. `packages/platform/src/web/README.md`
+lists which commands the browser host implements and which it declines.
+
+Desktop builds are unaffected: without the flag the platform package installs

+# Request versioning (IntelliJ Local History style)
+
+Working plan for `feat/request-versioning`. Tracks
+[save-request-data-for-response-history](https://yaak.app/feedback/posts/save-request-data-for-response-history).
+
+Selecting an old response should be able to show, and restore, the request that produced it.
+
+## Model
+
+One table, `model_versions`, versions every request type:
+
+| column | meaning |
+| --- | --- |
+| `id`, `model`, `created_at`, `updated_at` | usual model columns |
+| `workspace_id` | owning workspace |
+| `model_type` | `http_request` / `grpc_request` / `websocket_request` |
+| `model_id` | the request the version belongs to |
+| `content_hash` | sha256 of the canonical document |
+| `document` | JSON of the request's editable content |
+| `reason` | `send` / `switch` / `idle` / `restore` / `manual` |
+
+`http_responses`, `grpc_connections` and `websocket_connections` each gain a nullable
+`version_id`.
+
+A version's `document` is the model's JSON with bookkeeping keys removed — `model`, `id`,
+`createdAt`, `updatedAt`, `workspaceId`, `folderId`, `sortPriority`. One rule, applied the same
+way to all three request types; the hash is taken over exactly what the document holds, so moving
+a request between folders or re-sorting it never mints a version.
+
+`(model_id, content_hash)` is unique, so dedup is the database's job rather than a code path that
+can be forgotten. Sending an unchanged request ten times leaves one version and ten responses
+pointing at it.
+
+## Snapshot
+
+One primitive, `ClientDb::snapshot_request(request, reason)`: build the document, hash it, return
+the existing row for that hash or insert a new one, then prune. Everything calls it.
+
+- **Sends.** `resolve_send_inputs` (HTTP, every host — desktop, CLI, plugin-triggered) snapshots
+  before the response row is created, and the resulting id rides down to the response.
+  gRPC and WebSocket connect paths do the same at their own connection upserts.
+- **Edit-session boundaries the frontend can see**, all through one RPC: switching to another
+  request, window blur, app close, and a 60s idle timer after the last edit.
+
+Over-triggering is free, so the trigger code stays dumb.
+
+## Restore
+
+`restore_request_version(version_id)`:
+
+1. Snapshot the live request (reason `restore`), so anything newer than its last version is kept.
+2. Merge the version's document over the live model, keeping bookkeeping fields.
+3. Upsert. The written content's hash already exists, so no new version row appears.
+
+The frontend calls `wasUpdatedExternally` afterwards so open editors reload.
+
+## Retention
+
+An unreferenced version survives only while it is among the newest 50 for its request *and* newer
+than 30 days. A version referenced by a response lives as long as that response. Deleting a
+request deletes its versions. Versions are local history: not synced to the filesystem, not in
+Git, not exported.
+
+## UI (v1, HTTP)
+
+When the selected response's version differs from the live request, the response header grows a
+state-labelled dropdown ("Request Changed", following the GraphQL editor's pattern) with **View
+Diff** and **Restore**. The diff reuses the Git dialog's `DiffViewer` over YAML renderings of the
+two documents. No versions timeline panel in v1; gRPC and WebSocket are wired on the backend from
+day one and their UI can follow.
+
+## Status
+
+- [x] Migration + `ModelVersion` model + bindings
+- [x] Hashing / document extraction, with tests
+- [x] Queries: snapshot, prune, restore, cascade
+- [x] Send pipelines: HTTP, gRPC, WebSocket (plus the browser host's own)
+- [x] RPC commands + web/wasm host
+- [x] Frontend: snapshot triggers, dropdown, diff dialog, restore
+
+## Deliberately not in v1
+
+- **No versions timeline panel.** The only entry point is a response, which is
+  what the feedback asked for. A "browse all versions of this request" view is a
+  second feature on the same data and can land later without a schema change.
+- **No gRPC or WebSocket UI.** Both record versions from day one, so the history
+  is accumulating; only the indicator is HTTP-only.
+- **No `manual` trigger.** The reason exists so that adding a "Save version now"
+  action later is a UI change and not a migration.
+- **Folders, environments and workspaces are not versioned.** The response
+  timeline already records what a send inherited from them.
+
+## Notes for later
+
+- The version's `document` is the model minus bookkeeping keys, so a restore
+  merges over the live model and a field added after a version was captured
+  keeps its live value rather than being blanked.
+- `content_hash` sorts object keys before hashing. Relying on
+  `serde_json::Map` being a `BTreeMap` is not safe: `preserve_order` is on in
+  some builds of this workspace and off in others, which is exactly the bug the
+  `key_order_does_not_change_the_hash` test caught.
