Squash the current repository state back into one baseline commit while
preserving the README reframing and repository contents.

Constraint: User explicitly requested a single squashed commit with subject "asdf"
Confidence: high
Scope-risk: broad
Reversibility: clean
Directive: This commit intentionally rewrites published history; coordinate before future force-pushes
Tested: git status clean; local history rewritten to one commit; force-pushed main to origin and instructkr
Not-tested: Fresh clone verification after push

+/**
+ * Normalize camelCase `requestId` → snake_case `request_id` on incoming
+ * control messages (control_request, control_response).
+ *
+ * Older iOS app builds send `requestId` due to a missing Swift CodingKeys
+ * mapping. Without this shim, `isSDKControlRequest` in replBridge.ts rejects
+ * the message (it checks `'request_id' in value`), and structuredIO.ts reads
+ * `message.response.request_id` as undefined — both silently drop the message.
+ *
+ * If both `request_id` and `requestId` are present, snake_case wins.
+ * Mutates the object in place.
