What does this PR do?

Run 57 shared precomputed JSON fixtures through public getters, persistent cache restoration, and actual event records. Accept lossless numeric conversions regardless of the numeric wire label. Reject fractional Int reads, range overflow, and inexact Double conversion with TYPE_MISMATCH.

Motivation

Mobile SDKs need one response policy and automatic coverage when upstream cases are added. Ref: FFL-3568.

Additional Notes

Use pinned generated snapshots, integrity checks, a weekly draft update workflow, and module README instructions. No Git submodule or numeric capability is added. Upstream CI enforces generated plain/obfuscated fixture parity. Merge the canonical contract first.

Coverage includes valid and malformed obfuscation, native numeric boundaries, event identity, and exposure suppression. Unsupported variation types are isolated without rejecting valid neighboring flags. Device and live backend validation remain open.

This overlaps the converter changes in #4099, which still enforces the previous strict-type contract. Reconcile that overlap before merging either change.

Bundle size: The shared JSON corpus and runner live under reliability/single-fit/flags/src/test, outside the published Flags module. Inspection of the built release AAR, including its nested JARs, found neither the fixtures nor the runner. The additional test cases therefore add no fixture payload to customer app bundles. Runtime numeric fixes also change SDK code; the total binary-size difference was not measured.

Review checklist (to be filled by reviewers)

• Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• Make sure you discussed the feature or bugfix with the maintaining team in an Issue
• Make sure each commit and the PR mention the Issue number (cf the CONTRIBUTING doc)
