chore: remove stale stash directory and unused type dependencies

[jonathannorris]

Summary

• Removes packages/js-ofrep-worker/src/stash/ directory containing dead code from the pre-flagd-core custom implementation (workers-storage.ts, json-logic-js.d.ts)
• Removes unused root devDependencies: @types/imurmurhash, @types/object-hash, @types/semver

These were leftovers from before the migration to @openfeature/flagd-core@^2.0.0. Nothing in the active source tree imports from stash.

Code Review

This pull request removes the custom Workers-compatible storage and evaluation implementation, along with its associated type declarations and several type dependencies including @types/imurmurhash, @types/object-hash, and @types/semver. The version of @openfeature/flagd-ofrep-cf-worker is also bumped to 0.0.2. I have no feedback to provide.
