Replaces #13, which does not compile: getrandom 0.3 removed getrandom::getrandom.

Change

create_file_key fills the 32-byte file-key secret with getrandom::fill, the 0.3+ replacement. It reads the same OS source as before (getrandom(2) on Linux, getentropy on macOS), and an error still stops ck with "cannot generate a file key".

getrandom 0.2 stays in Cargo.lock as a transitive dependency of other crates; ck's own call is on 0.4.

Checks run locally

• cargo fmt --all -- --check, cargo clippy --locked --all-targets -- -D warnings
• cargo test --locked: all suites pass, including the run tests that create file.key
• cargo deny check: advisories, bans, licenses, sources ok
• cargo +1.85 check --locked --all-targets: rust-version unchanged

No user-facing change, so no docs change and chore(deps).

Kody Guide: Usage and Configuration

Interacting with Kody

• Request a Review: Ask Kody to review your PR manually by adding a comment with the `@kody start-review` command at the root of your PR.

• Provide Feedback: Help Kody learn and improve by reacting to its comments with a 👍 for helpful suggestions or a 👎 if improvements are needed.

Providing Context (Files & MCPs)

Add these hints in your PR description (or a comment) to unlock deeper checks:

• Ticket / Acceptance Criteria: `Refs: ABC-123` (Linear/Jira/Asana/ClickUp/Trello) or a direct ticket link.
• Bugfix Validation: a Sentry/Datadog/Bugsnag event link (or paste the stack trace/error message).
• Endpoint Risk: mention the route (e.g., `POST /api/payments`) or controller/action name.
• Attach a repo file as context: use an explicit marker like `@file:docs/guide.mdx#L10-L50` (replace with your real path).
• API Contract Docs: include `@file:openapi.yaml` or `@file:swagger.json` when changing routes/schemas.
• Definition of Done / Standards: include `@file:DOD.md` or `@file:CONTRIBUTING.md` if your repo has them.
• Design System Source of Truth: include `@file:ui/index.ts` (replace with your DS entrypoint path).
• Feature Flags: include the flag key/name and `@file:flags.ts` / `@file:config.json` (and optionally the PostHog flag name).
• Edge/CDN Rules: link the Cloudflare rule/zone or describe the intended redirect/header behavior.
• Attach an MCP tool output: use `@mcp<provider|tool>` (replace with an installed MCP provider + tool, e.g., `@mcp<sentry|events.search>`).

### [1/1] Cargo.toml:33
Issue identified during code review:
Breaking dependency upgrade in Cargo.toml: `getrandom` jumps from 0.2 to 0.4, crossing two semver-breaking releases of this security-critical randomness source, which changed the API and backend feature flags. Any remaining call to `getrandom::getrandom` fails to compile because 0.3+ renamed it to `getrandom::fill`, and wasm targets fail to build without the `wasm_js` backend feature. Fix: migrate call sites to `getrandom::fill`, enable the required target/backend features, commit the updated Cargo.lock, and attach `cargo audit` or OSV output for 0.4 to the PR.

Review each issue in context, use the reference implementations as guidance, and apply fixes that are consistent with the surrounding codebase.
