Reconcile an existing Fizz harness with a changed source tree. Detects added/removed/changed contract functions, quarantines stale properties, regenerates drifted handler stubs, and refreshes the snapshot.

# Fizz Sync Skill — fizz-sync

Reconcile a project previously processed by the **Fizz** skill with a changed source tree. This is the re-use entry point: after the user modifies Solidity sources, `fizz-sync` detects drift, quarantines stale properties, regenerates drifted handler stubs, and refreshes the snapshot — WITHOUT re-running the full 11-step pipeline.

## When to use

- The source contracts under `src/` changed since `fizz` last ran.
- A property in `PROPERTIES.md` fails to compile or references a function that no longer exists.
- The user added new external functions they want fuzzed.
- The user wants a "is anything stale?" health check before re-running a campaign.

## Parameters

- `SUITE_DIR`: Solidity suite directory relative to project root (default: `test/fizz`). Use the same value that was passed to the `fizz` skill when the harness was generated.
