* RFC: Fine Grained Context Caching * Fix typos * Fix label * Add description of inject traits * Explicitly support context modification * Start implementation of context invalidation * Add inject trait variants * Route Extract / Inject traits to the proto nodes * Implement context dependency analysis * Implement context modification node insertion * Fix erronous force graph run message * Fix Extract* Inject* annotations in the nodes * Require Hash implementation for VarArgs * Fix nullification node insertion * Cross of done items unresolved questions section * Update Cargo.lock * Fix context features propagation * Update demo artwork * Remove BondlessFootprint and FreezeRealTime nodes * Fix migration * Add migrations for adding context features to old networks * Always update real time regardless of animation state * Cargo fmt * Fix tests * Readd sed command to hopefully fix profile result parsing * Add debug output to profiling pr * Use new totals instead of summaries for for iai results * Even more debugging * Use correct debug metrics (hopefully) * Add more MemoNode implementations * Add context features annotation to shader node macro * Cleanup * Time -> RealTime * Code review --------- Co-authored-by: Keavon Chambers <keavon@keavon.com>
