Pull Request Overview
This PR introduces a sub-2 second VM boot optimization system with a new performance module, an optimizer, prewarming/profiling utilities, a higher-level VM manager, CLI wiring, and extensive tests. It also updates the desktop app build config and multiple Svelte components to integrate with the new behavior and improve type safety.
- Add performance subsystem: optimizer (Sub2SecondOptimizer), profiler, prewarming, metrics/monitoring
- Add high-level Terraphim VM manager coordinating pools, optimizer, and monitoring; extend CLI
- Update desktop build/config and Svelte components; add extensive tests across REPL, VM, and hooks

desktop/src/lib/Editor/NovelWrapper.svelte:1
- This uses props and an extensions API that belong to the previous editor, not svelte-jsoneditor. JSONEditor expects a
contentprop and anonChangehandler; props like defaultValue, isEditable, disableLocalStorage, onUpdate, and extensions are not supported and will not work. Replace with svelte-jsoneditor's API (e.g.,content={{ text: html }}orcontent={{ json }}) and anonChange={({ text }) => html = text ?? '' }).

The Start command does not actually start the manager service; it just constructs a VM manager and exits. To match the CLI contract, initialize the high-level TerraphimVmManager and run it (awaiting the service loop).

Resource prewarming is entirely skipped, which can directly impact the boot-time targets. Wrap the optimizer in a mutex and prewarm during initialization, e.g. store optimizer as Arc<tokio::sync::Mutex> and call optimizer.lock().await.prewarm_resources().await? here.

The pool_size argument is unused; the method logs a size but doesn't use it to set target/min pool size or prewarm count. Either (a) apply it to update the pool's target or prewarm count, or (b) remove the parameter to avoid a misleading API.

These aliases point to Svelte's src runtime paths which are not part of the published package and will break resolution in a normal install. Use Svelte's public entry points instead (e.g. 'node_modules/svelte/internal', 'node_modules/svelte/store', and 'node_modules/svelte/index.mjs') or rely on bare specifiers.

Template references __saveStatus, but the state variable elsewhere in the component is named _saveStatus. This mismatch will break reactive status display and resets; change __saveStatus to _saveStatus consistently.

This block reads from configStore directly (and not its store value) and conflicts with the imported alias roleConfigStore. Use the store value ($roleConfigStore) instead of the store itself. For example: $roleConfigStore[$role] and pass the correct type guard.

_kgTermForModal is used in the template, but elsewhere the variable is referenced as kgTermForModal. This name mismatch will render as undefined. Use the same variable name consistently (e.g., kgTermForModal).

This module uses async_trait but the dependency must be declared for the terraphim_tui crate. Ensure async-trait = \"0.1\" is added to crates/terraphim_tui/Cargo.toml (not just the firecracker crate) to avoid a missing macro import at compile time.

[nitpick] Good fix switching from item.body.appendChild/removeChild to the document body. Consider also wrapping in try/finally to ensure the link element is always removed in case a.click() throws.
