Summary by CodeRabbit
WalkthroughThe pull request adds segment generation and Vite virtual modules, standardizes error wrapping with preserved causes, adds enum validation, updates lifecycle logging, changes example build directories, and expands package documentation. ChangesBuild and segment generation

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to Segment bundling can generate invalid imports for source paths containing apostrophes, and Windows middleware imports may be invalid. Lifecycle and CLI errors also lose stack-location diagnostics, reducing the ability to diagnose failures. These issues should be addressed before merge. Sequence Diagram(s)sequenceDiagram

If this pull request is only preparatory, link it to a more specific implementation issue and state that scope in the description.

In `@packages/jitar/src/cli.ts`:
- Line 20: Update the cli.start() rejection catch block to set process.exitCode
to 1 instead of calling process.exit(1), while preserving the existing
console.error handling and allowing pending writes and cleanup to complete.
In `@packages/logging/src/Logger.ts`:
- Line 121: Update Logger.#interpretObject to use the error stack when
available, falling back to object.message, before appending the formatted cause;
preserve the existing cause formatting behavior.
In `@packages/plugin-vite/src/index.ts`:
- Line 13: Add the required semicolon to the declaration of
APP_SEGMENT_RESOLVE_ID, preserving the existing value and surrounding style.
- Around line 124-153: Update the catch block in the load hook handling
APP_SEGMENT_RESOLVE_ID so failures from buildHelper.generateSegmentCode are
propagated to Vite instead of logging and returning null. Rethrow the original
error or wrap it with the segmentName while preserving the original error as
cause.
In `@packages/validation/test/Validator.spec.ts`:
- Line 22: Update every result.valid assertion in Validator.spec.ts to use exact

results, replacing truthiness-based assertions such as toBeTruthy() or
toBeFalsy().

Preserve the stack trace when formatting errors.
Logger.#interpretObject returns only object.message and the formatted cause. The CLI passes caught errors to logger.fatal, so failure logs omit file and line diagnostics. Use object.stack ?? object.message before appending the cause.
Suggested fix
+ const stack = object.stack ?? object.message;
const causeValue = object.cause !== undefined
? this.#interpretValue(object.cause, level + 1)
: undefined;
const cause = causeValue !== undefined ? `\n=>${causeValue}` : '';
- return `${object.message}${cause}`;

Keep exact boolean assertions.
Configuration and HTTP callers use validation.valid === false. A falsy non-boolean value could pass toBeFalsy() and bypass validation. Use toBe(true) and toBe(false) for every result.valid assertion.
