Update Cookbook docs: rename rustapi to rustapi-rs and add jobs learning path

[Tuntii]

This PR updates the RustAPI Cookbook documentation to ensure consistency with the current codebase version (0.1.275) and package naming conventions.

Key changes:

1. Package Renaming: Fixed multiple occurrences where the crate was referred to as rustapi instead of the correct rustapi-rs (in Cargo.toml dependencies) and rustapi_rs (in Rust imports). This affected recipes for file uploads, database integration, websockets, and handler concepts.
2. Learning Path Enhancement: Added a new "Background Tasks" section to the Learning Path in docs/cookbook/src/learning/README.md, guiding users to the rustapi-jobs crate for async processing in Microservices and Enterprise architectures.
3. Version Synchronization: Ensured that the updated documentation files reflect the current workspace version 0.1.275.

Pull request overview

Updates the RustAPI Cookbook documentation to align crate naming (rustapi-rs / rustapi_rs) with the current codebase and expands the Learning Path to include background job processing guidance.

Changes:

• Renames Rust imports from rustapi::... to rustapi_rs::... in multiple cookbook pages.
• Updates a Cargo.toml snippet to use rustapi-rs (and adds rustapi-jobs pointers in the Learning Path).
• Extends the Learning Path with “Background Tasks/Jobs” and references to rustapi-jobs.

• DefaultBodyLimit is not defined in the RustAPI crates (it looks like an Axum type). In RustAPI, request size limits are configured via RustApi::body_limit(...) (or by adding rustapi_core::middleware::BodyLimitLayer). Update this snippet to use the framework’s actual body limit API so the example compiles and matches runtime behavior.

use rustapi_rs::extract::DefaultBodyLimit;

let app = RustApi::new()
    .route("/upload", post(upload_file))
    // Limit request body to 10MB
    .layer(DefaultBodyLimit::max(10 * 1024 * 1024));

job-queue is introduced as a new example in the Microservices learning path, but it’s not referenced anywhere else in this doc (e.g., the “Examples by Category” or “Feature Matrix” sections). Either add it to those sections as well, or clarify that it’s a conceptual step (not necessarily an existing example project) to avoid confusing readers.

Suggested change

	| 6 | `job-queue` | Background processing, Redis/Postgres backends |
	| 6 | Background jobs (conceptual) | Background processing with `rustapi-jobs`, Redis/Postgres backends |
	> Note: The **Background jobs (conceptual)** step refers to using the `rustapi-jobs` crate rather than a standalone example project.

[Copilot]

The new content mixes the terms “Background Tasks” and “Background Jobs” for the same concept. Pick one term and use it consistently across the learning path and the enterprise table to reduce ambiguity.

Suggested change

	6. **Background Tasks**: Master [rustapi-jobs](../crates/rustapi_jobs.md) for async processing.
	6. **Background Jobs**: Master [rustapi-jobs](../crates/rustapi_jobs.md) for async processing.

The Cargo.toml snippet enables a multipart feature on rustapi-rs, but crates/rustapi-rs/Cargo.toml does not define a multipart feature. This dependency line will fail for users copying it. Remove the feature flag or replace it with the correct feature set (if any) needed for multipart support.

Suggested change

	rustapi-rs = { version = "0.1.275", features = ["multipart"] }
	rustapi-rs = "0.1.275"

rustapi_rs::extract::Multipart does not appear to exist in this codebase (there is no extract module exported by rustapi-rs). Multipart is already available from rustapi_rs::prelude::* (or via rustapi_rs::Multipart). Update the import to a valid path or drop it entirely to avoid a non-compiling example.

This example now imports rustapi_rs::prelude::*, but the dependency snippet only includes rustapi-ws (and not rustapi-rs). As written, users won’t be able to compile RustApi::new(), routing helpers like get, or the rustapi_rs import. Consider switching to the supported pattern: depend on rustapi-rs with features = ["ws"] and import WebSocket types via rustapi_rs::ws::{...} (or ensure both crates are listed explicitly).

[Copilot]

The dependencies list in this recipe does not include rustapi-rs, but the code sample imports rustapi_rs::prelude::* and uses RustApi/routing helpers. Add rustapi-rs = "0.1.275" (and any needed feature flags) to the Dependencies section so the example is copy/pasteable and compiles.
