Publish official generator, testing, and package-manager integrations

[codeforester]

Parent: #214

Train position: 23 of 26
Phase: P3 — Ecosystem trust and broad adoption

Problem

Wide adoption will come faster by composing with established Bash generators, test tools, formatters, and package channels than by asking users to replace their workflows. Those integrations need pinned, maintained, optional contracts rather than informal recipes.

Acceptance criteria

• Ship and continuously test an official Bashly custom-library integration that preserves Base Bash initialization, lifecycle, bundling, and upgrade contracts.
• Publish tested Argc and Argbash interoperability recipes with exact argument boundaries, generated help ownership, and lifecycle responsibilities.
• Provide first-class Bats consumer helpers plus project-kit configuration for ShellCheck and shfmt without replacing those tools.
• Publish immutable verified packages or installation metadata for bpkg, Basher, and Basalt only where ongoing maintenance and integrity guarantees are sustainable.
• Pin supported upstream versions, publish a compatibility table, and make adapter breakage visible without adding mandatory dependencies to Core.
• Prepare and track accurate discovery submissions such as Awesome Bash after documentation, artifacts, and reference applications meet the release gates.

Dependencies

• Provide a declarative CLI contract with help, validation, and subcommands #228
• Ship project conformance checks and a reusable consumer test kit #231
• Ship pinned bundle, vendor, update, and verified release workflows #233
• Launch versioned documentation with a five-minute adoption path #236
