fix(cli): keep init templates in sync

[alongubkin]

Summary

• add every example with template.toml to the versioned alien init catalog
• restore ai-quickstart-ts and ai-chatbot-ts, which were added in feat(examples): add an AI chatbot example over a private Postgres #271 but dropped when the catalog was made deterministic in feat: improve framework examples and operator packaging #428
• also restore the five other scaffoldable examples missing from the catalog
• add a test that compares the released catalog with all example metadata so they cannot drift again

Validation

• cargo fmt --all -- --check
• cargo test -p alien-cli commands::init::tests --lib

Supersedes the remaining unmerged part of #271. The chatbot example itself already landed in #428.

Greptile Summary

The PR restores seven scaffoldable examples to the versioned alien init catalog and adds a regression test intended to keep that catalog synchronized with example metadata.

• Adds the missing AI, storage, customer-key, customer-model, GitHub-agent, and Next.js templates.
• Compares catalog entries with examples containing template.toml.
• The new comparison does not fully enforce the directory-slug invariant used by archive extraction.

Confidence Score: 4/5

The PR appears safe to merge, with a non-blocking gap in the new catalog regression test.

The restored entries currently match their example directories, but the new set-based assertion can miss duplicate metadata names or metadata-to-directory mismatches and therefore does not fully prevent future catalog drift.

Important Files Changed

Filename	Overview
crates/alien-cli/src/commands/init.rs	Restores missing template entries and adds a useful synchronization test, but the test compares deduplicated metadata names rather than uniquely validating the directory slugs used at runtime.

### Issue 1
crates/alien-cli/src/commands/init.rs:658-662
**Catalog test ignores directory identity**
The test compares deduplicated metadata names rather than each example’s directory slug, even though archive extraction routes by that slug. Duplicate metadata names or a metadata-to-directory mismatch therefore pass this check while leaving a scaffoldable example unreachable.

For each issue above, determine whether it is valid and should be fixed. If so, fix it directly.
