feat(integrations): add laravel-cloud Stripe catalog provider

[snowmead]

Summary

• Adds the laravel-cloud Stripe Projects catalog integration family as CatalogResource adapter(s).
• Follows docs/ADDING-A-PROVIDER.md and docs/PROVIDER-WAVES.md.
• Includes gap test + hermetic provision test. OUTPUT_FIELDS provisional until mise run discover.

Test plan

• Gap + hermetic tests in module
• Live mise run discover when provider is linked
• Merge after resolving additive registry.rs conflict with other family PRs

Note

Low Risk
Additive catalog integrations with offline tests and registry-only dispatch changes; provisional output envelopes are the main follow-up before live provision.

Overview
Introduces Laravel Cloud as a Stripe Projects catalog family with three managed CatalogResource adapters: laravel_cloud/application (laravel-cloud, outputs app_id), laravel_cloud/mysql (laravel-cloud-mysql, database_url), and laravel_cloud/valkey (laravel-cloud-valkey, redis_url). Each module follows the standard pattern—catalog-aligned config, validate_config, gap tests, and hermetic provision_script tests—with provisional OUTPUT_FIELDS until mise run discover.

Wires the family into register_providers!, providers/mod.rs, and extends the Hostable::OUTPUTS vs OUTPUT_FIELDS drift test for all three types.

stackless-provider-sdk gains int_optional, bool_required, and bool_optional for generated/catalog schemas that use non-string fields.

Documentation adds PROVIDER-WAVES.md (parallel Phase 1 landing, merge gates, exclusions), a catalog-first decision in DECISIONS.md, and a pointer from ADDING-A-PROVIDER.md. scripts/generate_catalog_integrations.py scaffolds future deployable adapters from catalog.json (Laravel Cloud entries included in its hints map).

This PR does not add a --on laravel cloud substrate or live smoke fixtures.

Generator skips implemented Laravel

Medium Severity

The same commit adds hand-written laravel_cloud adapters and a catalog generator whose IMPLEMENTED set still omits laravel_cloud/application, mysql, and valkey. Those refs appear in SHORT_PROVIDER and OUTPUT_HINTS but not in IMPLEMENTED, so running the script treats them as unimplemented and can rewrite the family and append duplicate register_providers! rows.
