deps: switch symfony/ai-* from stable workarounds when upstream fixes are released

[camilleislasse]

Context

Two upstream issues currently force us into workaround configurations:

1. Sylius / gedmo/doctrine-extensions — Loggable|object PHPDoc

PR doctrine-extensions/DoctrineExtensions#3046 (approved 2026-03-30 by @mbabker, not merged yet) removes the T of Loggable|object template that breaks symfony/type-info >= 7.4. Without that fix, any Sylius project where api-platform/symfony scans Gedmo classes crashes at cache:warmup (see Sylius#18878).

Workaround: pin symfony/type-info: ~7.3.0 and symfony/property-info: ^6.4 || ~7.3.0 to avoid the strict union check.

2. symfony/ai-bundle — ValidateToolCallArgumentsListener registration ✅ RESOLVED in v0.9.0

PR symfony/ai#2018 (merged 2026-05-04) fixes ValidateToolCallArgumentsListener registration when the symfony/ai-agent package is not installed. The fix is in dev-main but no stable release of symfony/ai-bundle includes it yet (latest stable = v0.8.0, released 2026-04-20).

Workaround: require symfony/ai-agent: ^0.8 in require-dev so the listener's referenced class exists (avoids lint:container failures).

Resolved in symfony/ai-bundle v0.9.0 (released 2026-05-16). Bumped in #27.

3. symfony/ai - #[SchemaSource] for runtime JSON Schema fragments

If symfony/ai#2024 (#[SchemaSource] for runtime JSON Schema fragments) is merged, re-evaluate whether the plugin's per-type FilterSchemaBuilder approach can be replaced or simplified by leveraging the native Describer chain (likely via per-grid virtual DTOs).

Action when upstream releases

When both of these are released:

• gedmo/doctrine-extensions >= the version that includes PR#3046
• symfony/ai-bundle >= a version that includes PR#2018 (probably v0.8.2 or later) ✅ done in v0.9.0

Then update this plugin:

1. Relax symfony/type-info from ~7.3.0 to ^7.3
2. Relax symfony/property-info from ^6.4 || ~7.3.0 to ^6.4 || ^7.3
3. Optionally drop the symfony/ai-agent: ^0.8 require-dev added as workaround ✅ done in chore(deps): bump symfony/ai-* to ^0.9 and drop ai-agent workaround #27
