seo: add SoftwareApplication schema on homepage, enterprise, pricing, features

[vfanucci]

Summary

Adds a reusable SchemaSoftwareApplication.astro component and injects it on the four highest-traffic product pages: homepage, enterprise, pricing, and features.

Identified as priority 1 in the Agents Taskforce Pillar 1 audit — current site only emits Organization + WebSite (homepage) / BreadcrumbList schema. Without SoftwareApplication, AI agents and crawlers have to infer that Kestra is a software product instead of reading it directly.

What the schema declares

• @type: SoftwareApplication (+ @id: https://kestra.io/#software)
• applicationCategory: DeveloperApplication, applicationSubCategory: Workflow Orchestration
• operatingSystem, license (Apache 2.0), downloadUrl (GitHub repo)
• author / publisher references the existing Organization @id from layout.astro (clean graph linkage)
• offers: three tiers — Open Source (free), Cloud (pay-as-you-go), Enterprise (contact sales)
• Per-page name / description / url overrides to match page positioning

Files

• src/components/common/SchemaSoftwareApplication.astro — new reusable component
• src/pages/index.astro, src/pages/enterprise/index.astro, src/pages/pricing/index.astro, src/pages/features/index.astro — inject via existing <Fragment slot="head"> pattern (same as pricingSchema)

Test plan

• Build site locally and confirm no Astro errors
• Run https://search.google.com/test/rich-results on the 4 deployed URLs to confirm valid SoftwareApplication markup
• Re-run the agent-readiness audit and confirm SoftwareApplication is detected on all 4 pages
