chore: add semver-major ignore for astro in Dependabot config

[JasonCust]

Summary

• Adds version-update:semver-major to the Dependabot ignore list for astro in .github/dependabot.yml
• Prevents premature major version upgrade PRs until the Starlight ecosystem supports the new Astro major version

Context

PR #188 (Dependabot astro 7.0.0 bump) failed CI because @astrojs/starlight@0.40.0 declares peerDependencies: { astro: "^6.4.5" } — no Starlight version supports Astro 7. The existing semver-minor ignore rule prevented minor bumps but allowed the major bump through.

Related

• chore: evaluate Astro 7 migration readiness #189 (new tracking issue for Astro 7 migration readiness)
• chore: remove npm override for @ascorbic/loader-utils when upstream adds astro 7+ support #26 (override for @ascorbic/loader-utils — verified still needed, no change)

Test plan

• npm run build succeeds (169 pages, exit 0)
• Dependabot YAML syntax validated
• PR chore(deps): bump astro from 6.4.7 to 7.0.0 #188 closed with comment
• Tracking issue chore: evaluate Astro 7 migration readiness #189 created with acceptance criteria

Add issue number to title: 'chore: add semver-major ignore for astro in Dependabot config (#188)' to comply with the required format.
Linked Issues check	⚠️ Warning	The PR changes ignore rules for Astro major updates, but issue #188 requires verifying Vite v8 compatibility, HTML compression behavior, compiler configuration, and Markdown processor functionality.	This PR only prevents the upgrade; address #188 requirements separately by performing compatibility verification, configuration updates, and comprehensive testing before attempting Astro 7 upgrade.

Lead Architect Review

Verdict: APPROVE (posted as COMMENT — GitHub prevents self-approval)

Surgically correct single-line configuration change that prevents doomed Dependabot PRs for Astro major versions until the Starlight ecosystem supports the target version. Root cause clearly identified (#188 failure mode), DECISIONS.md already documents the decision with removal condition, and tracking issue #189 exists for the deliberate migration.
