docs: upgrade Vellum to 0.3.0

[Tom Tang (qwerzl)]

Summary

• upgrade all Vellum packages from 0.2.4 to 0.3.0
• enable the new cell filter and TypeString.oneline support for Markdown-table-safe SDK types
• explicitly preserve Vellum 0.2's non-strict rendering behavior during the migration

Why

Vellum 0.3 replaces repeated table escaping chains with the profile-aware cell filter. The Eve integration page can therefore render its SDK-extracted option types with {{ option.type | cell | safe }} instead of maintaining five string replacements.

Compatibility

Vellum 0.3 enables strict Nunjucks rendering by default. The current synced Spectrum templates include a reference to an authoring symbol that is present on Spectrum main but not in the published spectrum-ts@12.0.0 package indexed by the aggregator. This PR sets strict: false explicitly to preserve the existing build behavior while gaining the additive table-cell helpers. Strict rendering can be enabled separately after the synced sources and published packages are aligned.

Validation

• pnpm install --frozen-lockfile
• pnpm docs:generate (662 symbols extracted, 85 templates rendered)
• isolated strict Vellum render of the local Eve integration page using cell (458 symbols extracted, two templates rendered)
• pnpm lint
• pnpm typecheck:docs
• git diff --check

Note

Low Risk
Dependency and docs-build config only; no runtime app logic. The explicit strict: false reduces risk of broken doc generation during the minor upgrade.

Overview
Bumps all @vellum-docs/* dev dependencies from 0.2.4 to 0.3.0 (with matching pnpm-lock.yaml updates, including new CLI transitives such as chokidar).

Updates vellum.config.ts to instantiate NunjucksEngine({ strict: false }) so doc generation keeps the prior non-strict Nunjucks behavior while on 0.3, which turns strict rendering on by default.

Poem

A rabbit bumps the docs with care,
Vellum grows a newer pair.
Nunjucks keeps its gentle ways,
Through templates, builds, and days.
Hop, hop—compatibility stays!
