chore: bump seo-graph-core to ^0.3.0 for transitive dedup (v0.4.2)

@jdevalk/astro-seo-graph@0.2.4 pins @jdevalk/seo-graph-core@0.3.0
as a direct dep. The plugin's previous `^0.2.0` range excluded
0.3.0 (pre-1.0 caret semver: ^0.2.0 means >=0.2.0 <0.3.0), so
consumers ended up with two parallel copies of seo-graph-core in
their node_modules — one for astro-seo-graph, one for this plugin.

Widening the range to ^0.3.0 lets both resolutions converge on
a single installed copy.

seo-graph-core 0.3.0 ships three additive improvements this
plugin doesn't currently exercise directly (no inLanguage default,
optional WebPageInput.breadcrumb, generic buildOrganization), so
no behavioural change in this plugin's output — strictly an
install-footprint fix.

Also bumps @jdevalk/astro-seo-graph range from ^0.2.1 to ^0.2.4
(^0.2.1 already satisfied 0.2.4, but pinning to the fixed
minimum makes intent explicit: use the rebuilt-with-pnpm-pack
manifest, not the broken workspace:* ones in 0.2.0/0.2.3).

+- Bump `@jdevalk/seo-graph-core` range from `^0.2.0` to `^0.3.0` and `@jdevalk/astro-seo-graph` range from `^0.2.1` to `^0.2.4`. This dedupes `seo-graph-core` in consumer `node_modules` — `astro-seo-graph@0.2.4` pins `seo-graph-core@0.3.0` as a direct dep, and the plugin's previous `^0.2.0` range excluded 0.3.0 (pre-1.0 semver), so consumers ended up with two parallel copies of `seo-graph-core`. They now resolve to a single copy.
+- `seo-graph-core@0.3.0` ships three additive improvements this plugin doesn't currently exercise directly: no more `inLanguage: 'en-US'` default on piece builders, optional `WebPageInput.breadcrumb`, and a generic type parameter on `buildOrganization`. No behavioural change in this plugin's output.
