refactor: remove unused optional arguments and fields

[JonasBa]

Hey folks, I'm working on an experimental CLI which uses the tsgo toolchain to find optional component and function signatures that are in practice never passed. This is essentially dead code elimination, and a complementary workflow to run alongside a tool like knip.

The changeset in this PR has been done using the script as the reporting tool, and an agent validator loop walking through each reported line one by one to first inspect the report, analyze the call sites, removing them, and later re-running ts. If done correctly, the code that has been removed should have been effectively dead.

The reporting script heavily relies on type quality and only reports on types whos members are statically enumerable.

I'm opening this PR in an effort to help you eliminate dead code, but also to gain feedback on the script and the detection mechanisms. There are always risks of false positive reports, and removal of code that is actually still required at runtime.

Some references of PRs opened to other repositories that have been merged or are still open:
✅ Sentry (4k loc removed)
⏳ Sentry (followup 1k loc removed)
⏳ Tanstack
⏳ npmx (this PR)

Would love to hear your feedback 🙏🏼

📝 Walkthrough

Summary by CodeRabbit

• Improvements
  • Simplified search and filtering behaviour for more consistent results.
  • Repository links now use standard default branches automatically.
  • Freshness scoring and repository metadata retrieval now follow consistent fixed settings.
  • Improved consistency across npm, authentication, caching and repository integrations.

Walkthrough

The changes remove configurable parameters from search, filtering, process, authentication, repository, provider, and chart utilities. The affected code now uses fixed query names, limits, branches, environment values, TTL handling, and freshness normalisation.

Changes

API Contract Simplification

Layer / File(s)	Summary
Search and filter contracts app/composables/npm/useAlgoliaSearch.ts, app/composables/useFacetSelection.ts, app/composables/useStructuredFilters.ts	Search requests use empty filters, maintainer searches limit results to 1,000, facet URLs use facets, and structured filters start from DEFAULT_FILTERS.
Runtime and authentication contracts cli/src/npm-client.ts, cli/src/npm-process.ts, server/api/auth/atproto.get.ts	Npm environment creation uses process.env, process command resolution reads process values directly, and random strings always use 16 bytes.
Repository and provider contracts shared/utils/constellation.ts, shared/utils/repository-meta.ts, shared/utils/git-providers.ts	Repository helpers stop accepting request options and TTL values. Provider URLs use fixed HEAD, main, or master branches.
Fixed freshness normalisation app/utils/compare-scatter-chart.ts	Freshness scores always use a 365-day normalisation period.
