fix(build): preserve native SQLite artifacts for Docker architectures

[iansherr]

Why this PR exists

Plugin testing in isolated Docker environments revealed that a server artifact built on one host could omit the native better-sqlite3 binaries required by another supported Docker architecture.

The existing build behavior was appropriate when artifacts were primarily used on the platform where they were produced. Cross-platform Docker testing introduced the requirement that the same server artifact remain deployable across supported Linux architectures and libc variants.

What changed

• Preserves Linux x64 and ARM64 glibc binaries in the server artifact.
• Preserves Linux x64 and ARM64 musl binaries for Alpine images.
• Keeps the existing host-target trimming behavior for other application builds.
• Adds explicit build-artifact verification for the four Docker-native SQLite binaries.
• Removes the build-check dependency on the general server test setup.

Validation

• pnpm --filter=server test-build — 4 build checks passed
• pnpm --filter=server verify-build-artifacts — 4 native artifacts verified
• pnpm --filter=server docker-build-debian
• pnpm --filter=server docker-build-alpine
• Debian container health check passed
• Alpine container health check passed

Scope

This PR is limited to server artifact composition and verification. Plugin-manager behavior and developer-harness changes are submitted separately.

Greptile Summary

The PR makes server artifacts portable across supported Docker architectures and libc variants.

• Retains x64 and ARM64 glibc and musl SQLite prebuilds in server distributions.
• Verifies required native artifacts during the normal packaging workflow.
• Adds focused artifact tests without the general server test setup.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains; both previously reported issues are fixed in the current code.

Important Files Changed

Filename	Overview
apps/server/package.json	The packaging workflow now verifies native SQLite artifacts before creating the server archive, resolving the prior verifier-bypass finding.
apps/server/scripts/verify-build-artifacts.mjs	The verifier checks all four Docker targets and now converts its module URL to a filesystem path correctly.
apps/server/scripts/build.ts	Server builds request retention of all supported Linux architecture and libc variants.
scripts/build-utils.ts	SQLite trimming supports preserving both Linux architectures while retaining existing host-target behavior by default.
apps/server/spec/build-checks/artifacts.spec.ts	Build checks explicitly assert that the required Docker-native SQLite binaries are present.
apps/server/vitest.build.config.mts	Build-artifact tests no longer load the unrelated general server setup.
