test(go): resolve Box provenance by name

[walker-tx]

Summary

• includes the generated Box Go module sync from Sync Go module embed with guides #194
• resolves the Pulse ID as an alias and the display name Box as provenance
• replaces the machine-owned regen PR, which cannot be patched directly

Root cause

The provenance index is keyed by provenance.name. The normalized Box metadata uses locator: com.pulsemcp.mirror/box and name: Box, while the stale test expected the locator to remain a provenance name.

Test plan

• reproduced the original TestResolveAliasAndProvenance failure
• go run . generator: no drift beyond the intended test edit
• go vet . and go test .
• generator tests
• independent review: PASS
