Fix 0.3.20 code-graph qualification for generated Go

[forhappy]

Summary

• raise the bounded parser-inspection ceiling so pack-specific budgets can distinguish large generated sources
• give go-web and the language-wide enterprise pack an explicit 200k syntax-node budget while retaining the 100k shared default
• record the qualification hardening in the 0.3.20 changelog

The existing compass-v0.3.20 tag has no GitHub release because its first workflow run failed this gate. After this PR is green and merged, the unpublished tag will be replaced with the corrected merge commit and the release workflow rerun.
