The discovery-alias info button explains the gate and links to the flag, but the
operator still had to assemble the Claude Code config by hand from the guide.
Render it instead, on the same Claude tool card, from the base URL the card has
already resolved (custom override included, normalized — no /v1, no trailing
slash), with a copy button.
The key slot holds a placeholder, never the real key: this card renders before a
key is necessarily selected, and a real key in copyable text is an easy way to
leak one into a screenshot or a pasted snippet.
buildClaudeDiscoverySettingsSnippet is a pure builder in claudeCliConfig so the
shape is unit-tested (7 cases, including that no `sk-` ever reaches the output
and that an invalid CLAUDE_CODE_AUTO_COMPACT_WINDOW is dropped rather than
emitted). Guide gains the matching section; the five new strings are translated
for pt-BR and vi (the locales with strict parity/marker tests) and marked in the
rest, per the repo's convention.
