…owser URLs and OAuth pages - Redact credentials in `debug config` output (upstream `82d4c89031`). - Open only http(s) URLs in the browser: shared `openUrl` in `@opencode-ai/core/open`, used by every browser-opening call site; MCP OAuth refuses non-http(s) authorization URLs (upstream `29f07e0c69`). - Escape provider-supplied error text on the Snowflake OAuth callback page (the escaping part of upstream `e8fea9e63a`).

- Line 2: Extend the secretName pattern in redactConfig to redact
credential-bearing keys such as AWS_ACCESS_KEY_ID, DOCKER_AUTH_CONFIG, auth,
passwd, and bearer. Match access-key variants, passwd, auth names ending at the
key or followed by config, and bearer while preserving existing matches; do not
match socket-path keys such as SSH_AUTH_SOCK.
- Around line 10-17: Update redactConfig to mask any non-null object or array
whose key matches secretName before recursively processing it; do not exempt
token keys. Preserve existing string redaction and leave numeric values
unchanged.

Fair point, but P3 and outside this backport. The URL is still in the sign-in notice for manual copy, so the user can recover. I'm noting it for a follow-up on the driver's timeout copy.

P2, below this PR's bar, so not fixing here: redaction masks string values, and non-string leaves under secret keys are left as-is (pinned by tests). A numeric secret in config would still print; I'm noting it as a follow-up rather than widening this backport.

Backports three hardening fixes from upstream v1.18 that we don't have, since we're based on v1.17.9. We are not doing another v1 merge, so we cherry-pick these instead.
debug configno longer prints secrets (starts from upstream82d4c89031, extended after review). Only the printed output is redacted; the resolved config used at runtime is unchanged.
