  independently fixed the same bug class as our 07889a1/21964da41;
  adopted upstream versions (parentID === user.id for prompt exit, same
  findIndex boundaries for revert/session, isAfter helper in latest())
- v1.18.18 release (4 releases: v1.18.15-18)
- v1 database compatibility preservation (anomalyco#42444)
- ignore unknown config fields (anomalyco#41312)

- New models: GLM 5.3, Gemini 3.7 Flash, Grok 4.6, Zen updates

Fork-only changes preserved:
- Synthetic web search backend (synthetic flag in webSearchEnabled)
- Config npm propagation to inherited models
- Tool-result media extraction for models without attachment capability
- packageManager pin to bun 1.4.-canary.1 (Rust runtime)

Conflicts resolved: message-v2, prompt, revert, session, server-session
(adopted upstream), compaction (adopted upstream), registry + websearch
test (merged both synthetic + opencode-go).
