Trebell Code 1.3.2

Version 1.3.2 is a repository and release-hardening update built on Trebell's current multi-harness desktop architecture.

Repository cleanup

Promoted the actual Trebell Code application to the GitHub repository root.
Removed the obsolete upstream Codex source tree from the Trebell repository root.
Added goal.md to the repository as the product/architecture contract.
Added an ignored release-artifacts folder for locally retained installers and updater metadata.
Clarified that .env is developer/live-test scaffolding only; normal users configure API keys in Trebell Settings.

Retired obsolete mobile-device control and mobile-companion surfaces.
Moved runtime-specific behavior behind capability contracts where appropriate.
Kept managed-inference behavior provider-aware without coupling conversation identity to provider.
Made SQLite authoritative over the JSONL event mirror and fixed byte-bounded fallback compaction.
Added explicit verified/unverified trust labels to repository knowledge.
Added MCP result redaction regression coverage.
Fixed truthful runtime-readiness reporting in Settings.
Fixed exhausted thread-history pagination.
Hardened UI tests against asynchronous navigation/readiness races.
Made Playwright build the current UI automatically before local runs.

Rebuilt README.md around the current multi-harness product instead of the older Codex-only architecture.
Added MANUAL_TESTING.md with real-world validation steps for providers, runtimes, WSL/SSH, forges, MCP, packaging, updater, persistence, secrets and long-running workflows.
Tightened third-party attribution and provenance documentation.
