chore: sync with upstream pingdotgg/t3code main

[yordis]

• Upstream now records provider turn and session metrics in ProviderSessionManager, so the fork's duplicate recording in RunExecutionService and ProviderTurnControlService was removed to avoid double counting; the fork-only orchestration and runtime event metrics stay because upstream has no equivalent.
• Relay tracing takes upstream's layer names and serialization layer while keeping the fork's process resource attributes and service instance id, so traces stay attributable per process.
• The relay Worker now owns trace export upstream, so the fork's isolate-scoped trace layer there was dropped in favor of upstream's observability module.
• Stopping a run whose provider session died now follows upstream's interrupt semantics, since upstream covers what the fork's process loss reconciliation did; the fork keeps only cancelling effects bound to the dead session, which upstream does not do.
• Runtime recovery keeps the fork's extracted thread reconciliation planner and gains upstream's secret request cancellation, so neither side's recovery behavior is lost.
• Pull request merges keep the fork's explicit opt-in for bypassing branch rules alongside upstream's agent credit removal setting, since both guard different merge concerns.
• Provider registry, secret resolution, and Claude credential divergences were carried onto upstream's flat provider layout so per-environment instances and 1Password-backed secrets keep working.
• RPC spans join the client's trace again after upstream's RPC module move broke the fork's propagation.
• Fork-only code and tests were adapted to upstream's renamed layers and module paths, and the lockfile keeps the fork's @legendapp/list patch hash because that patch still diverges.

PR Summary

Medium Risk
CI and relay deploy defaults affect every PR and production relay rollouts; the large vendored reference sync is read-only but increases review noise and could mask accidental edits under .repos/.

Overview
Replaces CodeRabbit’s YAML config with a TypeScript config that keeps auto-review and .repos/** exclusions, turns off docstring pre-merge checks, and wires path-specific review instructions plus a knowledge base to docs/internals/effect-services.md and docs/internals/web-ui.md.

CI and release pipelines install Playwright Chromium (shell only) before server tests, move the transfer-report job to Blacksmith with a short timeout, and for nightly Discord prerelease posts fetch the published GitHub release body and pass it to notify-discord-release.ts.

Relay deploy workflow documents that force redeploy is rarely needed (Postgres role replacement risk), sets workflow_dispatch force default to false, and passes RELAY_LEGACY_TUNNEL_CLEANUP_MODE into the deploy job.

Smaller repo hygiene: vouch github:esthor, fix the flaky-test path for ProviderRegistry.test.ts in Cursor cloud docs.

The bulk of the diff refreshes the read-only .repos/alchemy-effect reference checkout—Effect 4 import path migrations (effect/http/*, effect/ai, etc.), Alchemy v2.0.0-beta.80 changelog, CI/pack workflow hardening, and many new or expanded examples (AWS Aurora/DSQL Drizzle, Cloudflare Better Auth, Durable Object SQL, vinext on AWS, Prisma PSL, and related docs/tests).

📝 Walkthrough

Walkthrough

This pull request updates CodeRabbit configuration, CI and release workflows, relay deployment inputs, a Cursor rule path, and the repository trust list.

Changes

CodeRabbit review configuration

Layer / File(s)	Summary
Review settings and path guidance .coderabbit.config.ts, .coderabbit.yaml	CodeRabbit settings move from YAML to TypeScript. The configuration adds path-specific instructions and matching knowledge-base patterns. It excludes .repos/** from reviews.

CI and release workflows

Layer / File(s)	Summary
Server test browser setup .github/workflows/ci.yml, .github/workflows/release.yml	The server test jobs install Chromium’s headless shell and its system dependencies before running tests.
Transfer report runner .github/workflows/ci.yml	The transfer-report job uses blacksmith-2vcpu-ubuntu-2404. Its five-minute timeout is unchanged.
Prerelease release notes .github/workflows/release.yml	The workflow prepares a release-notes file for prerelease Discord notifications. Nightly releases use the published release body when readable; other prereleases and read failures use an empty file.

Relay deployment workflow

Layer / File(s)	Summary
Relay deployment inputs .github/workflows/deploy-relay.yml	The manual force input now defaults to false, and its description covers resource redeployment and Postgres runtime role replacement. The deploy job receives RELAY_LEGACY_TUNNEL_CLEANUP_MODE from a repository variable.

Cursor guidance path

Layer / File(s)	Summary
Flaky-test path .cursor/rules/cursor-cloud.mdc	The flaky-test entry now points to apps/server/src/provider/ProviderRegistry.test.ts.

Repository trust list

Layer / File(s)	Summary
Trust list entry .github/VOUCHED.td	The trust list adds github:esthor.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes
