Simplify workspace package builds and deps

[juliusmarminge]

Summary

• Moves several @t3tools/* workspace packages from devDependencies to runtime dependencies where they are actually consumed.
• Removes redundant package versions and unused tsdown build scripts from internal packages that are no longer published independently.
• Simplifies tsdown externalization rules in apps/desktop and apps/server to match the new package layout.
• Drops the dedicated test:process-reaper script in apps/server and keeps the main Vitest entrypoint.
• Adds @effect/platform-node-shared to apps/server to support the updated server dependency graph.

Testing

• Not run (not provided in the commit diff).
• Expected verification: bun fmt
• Expected verification: bun lint
• Expected verification: bun typecheck
• Expected verification: bun run test

Note

Medium Risk
Medium risk because it changes package exports/bundling rules (notably @t3tools/contracts dropping CJS entrypoints) and shifts workspace dependencies, which can cause runtime/module-resolution issues in consumers.

Overview
Consolidates advertised-endpoint helpers into @t3tools/shared/advertisedEndpoint and updates desktop backend imports to use the new shared module, while keeping @t3tools/client-runtime as a thin re-export for compatibility.

Cleans up workspace packaging by moving @t3tools/* deps to runtime where used (e.g., desktop), removing per-package tsdown build scripts/metadata for internal-only packages, and simplifying bundler noExternal rules in both desktop and server.

Updates server deps/scripts by adding @effect/platform-node-shared and dropping the dedicated test:process-reaper script; @t3tools/contracts exports are simplified to ESM-only via the exports map.

Note

Move advertised endpoint utilities to @t3tools/shared and simplify workspace package builds

• Moves createAdvertisedEndpoint and related types from @t3tools/client-runtime into a new @t3tools/shared/advertisedEndpoint subpath export; client-runtime now re-exports from there.
• Updates imports in DesktopServerExposure.ts and tailscaleEndpointProvider.ts to use the new source.
• Removes standalone dev/build scripts and tsdown dependencies from contracts, effect-acp, and effect-codex-app-server packages, consolidating build responsibility into consuming apps.
• Removes CJS require export targets from packages/contracts, making it ESM-only.
• Behavioral Change: the desktop bundler no longer treats effect-acp as noExternal, and the server bundler adds effect-codex-app-server to its internal prefix list, changing what gets bundled vs. left external.

Approvability

Verdict: Approved

Mechanical refactoring that moves shared code from client-runtime to the shared package, updates import paths, and cleans up build configurations and dependency organization. No runtime behavior changes - the relocated code is identical to the original.
