refactor(trpc): migrate declaration emit to tsgo and stop committing dist

[jeanduplessis]

Summary

• Migrate the @kilocode/trpc declaration emit from tsc to tsgo for faster builds
• Stop committing the ~16k-line generated dist/index.d.ts to avoid painful rebase conflicts whenever router types change on main; the full packages/trpc/dist/ directory is now gitignored
• Extract the prepare lifecycle hook into scripts/prepare.sh so trpc types are auto-rebuilt after pnpm install; the script skips both husky and the trpc build in CI since they are unnecessary there
• Add a trpc build step to the CI lint job so type-aware oxlint rules have the declaration types available
• Fix pre-existing workspace test failures that were exposed by the packages/trpc changes triggering shared_changed in changed-workspaces.sh

Key changes:

• packages/trpc/tsconfig.json: added explicit rootDir for tsgo 7.0 compatibility
• packages/trpc/rollup.config.mjs: updated alias resolver with resolveDts() helper to handle tsgo's directory-style index.d.ts output (vs tsc's flat .d.ts files)
• scripts/prepare.sh: new file with set -euo pipefail for robust error handling, CI skip via $CI env var
• .github/workflows/ci.yml: added pnpm --filter @kilocode/trpc run build step before lint
• scripts/changed-workspaces.sh: skip workspaces that have a test script but no actual test files
• cloudflare-o11y/test/index.spec.ts: added created_at: expect.any(Number) to pipeline assertions
• cloudflare-ai-attribution/jest.config.mjs: added missing jest config with ts-jest transform

Verification

• pnpm install — prepare hook runs successfully, trpc types rebuilt
• pnpm typecheck — passes (tsgo --noEmit)
• pre-push hook (lint + typecheck) — passes
• pnpm --filter cloudflare-o11y test — 61 tests pass
• pnpm --filter cloudflare-ai-attribution test — 22 tests pass
• Verified changed-workspaces.sh no longer includes cloudflare-images-mcp or cloudflare-db-proxy (no test files)

Reviewer Notes

• The resolveDts() helper in rollup.config.mjs is needed because tsgo preserves path aliases differently from tsc — it may emit foo/index.d.ts instead of foo.d.ts. The helper tries both forms.
• The ${CI:-} syntax in prepare.sh is required because set -u treats unset variables as errors; $CI is unset in local dev environments.
• The 4 workspace test failures were pre-existing on main but hidden because the workspace-tests CI matrix was always empty on main pushes (no changed workspaces). This branch triggered shared_changed=true (via packages/trpc/**), which runs all workspaces with a test script.

WARNING: This pipeline can terminate the script as soon as a workspace has multiple tests

Because the script runs under set -euo pipefail, find ... | head -1 returns a non-zero status when head closes the pipe after the first match. Packages like cloud-agent and kiloclaw already have multiple matching test files, so the matrix generation can exit here instead of returning JSON. Use find ... -print -quit (or add || true) to probe for one match without tripping pipefail.
