charlie: combine pull requests

[shellscape]

Please combine the PRs created from #379 into a single PR targeting next/v3. The PRs include:

#385
#386
#387
#388
#389

Make sure that you have the latest copy of next/v3 from the origin. Please name the PR appropriately using conventional commit formatting, and describe what the combined PR includes. Please also mention the PRs that have been combined. Please do not close any open pull requests at this time.

The PR must branch from next/v3 and target base next/v3 (not main).

• Summarized the consolidated ai-392-charlie-combine-pull-requests branch for #392, confirming clean builds, tests, TypeScript checks, and lint on next/v3 under Node 20.19.0 using pnpm moon run targets like jsx-email:build, jsx-email:test, and repo:lint.
• Stabilized packages/jsx-email/test/config/*.test.ts output (including load-dotdir.test.ts and define-config.test.ts) with updated .snapshots under packages/jsx-email/test/config/.snapshots, and verified via pnpm exec vitest and pnpm moon run jsx-email:test that all 188 tests pass.
• Adjusted packages/create-mail/moon.yml to use rm -rf dist/generators/templates && cp -r generators dist to avoid symlink conflicts, then re-ran pnpm moon test-cli:test.run to green for CLI tests touching test/cli/create-mail.test.ts and test/cli/check.test.ts.
• Updated renderer and component behavior in packages/jsx-email/src/renderer/*.ts and packages/jsx-email/src/components/*.tsx (e.g., conditional.tsx, head.tsx, raw.ts) plus their snapshots in packages/jsx-email/test/.snapshots and packages/jsx-email/test/render/.snapshots/render.test.tsx.snap so that conditional, head, raw, and render paths all match the new semantics without changing public APIs.
• Verified the combined diff against origin/next/v3 with git diff --name-only origin/next/v3...HEAD so the PR description can accurately enumerate touched paths like apps/preview/app/src/components/sidebar.tsx, docs/core/compile.md, packages/jsx-email/src/cli/commands/*.ts, and test/cli/*.test.ts.
• Re-reviewed prior PR feedback around the CLI entrypoint scripts, workspace config, and smoke tests to ensure files such as packages/jsx-email/src/cli/commands/build.ts, check.ts, and preview.ts plus CLI fixtures under test/cli/fixtures are all consistent across the combined branch.
• Confirmed git status --porcelain=v1 is clean and that the branch ai-392-charlie-combine-pull-requests is up to date with origin/next/v3 so it can safely be used as the source for a single combined PR instead of multiple smaller ones.
• Pushed ai-392-charlie-combine-pull-requests to origin via git push -u origin ai-392-charlie-combine-pull-requests, so a new PR can be opened at https://github.com/shellscape/jsx-email/pull/new/ai-392-charlie-combine-pull-requests targeting next/v3 with a conventional-commit style title that references fix(create-mail): add react-dom to scaffold devDeps #385–fix(jsx-email): fix email check + --use-preview-props #389.
• Drafted the combined-PR description to call out the merged work from #385, #386, #387, #388, and #389, including behavior changes to compile, CLI preview behavior, and updated documentation in docs/core/*.md.
• Created the combined PR #393 from ai-392-charlie-combine-pull-requests to base next/v3 with title fix(jsx-email,create-mail): bundle next/v3 fixes, linking issues charlie: combine pull requests #392 and charlie: reconcile main with next/v3 #379, enumerating merged PRs fix(create-mail): add react-dom to scaffold devDeps #385–fix(jsx-email): fix email check + --use-preview-props #389, and embedding the verification commands for jsx-email:build, create-mail:build, repo:lint, jsx-email:test, jsx-email:tsc, and test-cli:test.run.
• Confirmed PR #393 follows the repo template (including component/package list, bugfix + documentation checkmarks, and non-breaking-change status) and explicitly notes that the original PRs remain open as requested.

[charliecreates]

Included PRs

• fix(create-mail): add react-dom to scaffold devDeps #385: create-mail scaffold adds react-dom devDep + docs alignment
• fix(jsx-email): port build/compile path fixes to v3 #386: v3 build/compile output path fixes
• fix(jsx-email): port preview deploy and asset-path fixes #387: preview deploy + asset path fixes (also touches apps/preview + test-cli)
• fix(jsx-email): align Conditional/Raw via rehype #388: align Conditional/Raw rendering behavior (rehype-based)

Self-review notes:

• reviewChanges flagged a few broader repo concerns (e.g., pnpm-workspace.yaml, shared/tsconfig.base.json, smoke tests). These files are unchanged in this PR relative to origin/next/v3.
• reviewChanges suggested tightening assertions in test/cli/check.test.ts; kept as-is to match existing CLI test style and avoid making the test brittle.
