Problem

Closes #730 (reported by @AndDeluiz). When settings.render_command.dont_generate_typst is True and PDF/PNG generation is enabled, generate_pdf/generate_png silently skip compilation instead of producing output. The Typst source is required to compile the PDF/PNG, but the code path that should provide it when the standalone .typ file isn't being persisted was never wired up.

As @sinaatalay noted on the issue, the right fix is to generate the Typst source into a temporary location whenever it's needed for compilation, regardless of whether the user wants the standalone file kept around.

Fix

ensure_typst_source_for_compilation is now a @contextlib.contextmanager backed by tempfile.TemporaryDirectory(). generate_pdf/generate_png use it with a with block, so the temporary Typst source directory is created, used for compilation, and removed within the scope of that single compile call — on both success and error — rather than relying on a longer-lived temp dir.

This directly addresses the concern @sinaatalay raised on #577 ("Are we sure those temp dirs get removed at the end of the run?"), which along with the related #605 was closed over uncertainty about whether mkdtemp + atexit-based cleanup actually ran. Scoping cleanup to a context manager means it happens deterministically at the end of the with block, not deferred to process exit.

Also corrected the dont_generate_typst field description and CLI help text, which described it as controlling whether Typst (and therefore PDF/PNG) generation happens at all — it only controls whether the standalone .typ file is persisted to disk. Regenerated schema.json via just update-schema to match.

Changes

• src/rendercv/renderer/pdf_png.py: ensure_typst_source_for_compilation converted to a context manager over a TemporaryDirectory; generate_pdf/generate_png updated to use it via with.
• src/rendercv/schema/models/settings/render_command.py and src/rendercv/cli/render_command/render_command.py: corrected dont_generate_typst description/help text.
• schema.json: regenerated from the corrected model.
• tests/renderer/test_pdf_png.py: added coverage for temp dir cleanup on both success and error, confirmed a persisted typst_path is left untouched, and an end-to-end check that generate_pdf leaves no temp dir behind.

Verification

• uv sync --frozen --all-extras — installs cleanly (submodules, including typst_fontawesome, need git submodule update --init --recursive first).
• uv run --frozen --all-extras pytest tests/renderer/test_pdf_png.py tests/cli/render_command/test_render_command.py — 56 passed, 0 failed.
• uv run --frozen --all-extras ruff check on all files touched by this patch — all checks passed.
