v0.4.1

Patch release focused on vault-local config and better non-interactive behavior.

Highlights

• Add .carddown/config.toml support for persistent defaults.
• Merge config with precedence: CLI > config > built-in defaults.
• Support [storage].state_dir to keep SQLite DB, WAL/SHM, and lock files outside the vault.
• Preserve legacy JSON auto-migration from vault-local .carddown/ into the resolved state path.
• Improve integration coverage for config merge, external state dir, and non-TTY paths.
• Restore visible default values in CLI help for config-backed flags.
• Make audit a clean no-op when there are no orphaned or leech cards, even in non-TTY runs.

Example config

[storage]
state_dir = "../carddown-state"

[scan]
file_types = ["md", "txt", "org"]

[revise]
maximum_cards_per_session = 30
maximum_duration_of_session = 20
leech_failure_threshold = 15
leech_method = "skip"
algorithm = "sm5"
reverse_probability = 0.0

Upgrade notes

• No breaking changes.
• Existing vaults continue to work without config.
• If state_dir is set, new SQLite state is written there while config and legacy JSON migration source remain under .carddown/.
