fix(cli): reject a --since date later than --until - #1733
Conversation
A reversed window loaded every entry, kept nothing, and printed an empty report with exit 0, which reads as "no usage data" rather than a typo. Both bounds are already normalized to YYYYMMDD, so the check is a string comparison that runs after config bounds and flags are merged, for every report command.

In `@docs/guide/cli-options.md`:
- Line 24: Update the date-window documentation around the `since` and `until`
validation statement to clarify that reversed bounds are rejected for report
commands, while `statusline` accepts reversed configured bounds because it
ignores report date filters.

Reviewed changes — validated the full diff for rejecting a reversed --since/--until window at parse time.
- Reversed-window rejection — new
date_window_errorin the CLI parser compares the normalizedYYYYMMDDbounds after flags and config are merged, so a--sincelater than--untilfails with a clear message and exit code 2 instead of an empty report. statuslineexemption — the check is skipped forstatusline, which ignores date bounds at runtime, so reversed configured defaults do not break it.- Exact regression coverage — five new parser tests pin the normalized error message for flag-only, mixed flag-plus-config, and config-file windows, plus equal-bounds acceptance and the
statuslineexemption. - Docs — one line in
guide/cli-options.mddocuments that the rejection applies to flags, config files, and mixed sources.
Verification performed: traced the --since/--until flow from parse_date_bound (flags) and apply_shared_options (config) through report_shared to the new check, confirming the plain string comparison is sound on normalized values; confirmed statusline never consumes date bounds (statusline_shared rebuilds from SharedArgs::default); confirmed --last interplay is safe since --last plus any bound is already rejected and last_window::resolve runs post-parse and cannot manufacture a reversed window; confirmed all Command variants remain exhaustively matched. Could not run cargo test in this environment (missing LiteLLM pricing snapshot, unrelated to this change), so relying on the reported cargo test -p ccusage-cli-parser, Clippy, fmt, and hawk runs.

Closes #1729.
This carries forward #1731 by @ravsau, preserving the original commit author, and adds the maintainer follow-up requested by review:
statuslineignores report date bounds, so reversed configured defaults must not make that command fail.The follow-up was developed test-first. The regression fails on the original PR head and passes after the parser skips date-window validation for
statusline.Validation:
