Upgrade: Anthropic.ts report exists only on stdout while state is saved, and --help runs a full scan #2290

Version

LifeOS 7.40.4. Same code on main today (Tools/Anthropic.ts, 1021 lines).

What is broken

Anthropic.ts prints its report only to stdout and saves State/last-check.json at the end of every successful run. So the report exists exactly once. If the output gets cut (an agent piping it through tail, a terminal scrollback limit, a tool-output size cap), the delta is gone, and a second run reports nothing because the state has already moved on.

The argument parser makes this easy to hit. It reads the first non--- argument as the day count and checks only for --force. Any other flag, --help included, is ignored and a full scan runs, which saves the state.

We lost the delta this way on two runs in a row and had to rebuild it from the previous state file in git.

Where (file:line)

• LifeOS/install/skills/Upgrade/Tools/Anthropic.ts:94-97 (argv: day count and --force only)
• LifeOS/install/skills/Upgrade/Tools/Anthropic.ts:1011 (saveState after the report is printed to stdout)

Suggested fix

1. Write every report to a file as well, for example Logs/report-<timestamp>.md, and print its path at the end. The run history in Logs/run-history.jsonl already records counts, so the report next to it fits.
2. Make --help print usage and exit without fetching or saving state. Reject unknown flags the same way.

Optional: a --no-save flag for a dry run that leaves the state untouched.

This overlaps with the rewrite announced in #2227 (pagination and the import.meta.main guard), so it may be easiest to fold in there.
