forked from unom/punktfunk
`punktfunk help` was one usage blob, and `punktfunk pair --help` was worse than nothing: the flag fell through to the verb, which read "--help" as its subject, printed a terse usage line to stderr and exited 5. For the command that is about to be the documented door for scripts and plugins (Playnite shells to `library --json`), "self-documenting" has to actually hold. Now `punktfunk help <command>` — and `--help`/`-h` after any verb, caught BEFORE dispatch so no verb can mistake the flag for its subject — prints that command's own page: flags, what lands on stdout vs stderr, and which exit code means what, which is the part a script author actually needs. Help goes to stdout and exits 0; an unknown topic refuses with 5. A unit test walks USAGE and asserts every advertised verb has a help page that leads with its own invocation, so the overview and the pages cannot drift apart, and an integration test runs the REAL binary over both spellings. `reachable` also stops scolding: probing an unsaved address is that verb's documented use, but it resolved through the saved-host path first, whose "pair it first" advice printed before the probe ran. It resolves quietly now — same lookup, no lecture. Verified on the Windows CI runner (clippy -D warnings, fmt, 8/8 tests, and the built punktfunk.exe by hand: overview, per-verb pages, quiet `reachable` exit 2) and in the Linux CI image (same gates, 8/8). One field note from the hand run: the exe needs the FFmpeg DLLs beside it or on PATH — true of the session binary already, and the MSIX ships them next to both, so packaging is unaffected.
