Closes DOCS-AUDIT §6.2.
Commander derives an option's destination from its long flag with `no-`
stripped, so `--no-history` wrote to the same `options.history` that
`-H, --history <id>` reads. `nopy install -H abc --no-history` set it to
`false`, the id was discarded without a word, and the run fell through to a
full interactive session instead of replaying anything.
The two cannot share a destination, so one spelling had to change, and it is
the boolean that moved: `-H <id>` is what the help text, the README and
`docs/API.md` all use, and "save history" is what the flag actually suppresses
— next to `-s, --save-session`. The old spelling now fails loudly instead of
silently.
Verified by running the CLI, since `nopy.cli.ts` is argv wiring and excluded
from coverage:
install --no-history -> error: unknown option '--no-history'
install -H nonexistent-id --no-save-history -> Session not found: nonexistent-id
The second line is the finding: the id used to be destroyed there.
