fix(scanners): close the CLI argument class across all fourteen CLIs

Browse source 
`KNOWN_OPEN` in cli-unknown-flag-rejection.test.mjs named two CLIs as still
carrying the argument-swallow defect. That number was the previous session's
field of view, not a measurement. Measuring all fourteen found **7** open on
the unknown-flag arm and **10** on a second arm the deferral note never
described.

Arm 1 — unknown flag: with no `else` branch, `--zzz` leaves no trace. exit 0,
full payload, a confident answer to a question the caller did not ask.

Arm 2 — the sharper one: `a === '--output-file' && args[i + 1]` asks only
whether a next token EXISTS, never whether it is a value. `manifest`,
`campaign-cli` and `knowledge-refresh-cli` each wrote a file literally named
`--json` into the caller's working directory when handed `--output-file
--json`, exit 0, with `--json` mode silently dropped. A wrong answer is bad;
an unintended file on disk is worse.

Two of the CLIs this catches were already in GUARDED and green on arm 1 while
arm 2 stood open a few lines away — the guard asserted one relation instead of
the invariant.

Fixed with a shared gate (`lib/cli-args.mjs`) that runs BEFORE each CLI's own
parse loop rather than replacing it: valid argv reaches the existing parser
byte-for-byte unchanged, so the byte-stability argument is structural rather
than empirical. `drift-cli`, `fix-cli` and `plugin-health-scanner` were
already correct on both arms and were moved into GUARDED instead of rewritten.
The three CLIs with a bespoke unknown-flag branch had it removed once the gate
made it unreachable.

Suite 1488 → 1531. Frozen v5.0.0 snapshots untouched; `self-audit
--check-readme` passed.
