fabro-redact: add SecretRedactor for per-run exact-value redaction (#542)
Adds a `SecretRedactor` primitive to `fabro-redact` so that low-entropy
secret values (e.g. environment names, short tokens) are redacted even
when the existing content-based heuristics (`redact_string`,
`redact_json_value`) would leave them alone.

The type is a cheap, `Clone`-able handle backed by
`Arc<RwLock<Vec<String>>>`, so a clone handed to another subsystem
shares the same registry. `register` ignores empty/whitespace-only
values to prevent a footgun that would blank all output. `redact_into`
sorts and merges match regions before substituting, so a secret that is
a prefix of another longer secret is handled correctly (longest wins via
union). `redact_json` walks string leaves in objects and arrays; object
keys are left intact.

This is an inert library primitive — it changes no existing behavior and
is wired up by Plan C. The existing `"REDACTED"` literal is extracted to
a `pub(crate) REDACTION_MARKER` constant so both the old path and the
new one stay in sync.
