v1.0.21 — bridge fixes + perseus knows

Fixed

• Legacy mneme:/mimir: config no longer shadowed by the default perseus_vault: block (#704) — the silent "Vault unreachable → local results only" regression for everyone who followed the recommended mimir: → mneme: migration. Legacy blocks fold into the canonical key at load (user values win); new perseus doctor check errors on a shadowed block.
• MnemeConnector.recall sends canonical Vault tool args (#699) — max_results never reached limit (every bridge recall was pinned to 10) and min_decay_score never applied.
• Serve index version badge follows the real package version (#696).

Added

• perseus knows (#692, alias perseus memory review) — plain-language "what does my assistant know about me?" with active-only counts, trust markers, short ids, and curation (--show / --forget / --correct, confirm-before-write).
• /knows serve endpoint + index panel (#695) — the same view over HTTP (markdown or ?format=json) through the redact + bearer-auth path; index gains active-only Vault stat cards.
