Kang 105869adc4 refactor(core): split command history and known hosts out of storage.rs ...

`storage.rs` was 7662 lines with one `impl ConnectionStore` spanning
three thousand of them. Earlier rounds extracted a few pure type modules,
which barely moved the count because the types were the small part.

These two go out as whole domains instead, each taking everything that
belongs to it: table constants and key prefixes, record types, the
`*_in_txn` helpers, and — for command history — the prompt-stripping
logic that only `sanitize_history_command` used.

`known_hosts` also took `storage.rs`'s only uses of `base64`, `hmac` and
`sha1`. Three crate dependencies leaving with one domain is the sign the
seam was in the right place; a type-by-type extraction would never have
surfaced that.

Table names, key layouts, record shapes, the legacy text-doc import and
the hashed-host matching rules are unchanged — this moves code, it does
not touch the persistence contract. 166 core tests still pass, including
the known-hosts structured/hashed/raw round-trip, the match/changed/
unknown distinction, the legacy import, and command-history
normalization.

storage.rs: 7662 -> 7077 lines.
