Split the extractable parts out of the mail store
store/mail.ts was 1,463 lines. It is now a directory, so `@/store/mail`
resolves to index.ts and none of the 36 modules importing `useMail`
changes a line:
mail/props.ts 72 MAILBOX_PROPS, LIST_PROPS, FULL_PROPS, BODY_PROPS
mail/types.ts 125 ListQuery, ListState, MailState, DEFAULT_SORT
mail/mailboxes.ts 28 mailboxIcon, ROLE_ORDER
mail/index.ts 1,266 the store, and everything bound to it
Everything exported before is still exported from index.ts, so this is
file layout and nothing else. No behavior change, no call-site change.
WHAT THIS DOES NOT DO, and why. index.ts is still 1,266 lines because
947 of them are one `create<MailState>((set, get) => ({ ... }))`. Cutting
that up means Zustand slices -- splitting the state object itself and
recombining it -- which is a change to how the store is built rather than
to where its text lives, in the part of the app that every screen leans
on. That deserves its own PR and its own argument, not a quiet ride along
with a file move.
Three things had to stay behind and are worth knowing about, because the
obvious boundary is wrong in each case:
- `listKey` sits among the type declarations but is a function the
store calls, not a type.
- `ensureFolderPath`, `folderRefs` and `followFolders` read like folder
helpers and look like they belong beside mailboxIcon, but they close
over `useMail`. Moving them makes mailboxes.ts import index.ts, which
imports mailboxes.ts.
- the sieve import inside index.ts is `await import(...)`, not a static
one, so rewriting import paths by their `from` clause misses it.
