Browse's row context menu and in-place editors now consult the
server-computed verbs string (via window.zddc.cap.has) before
enabling write/delete affordances:
- Rename… disables when the entry's verbs lacks 'w'.
- Delete… disables when verbs lacks 'd'.
- Markdown editor mounts read-only when verbs lacks 'w'.
- YAML editor mounts read-only when verbs lacks 'w' for regular
files, 'a' for the .zddc placeholder (matches the file API's
ActionAdmin gate at that URL).
Disabled menu items carry a tooltip naming the missing access
("You don't have write access to this item.") so the user discovers
which permission is missing rather than just seeing a greyed row.
shared/context-menu.js gains a `tooltip` field (string or fn(ctx))
that sets the row's title attribute.
canMutate() stays as the source-side gate (server vs FS-API
reachability, zip-member / virtual filtering); verbs gate composes
on top. Server-side ACL still has the final say if a stale client
ever tries the action.
cap.has() falls back to node.writable for 'w' when verbs is absent,
so offline FS-API mode keeps working without a server.
