Release 1.4.0: shared @simpleworkjs/* packages; fix discovery envelope drift + client_secret_hash leak

Rewire onto @simpleworkjs/directory-schema, /ldap, and /app-stack. The
directory discovery API now returns the {results} envelope via explicit
/resources, /resources/:slug, /graph, /me handlers and routes every read
through projectResource/projectResources, which unconditionally strips
client_secret_hash (and any /secret|password|privatekey/i key) and reduces
metadata to a public allowlist for non-admins — closing the leak where the ORM
serialized metadata wholesale. The dead routes/api_discovery.js (mounted after
the 404 catcher) is removed; ?group= now returns 200 instead of 404. user_ldap
+ group_ldap take escapeFilter/escapeDN + makeClient/withClient from the shared
ldap package (posix/write-side stays app-local; cert validation unchanged).
build_info unified to {buildVersion,buildHash,buildYear}; ldapts ^8.1.8. New
tests/discovery.test.js locks in the envelope + no-secrets guarantees. Lockfile
regenerated from the registry (no file:/link:).
