v0.77.5

[0.77.5] - 2026-05-06

Fixed

• Sweep of script/*.rhai: every script in the gallery now runs
  without Rhai static-shape errors. Three classes of bug were fixed
  across 12 scripts:
  • for (val, key) in <map> destructuring iteration (left over
    from an older Rhai version) failed with "For loop expects iterable
    type" in email.rhai and ldap.rhai. Rewrote to walk
    map.keys() and index for the value.
  • Chained mutating string methods — String::replace and
    String::trim are non-pure in this Rhai build (they mutate in
    place and return ()), so chains like
    url.replace("ftp://", "").replace("ftps://", "").split("/").shift()
    blew up on the second call. Replaced the host-port extraction
    in ftp.rhai, gopher.rhai, imap.rhai, pop3.rhai,
    smtp.rhai, sftp.rhai, tftp.rhai, and clipboard.rhai
    with a sub_string + index_of based extraction that doesn't
    rely on chaining.
  • Map .contains_key() not registered — used the in
    operator instead in email.rhai and checkdigit.rhai.
  • Array .join() not registered in this Rhai build — replaced
    with manual string concatenation in imap.rhai.
• Demo robustness: client-cert.rhai now exits cleanly with a hint
  when the cert path doesn't exist instead of erroring out;
  time-cond.rhai only attempts the second (etag-compare) fetch
  when the cache file actually exists; tcp-echo.rhai exits 2
  cleanly when the listen port is already in use; udp-listen.rhai
  treats EAGAIN ("Resource temporarily unavailable") the same way
  it already treats timeouts; impersonate.rhai wraps the
  feature-gated call in a try/catch so the default rustls build
  exits 2 with a rebuild hint instead of throwing.
