v0.15.1

Install or upgrade:

curl -fsSL https://x2c-lang.dev/install.sh | sh

A patch release of 0.15.0. Existing installations upgrade in place; no
packages need rebuilding.

• An uncaught error prints one line naming the error, the raising function
  and location, and its details, then aborts with the same status. The
  full logger event remains available with X2C_DEBUG or a <log> policy.
  See Handlers and policy.
• $auto on a local that is already managed is a compile-time error
  instead of a crash at scope exit.
• The REPL continues a list literal across lines, and code it loads
  boxes classes, expands its own meta functions, and calls protocol
  defaults as an ordinary build does.
• REPL input and compiled prompt functions can call C's printf and
  puts. See the REPL guide.
• The book gains this release notes page, and the repository gains a
  security policy, a pull request template, and a bug report template.
