v0.92.1 — std::format/print/println built in; binaries for Linux, Windows, macOS

madc v0.92.1

This is the download release for the v0.92 line — the first published
binaries on all three platforms since v0.82.0. Every feature below ships
in the attached packages (Linux .deb/.rpm, Windows zip, macOS
tarballs for Apple Silicon and Intel).

Features

• std::format, std::print, and std::println are simply part of
  madc — no includes, no header parsing:
  std::println("x={} y={:.3f}", x, y); works in a bare script. Literal
  format strings are validated at compile time (bad presentation types,
  bad indexes, and malformed strings are compile errors), and output is
  pinned byte-for-byte to real libstdc++ std::format by 1430 generated
  oracle rows — shortest-round-trip floats, bit-exact hex floats, the
  works. std::format returns a real std::string.
• cout << value with zero includes — value/var is an inherent
  madc type, and streaming one works in a bare script regardless of
  include order: var test = "hello"; cout << test << endl; — and it
  honors <iomanip> manipulators (setprecision, setw, setfill).
• UFCS in the madc dialect — free functions call as methods and
  methods as free functions under --std=madc.
• php::print_r / php::var_dump over ANY madc type — structs,
  classes, containers, nested aggregates, not just value/array;
  cycle-safe, with the type words a human expects (std::vector<int>,
  not the canonical four-argument spelling).
• Range-for over PHP arrays with the carrier as the element —
  for (value v : arr) is kind-preserving with copy semantics; auto
  elements work too.
• value maturity — value(N) constructors in temporaries,
  direct-init, and loop headers; .count()/.size() owner semantics;
  php::array_push as one overloaded name returning the new count.
• Headerless libc calls get real signatures — an undeclared
  floorf(3.9f) passes a genuine float (nine argument shapes, three
  suffixes each) instead of the variadic promotion garbage.
• --version reports the build.

Fixes and internals

• win64: ucrtbase hides four C99 float-math names (fabsf, frexpf,
  hypotf, ldexpf) from runtime lookup; they are now pinned in the
  name map, closing the complete hidden set (found by the new
  three-platform release gate).
• win64: var_dump(long) printed the rank's int(42); the LLP64
  platform long now words as its source name — long(42) on every
  target.
• Front end: a cast binds a paren-less sizeof/alignof operand
  ((long long)sizeof chunk).
• Numeric overload grading: a float argument selects double, never
  truncates.
• Process: every master promotion is three-platform and the platform
  suites gate it; fulltest gates the merge wave; master release notes
  summarize everything since the previous master release, features
  first.

Validation

Linux fulltest, native EXE/OBJ lanes, packed and headerless suites,
Windows wine packed suite, and the macOS release verifiers — all green
at this tag. Counts in docs/test-status.md and the
CHANGELOG.
