Unify package version on VERSION file; bump abc2midi to 5.03 (#25)

- abc2midi 5.03 (April 2026): bumped #define VERSION in store.c to reflect this branch's accumulated fixes
(error exit status, missing C:/R:/X: header emission, %%MIDIdef macros allowed anywhere) plus the
build-system additions.
- Single source of truth for the package release date: the VERSION file is now consumed by both build
paths.
  - CMakeLists.txt reads it via file(STRINGS VERSION ABCMIDI_VERSION ...); the previously hard-coded
project(VERSION 2026.02.24) (an unused PROJECT_VERSION) is dropped because the date format isn't
MAJOR.MINOR.PATCH.
  - configure.ac uses m4_esyscmd_s([cat VERSION]) in AC_INIT, replacing the very stale hard-coded
2011-08-03.
  - The two build paths remain independent — no cross-generation between CMake and autoconf.
- Test normalization fix (tests/run_test.cmake): the version-banner regex now requires a capitalized month
and accepts a date with or without a day number. The previous regex was lowercase-permissive and silently
ate PostScript lines like 0.5 setlinewidth 0 0 moveto in yaps output — tests/golden/yaps_coleraine.txt is
regenerated to reflect the now-correctly-preserved PostScript.
- Docs:
  - doc/CHANGES: April 25 2026 entry covering the version bump and VERSION-file unification.
  - doc/readme.txt: per-tool listing updated (abc2midi 5.03 April 2026, midistats 1.03 February 20 2026
synced to source).
  - doc/abc2midi.1: header label bumped to 5.03 April 2026 (content not audited).
  - README.md: new Maintainers / releasing section documenting the release procedure, including the
requirement to run autoreconf -f so the committed configure picks up the new AC_INIT arguments.

+### Maintainers / releasing
+
+The package release date in the `VERSION` file is the single source of
+truth for the package version. It is read by `CMakeLists.txt` (into
+`ABCMIDI_VERSION`) and spliced into `configure.ac`'s `AC_INIT` via
+`m4_esyscmd_s` at autoreconf time. Each individual program also keeps its
+own `#define VERSION "<n.nn> <date> <toolname>"` in its `.c` file
+(e.g. `store.c` for `abc2midi`); these are bumped per-tool when that
+tool's behaviour changes.
+
+To cut a release:
+
+1. Update the `VERSION` file (e.g. `April 25 2026`).
+2. For each tool whose behaviour changed since the last release, bump
+   its `#define VERSION` string in the corresponding source file.
+3. Run `autoreconf -f` so the committed `configure` picks up the new
+   `AC_INIT` arguments. The CMake build does not need this step — it
+   reads `VERSION` directly at configure time.
+4. Run `ctest --preset debug` and, if a golden-file test fails because
+   of an intentional output change, regenerate with
+   `cmake --build build/debug --target update-golden` and review the
+   diff.
+5. Append an entry to `doc/CHANGES` and update the per-tool version
+   listing at the top of `doc/readme.txt`.
+6. Commit and tag.
