v1.0.0

• A static Zig build of every command, one binary per architecture
  (x86_64, aarch64) built for linux-musl on zig-common 0.8.0: probe,
  status, resolve, retire, gc, run, resume and rollback, with
  and without --ledger-config, plus ledger-maintenance and
  build-events as subcommands. Its output matches the Python tool byte for
  byte except where COMPAT.md lists a deliberate difference. Releases carry
  the binaries, SHA256SUMS and build provenance attestations.
• CI checks both builds against each other. A differential runs every
  command and compares the trees and journals it leaves. A crash matrix kills
  a run, a rollback and a retire at every fault step (295 cases). A fail
  matrix gives every step an I/O error (152 cases). The signal, ledger,
  metadata, access-control, build-events and real-EasyBuild suites also run
  against the binary. TESTMAP.md maps each test that imports the Python
  code to what covers it for the binary, and CI fails on a missing row.
• Fix: a run killed right after RENAME_EXCHANGE resumes to the published
  state, and a rollback killed right after its exchange rolls back once.
• Fix (binary): an allocation failure stops the program. It never runs
  eb with the parent environment and without the staged install paths.
  A restore that cannot be recorded is not ignored. A damaged build-events
  state file is refused instead of crashing. Error text names the errno the
  kernel gave.
• Fix (binary): a missing eb-stack is "cannot start", as in Python, and a
  stop during ledger delivery kills the ledger's process group first.
• The ledger call keeps the first 64 KiB of each stream, returns when
  eb-stack exits and stops any process it left behind.

  release-binary install and the Zig build's differences.
