1.0.0

CHANGES:

First release — an OCaml port of the self-contained Rust mermaid.rs terminal
renderer from xai-org/grok-build
(Apache-2.0; see NOTICE).

• Render five Mermaid diagram types to Unicode box-drawing art — flowchart /
  graph, state, class, entity-relationship, and sequence — including subgraphs,
  self-loops, thick/dotted edges, arrowhead variants, and diagram-specific
  features (choice pseudo-states, class members/annotations/generics, ER
  cardinalities, sequence notes/blocks/autonumber). Unrecognized or too-wide
  input renders as a framed fallback box.
• Public API: Termaid.render : ?max_width:int -> string -> t option, returning
  plain UTF-8 lines plus a TUI-agnostic, class-tagged span model (map the cls
  of each run to your own colors). No terminal-framework dependency; Unicode
  width via uucp/uutf.
• Layout engine: Sugiyama-style rank assignment, barycenter crossing reduction,
  coordinate relaxation, and greedy track packing, painted onto a box-drawing
  canvas with junction-aware glyph resolution.
• Verified byte-for-byte against the upstream renderer across 53 golden fixtures
  (every diagram type plus wide/tall/dense layout stress cases); 145 invariant
  tests faithfully port the upstream test suite. CI covers Linux and macOS on
  OCaml 4.14 and 5.
