docs(readme): convert README.adoc -> Markdown (renders on Glama/profile/community-health) (#35)

README was AsciiDoc → renders as raw markup in Markdown consumers (Glama
MCP directory, GitHub community-health, GitHub profile). pandoc
asciidoc→GFM (badges → clickable), SPDX header kept, duplicate `.adoc`
removed. Part of the estate README-format fix.

+# What Is This?
+
+Anvomidaviser converts **ISU (International Skating Union) notation**
+into formal figure skating programs via **Anvomidav** — the first
+programming language for figure skating choreography.
+
+The pipeline: ISU notation → formal choreography models → scoring
+validation → program component analysis.
+
+Anvomidaviser bridges existing notation systems (ISU element codes, IJS
+protocols, Code of Points tables) to formally verified Anvomidav
+programs.
+
+# How It Works
+
+Describe your program in `anvomidaviser.toml` or import ISU protocols.
+Anvomidaviser:
+
+1.  **Parses** ISU element codes — jumps (`3Lz`, `4T+3T`), spins
+    (`CCoSp4`), steps (`StSq3`), lifts
+
+2.  **Validates** against ISU technical rules — Zayak rule, element
+    counts, well-balanced requirements
+
+3.  **Scores** using the Code of Points — base values, GOE adjustments,
+    PCS, deductions
+
+4.  **Generates** formal Anvomidav programs with timing, transitions,
+    and rink positions
+
+5.  **Outputs** score sheets, validation reports, and choreography files
+
+# Use Cases
+
+- **Competition program planning** — build programs, check legality,
+  estimate scores before training
+
+- **Judging consistency checks** — verify scores against ISU rules
+  programmatically
+
+- **Training feedback** — track element difficulty progression across
+  seasons
+
+- **Coaching tools** — visualise program layout, timing, and transitions
+
+# Architecture
+
+Follows the hyperpolymath -iser pattern:
+
+    anvomidaviser.toml (manifest)
+            |
+            v
+       ISU Parser (Rust CLI)
+            |
+            v
+       Idris2 ABI (proves scoring rule correctness)
+            |
+            v
+       Zig FFI (C-ABI bridge to scoring engine)
+            |
+            v
+       Anvomidav Codegen (formal program descriptions)
+
+Part of the [-iser family](https://github.com/hyperpolymath/iseriser).
+
+# CLI Commands
+
+```bash
+# Create a new manifest
+anvomidaviser init
+
+# Validate a manifest against ISU rules
+anvomidaviser validate -m anvomidaviser.toml
+
+# Generate Anvomidav program and score sheets
+anvomidaviser generate -m anvomidaviser.toml -o generated/
+
+# Build generated artifacts
+anvomidaviser build -m anvomidaviser.toml --release
+
+# Run the scoring engine
+anvomidaviser run -m anvomidaviser.toml
+
+# Show manifest information
+anvomidaviser info -m anvomidaviser.toml
+```
+
+# Example Manifest
+
+```toml
+[workload]
+name = "ladies-short-2026"
+discipline = "ladies-single"
+segment = "short-program"
+
+[elements]
+jump_1 = "3Lz+3T"
+spin_1 = "FCSp4"
+step_seq = "StSq4"
+jump_2 = "3F"
+spin_2 = "CCoSp4"
+jump_3 = "2A"
+spin_3 = "LSp4"
+
+[program]
+music = "Clair de Lune"
+duration_seconds = 160
+
+[output]
+format = "anvomidav"
+score_sheet = true
+validation_report = true
+```
+
+# Status
+
+**Pre-alpha / Codebase in progress.** Architecture defined, CLI
+scaffolded, bespoke Idris2 ABI types for ISU scoring, Zig FFI stubs with
+anvomidaviser symbols. Codegen and scoring engine pending.
