docs(readme): convert README.adoc -> Markdown README.md (#15)

README must be real Markdown to render in GitHub community-health, the GitHub
profile, and external MCP directories (Glama) — AsciiDoc shows as raw markup
there. pandoc asciidoc->GFM, badges fixed to clickable, SPDX header kept as an
HTML comment, duplicate README.adoc removed.

+
+A collection of satirical, parody, and comedic software projects.
+Security theater, absurdist tooling, and deliberately bad
+implementations — all engineered to a suspiciously high standard.
+
+# Projects
+
+| Project | Description |
+|----|----|
+| [befunge93-vault-cracker](befunge93-vault-cracker) | Satirical UI demonstrating esoteric programming absurdity vs. overengineered security theater. Uses Befunge-93 to "attack" an imaginary cryptographic vault. |
+| [blue-screen-of-app](blue-screen-of-app) | Humorous web app displaying authentic Blue Screen of Death errors across four Windows generations (XP, 7, 10, 11). Built with Deno and ReScript. |
+| [dicti0nary-attack](dicti0nary-attack) | Security research parody utility for generating and testing non-dictionary passwords. Demonstrates that creative misspellings are not security. |
+| [safe-brute-force](safe-brute-force) | Controlled, ethical brute-force utility with automatic safety pauses every 25 attempts. An OTP gen_statem state machine written in LFE. |
+
+# Purpose
+
+These projects exist to:
+
+- Illustrate security anti-patterns through deliberate absurdity
+
+- Explore esoteric and unusual programming paradigms
+
+- Demonstrate that humor and rigorous engineering are not mutually
+  exclusive
+
+All projects are fully implemented to Rhodium Standard Repository (RSR)
+quality standards despite their comedic subject matter.
+
+# Development
+
+Each sub-project is an independent git submodule with its own build
+system, tests, and CI workflows. See the individual project READMEs for
+build instructions.
