docs: OOP compiler + VM core design spec (milestone 1)
docs/superpowers/specs/2026-08-01-oop-compiler-vm-design.md (new): approved brainstorming design for the OOP-writeonce track's first sub-project — `woc` (OCaml, stdlib-only, handwritten lexer/recursive-descent parser) compiling `.wo` classes to register bytecode, and `wovm` (C, libc-only) interpreting it. Decisions locked: evolve wo-rt-c into the C runtime (Rust rt stays until parity); plan-13 doctrine kept (no inheritance — structural Go-style interfaces + composition); hybrid borrow enforcement (mutable value semantics, second-class borrows — compiler elides provable sites, VM checks residual sites via header borrow word); per-class @gc opt-out with RC + budgeted per-shard Bacon–Rajan cycle scan (no stop-the-world by construction); shard-actor concurrency reserved (header carries shard id, implementation is sub-project 2); root-level monorepo dirs compiler/ + runtime/ (nothing new under prototypes/). Spec covers .wob module format, ~40-op instruction set, trap/unwind error model with drop maps, conformance-corpus test strategy (run/must-fail-compile/must-trap), and measurable success criteria (<100 ms compile, ASan/Valgrind-clean suite, single-binary build).
