v0.1.0

Added

• Symbol-first scientific computing toolchain: hand-written lexer, recursive-descent/Pratt parser, AST and diagnostics (prima-syntax).
• Numeric tower Integer < Rational < Complex<Rational> < F64 < Complex<F64> with hash-consing expression pool (prima-core).
• Symbolic engine: MFn evaluation, implicit broadcasting, TeX literals, simplification levels 0–3.
• Phase 2 runtime: config policy system (fraction/domain/broadcast/undefined_handling), collapse function families, if/while/for/return control flow, classes, module system, prima check static analysis.
• v2.1 collection types: mutable Array, Dict/Set, comprehensions and convenience functions.
• Standard library as embedded .pra signature modules bound to @builtin implementations (linalg/stats/io/physics/plot/sys/time/num).
• CLI subcommands: run, check, repl, fmt, test, doc, compile --emit-headers.
• Rustc-style colored diagnostics via codespan-reporting.
• MIT license and a release workflow building all Rust Tier-1 platforms with SHA-256 checksums.
