Adds stdlib/encoding.affine — to_hex / from_hex / to_hex_padded / hex_digit / hex_value: lowercase, non-negative, 32-bit hexadecimal conversion built on the string-primitive layer (len / string_sub / string_find / ++) plus integer bit-ops. Integer / is deliberately avoided — it lowers to floating-point division on the Deno-ESM backend, so nibble math uses & and >> instead. Verified locally with a bootstrapped toolchain: the codegen-deno runner compiles tests/codegen-deno/encoding_smoke.affine under --deno-esm and the harness round-trips under Node; full suite green, no regressions. Base64 (the other half of stdlib #25) is deferred pending a Bytes type (#30). Bumps the #25 roadmap row to partial.

…verage Adds RFC 4648 base64 to stdlib/encoding.affine: to_base64 / to_base64_url / from_base64 / from_base64_url, byte-oriented via the string_char_code_at / string_from_char_code primitives. As in the hex half, group/remainder math uses bit-ops (no integer / — it lowers to float division on Deno-ESM, see #478). Verified: tests/codegen-deno/encoding_smoke compiles under --deno-esm and the harness round-trips the RFC 4648 §10 vectors under Node; full suite green.

…itives Adds two byte-oriented String<->Int builtins underpinning the base64 codec in stdlib/encoding.affine (#25). Wired across all four layers, consistently: - resolve.ml seed_builtins (name resolution) - typecheck.ml register_builtins: String->Int->Int / Int->String - interp.ml runtime impls (out-of-bounds read -> -1; from masks &0xff) - codegen_deno.ml __as_strCharCodeAt / __as_strFromCharCode + builtin map Unlike string_get/int_to_char (Char-typed, ASCII-clamped on the interpreter), these go String<->Int directly so a byte 0..255 round-trips identically on the interpreter and Deno-ESM backends. This is the compiler support the base64 half of the prior commit depends on. Verified: dune build green; tests/codegen-deno/encoding_smoke round-trips the RFC 4648 vectors under Node; full codegen-deno suite green.

The .as extension conflicts with ActionScript in GitHub Linguist, causing all AffineScript source files to be misclassified as ActionScript/JavaScript. This migration to .affine resolves the conflict and enables proper language detection.
