Problem

base64.lua uses openssl via io.popen and writes a temp file for
every encode/decode call. Base64 is a pure algorithm -- no external
dependency, no filesystem access needed.

Fix

Replace with a pure Lua implementation (~30 lines).
Removes: openssl dependency, io.open, io.popen, os.time temp files.

Also:

assert() must be replaced with nil, err (DAW standard)
Header path outdated: src/daw/lua/common/base64.lua

Impact

Faster, no dependencies, works without openssl installed.

b64url_encode/b64url_decode reimplemented on top of the pure-Lua b64_encode/b64_decode (issue #35) -- openssl dependency removed entirely. Verified byte-identical output against openssl base64 across ASCII, empty string, whitespace, and multi-byte UTF-8 samples. base64.lua is now genuinely zero-dependency, matching the README claim.
