release: 1.0.2

[davydog187]

Prepares the 1.0.2 release: bumps @version in mix.exs and adds the CHANGELOG entry for everything merged since v1.0.1.

Patch bump — all fixes and internal performance work, no public API change.

Changed

• Lua.new/1 ~100x faster via a memoized boot-time VM template (runtime: memoize the default VM template; build stdlib tables one-shot #398)
• VM dispatcher / call-convention overhead cuts (vm: cheaper call convention — one-allocation register files, static-arity opcodes, call_self fusion #405, vm: cut per-call and per-iteration overhead in the dispatcher #401)
• Compiler peephole pass + more work done once at compile time (compiler: peephole pass with fused and constant opcodes #403, compiler: stamp node ids once, at compile time #416, compiler: key scope resolution by node id and dedupe upvalue descriptors #400, lexer: slice tokens from the source binary; drop per-char position maps #399)

Fixed

• Comments between a bare return and its terminator now parse (fix(parser): allow comments between a bare return and its terminator #418)
• ^ anchor honoured in string.gsub; literal caret in string.gmatch (fix(pattern): honour ^ anchor in gsub and literal caret in gmatch #406)
• No more unbounded recursion on cyclic tables at the eval boundary (Fix unbounded recursion on cyclic tables at the eval boundary #407)

The website-only playground change (#402) is intentionally omitted — it doesn't affect the published package.

Separately i'm running benchmarks to verify the 100x claim
