Task 19: WASM Flag Syntax

Wave: 4 (WASM API Parity)
Category: unspecified-high
Parent: Epic #37

Problem

JavaScript regex uses /pattern/flags syntax. WASM bindings should support this for JS compatibility.

What to do

Add lexer/parser support for /pattern/flags syntax
Flags: g=global, i=ignorecase, m=multiline, s=dotall, u=unicode, y=sticky
Expose in WASM

Acceptance Criteria

new JsRegex("/abc/i") matches "ABC"
new JsRegex("/^a/m") matches "x\na"
new JsRegex("/./s") matches "\n"
new JsRegex("/abc/gi") matches all case-insensitive
new JsRegex("/abc/y") sticky matching works
