fix webassembly test bindings_wasm decodeText clash

[insipx]

bindings_wasm decodeText clashes with another declared function. I'm not sure if it was a function declared in bindgen or just the test runner, but changing decodeText to decodeXmtpText fixed it. In our code, i only found a single decodeText. I changed encodeText to encodeXmtpText for consistency

Error message ci/local tests failing with:

Uncaught SyntaxError: redeclaration of function decodeText

it looks like some internal bindgen/js glue code, here is the function its conflicting with for historical purposes (from the sourcemap in console).
mostly i'm surprised these functions are not prefixed with __ to avoid clashes like this

function getUint8ArrayMemory0() {
    if (cachedUint8ArrayMemory0 === null || cachedUint8ArrayMemory0.byteLength === 0) {
        cachedUint8ArrayMemory0 = new Uint8Array(wasm.memory.buffer);
    }
    return cachedUint8ArrayMemory0;
}

let cachedTextDecoder = new TextDecoder('utf-8', { ignoreBOM: true, fatal: true });

cachedTextDecoder.decode();

const MAX_SAFARI_DECODE_BYTES = 2146435072;
let numBytesDecoded = 0;
function decodeText(ptr, len) {
    numBytesDecoded += len;
    if (numBytesDecoded >= MAX_SAFARI_DECODE_BYTES) {
        cachedTextDecoder = new TextDecoder('utf-8', { ignoreBOM: true, fatal: true });
        cachedTextDecoder.decode();
        numBytesDecoded = len;
    }
    return cachedTextDecoder.decode(getUint8ArrayMemory0().subarray(ptr, ptr + len));
}

function getStringFromWasm0(ptr, len) {
    ptr = ptr >>> 0;
    return decodeText(ptr, len);
}

The fix is correct and necessary. The renaming from decodeText/encodeText to decodeXmtpText/encodeXmtpText properly resolves the name collision with wasm-bindgen's internal decodeText function.

Key Points:

✓ Code Quality: Clean implementation with appropriate error handling. The js_name annotation correctly exports the Rust functions with the new names.

✓ Naming Convention: The Xmtp prefix clearly distinguishes these from generic text encoding utilities and follows a reasonable pattern for avoiding conflicts in the global WASM namespace.

⚠️ Documentation Gap: Consider adding a brief comment in bindings_wasm/src/content_types/text.rs:22 explaining why the Xmtp prefix is used (similar to the comment on line 36-38 for decode), as this would help future maintainers understand the naming choice for both functions.

Test Coverage: No test files currently reference these functions. Since these were recently added in PR #2807, and this is purely a renaming change that fixes a build error, the lack of updated tests is acceptable for this fix. However, consider adding integration tests that exercise these functions in a future PR to ensure they work correctly in the WASM environment.

No security, performance, or bug concerns identified.

Rename WebAssembly exports in bindings_wasm/src/content_types/text.rs to fix build by changing wasm_bindgen js_name for encode_text to encodeXmtpText and decode_text to decodeXmtpText

Updates #[wasm_bindgen(js_name = ...)] on encode_text and decode_text to encodeXmtpText and decodeXmtpText in bindings_wasm/src/content_types/text.rs. Adds comments noting a name conflict.

📍Where to Start

Start with the #[wasm_bindgen] exports for encode_text and decode_text in bindings_wasm/src/content_types/text.rs.
