Introduce a dedicated utility that probes browser support for AAC/WebCodecs audio settings instead of assuming a single hardcoded configuration (`mp4a.40.2`, 192 kbps, stereo, 44.1 kHz). This file should centralize support detection and fallback selection so ChromeOS/Chrome variants that reject the current config can still export with audio.
Affected files: audio-codec-support.ts

* fix(security): replace new Function() with safe math expression parser
Replace the dangerous new Function() constructor in evaluateMathExpression()
with a recursive descent parser that safely evaluates basic arithmetic
expressions.
The Function constructor is a security anti-pattern that could enable
arbitrary code execution if the validation regex is ever bypassed or
relaxed. The new parser:
- Only supports numbers, +, -, *, /, parentheses, and whitespace
- Has no eval-like functionality that could execute arbitrary code
- Maintains backward compatibility with existing expressions
- Handles operator precedence and parentheses correctly
Fixes#725
* Apply suggestion from @coderabbitai[bot]

Introduce `bridge` proc-macro crate with `#[export]` attribute that conditionally applies `wasm_bindgen` for WASM builds, and `time` crate porting all timecode/frame utilities from TypeScript to Rust.
