Johnpaul Chiwetelu df712953a3 [fix] Replace eval() with safe math expression parser (#9263)
## Summary
Replace `eval()` in `evaluateInput()` with a custom recursive descent
math parser, eliminating a security concern and enabling the `no-eval`
lint rule.

## Changes
- **New**: `mathParser.ts` — recursive descent parser for `+`, `-`, `*`,
`/`, `%`, `()`, decimals, unary operators. Zero new dependencies.
- **Modified**: `widget.ts` — replaced `eval()` call with
`evaluateMathExpression()`, use `isFinite()` instead of `isNaN()` to
reject `Infinity`
- **Modified**: `.oxlintrc.json` — `no-eval` rule changed from `"off"`
to `"error"`
- **Tests**: 59 parser tests + 23 integration tests covering complex
expressions, edge cases, and invalid input

## Review Feedback Addressed
- Renamed `unit()` → `primary()` for clarity
- Added modulo (`%`) operator support
- Normalized negative zero to positive zero
- Added depth limit (200) for nested parentheses
- Used `isFinite()` instead of `isNaN()` to reject
`Infinity`/`-Infinity`
- Added tests for edge-case number formats, unary-after-binary
operators, modulo, depth limits, scientific/hex notation, and `Infinity`
