This PR expands the test coverage for the Eldritch DSL, specifically focusing on f-string expression parsing. It introduces a new test file fstrings_coverage.rs covering various scenarios including nested expressions and edge cases.

During testing, a bug was identified where tokenize_fstring_expression in the lexer naively counted braces without respecting string boundaries, causing expressions like f"{'}'}" to fail. This PR includes a fix for this issue by implementing a state-aware scan that skips string literals when counting braces.

This addresses the goal of increasing test coverage and stability for high-complexity modules.

- Added `implants/lib/eldritch/eldritch-core/tests/fstrings_coverage.rs` with comprehensive tests for f-string interpolation, nested expressions, function calls, and edge cases.
- Modified `implants/lib/eldritch/eldritch-core/src/lexer.rs` to implement smarter brace counting in `tokenize_fstring_expression`. The lexer now correctly skips string literals (single and double quoted) when finding the end of an f-string expression, preventing premature termination when a closing brace appears inside a string literal (e.g., `f"{'}'}"`).
- Documented known limitation regarding multiline f-string expressions in the test file.
- Verified changes with 20 repeated runs of the new tests and a full regression run of `eldritch-core`.
