Rudra Tiwari 451e8496e7 perf(core): precompile hex color regex pattern at module level (#34480)
Moves hex color validation regex from inside
`_render_mermaid_using_api()` to module-level constant
`_HEX_COLOR_PATTERN`. This avoids recompiling the regex on every
function call, improving performance when rendering multiple Mermaid
graphs.


**Testing:**
- `make lint` passes
- `make test` passes
