Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data. For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

No successful run was found on master ( d4b7a65) during the generation of this report, so 75b07b3 was used instead as the comparison base. There might be some changes unrelated to this pull request in this report.

perf(core): precompile hex color regex pattern at module level Move _HEX_COLOR_PATTERN regex compilation from inside _render_mermaid_using_api() to module level. This avoids recompiling the regex on every function call, improving performance when rendering multiple Mermaid graphs. Also combined nested if statements per SIM102 lint rule.
