Remove deprecated refit_denovo_signatures parameter from sigprofiler_extract

[Copilot]

The refit_denovo_signatures parameter was removed in newer versions of SigProfilerExtractor, causing unused argument errors when users call sigprofiler_extract().

Changes

• Removed deprecated parameter from Python calls: Eliminated refit_denovo_signatures from both the direct sigpro$sigProfilerExtractor() call and the fallback command string
• Updated documentation: Marked refit parameter as deprecated with clear deprecation notice
• Maintained backward compatibility: Kept refit in function signature to avoid breaking existing code (parameter is now silently ignored)

Example

Users can now call the function without encountering parameter errors:

sigprofiler_extract(
  nmf_matrix = nmf_sample,
  output = "./sigprofiler/",
  genome_build = "hg19",
  use_conda = FALSE,
  py_path = "C:/path/to/python.exe",
  refit = FALSE,  # Now deprecated and ignored
  refit_plot = FALSE
)

The function will work with both older SigProfilerExtractor versions (that ignore missing parameters) and newer versions (that reject the deprecated parameter).

Additional

• Fixed typos: "sigantures" → "signatures", "decompostion" → "decomposition"

<issue_title>Refit error in sigprofiler_extract</issue_title>
<issue_description>I am getting two error when trying to run sigprofiler_extract. The first one is due to a possibly deprecated argument in SigProfilerExtractor called "refit". The second one is probably related to the fact that i am using a Windows PC.

I manually installed SigProfilerExtractor because conda was giving me another problems and that is why I have the python path option. I have tried this with and without the refit and refit_plot options.

> sigprofiler_extract(
+   nmf_matrix = nmf_sample,
+   output = "./sigprofiler/",
+   genome_build = "hg19",
+   use_conda = FALSE,  # do NOT auto-create environment
+   py_path   = "C:/Users/jrc356/.conda/envs/sigprofiler_env/python.exe",
+   refit  = FALSE,  # explicitly turn off refit so it won't pass that param
+   refit_plot = FALSE
+ )

Thanks! Cause the sigminer fits a fixed version of sigprofiler. We will take a look and see how we can solve it smoothly.</body></comment_new>
