Add resample_interval parameter to Profiler HTML output methods

[Copilot]

The HTMLRenderer now accepts a resample_interval parameter to handle large sessions (>100k samples), but the Profiler convenience methods weren't exposing it, causing test failures.

Changes

• Added resample_interval parameter to Profiler.output_html(), Profiler.write_html(), and Profiler.open_in_browser()
• Parameters are passed through to the HTMLRenderer constructor

Usage

profiler = Profiler()
# ... profile code ...

# Control resampling behavior for large sessions
profiler.output_html(resample_interval=0.01)  # Use specific interval
profiler.write_html('output.html', resample_interval=0)  # Disable resampling
profiler.open_in_browser(resample_interval=None)  # Auto mode (default)
