SWMC Lite Custom Pause Routine For P1 Series & Bambu Studio

Initial release - Bambu Studio variant of the SWMCL Pause Preset for P1 Series.

- First field test of the SteinSwitch Definition (SSD) architecture; proven here on a narrow feature set before rolling out across the full SWMC codebase in Core 1 three weeks later.
- New pause routine takes over the slicer's inserted pause, preventing the stock routine from dragging purge into the print area.
- 6 SSDs available: swmc_pause_routine, force_spiral_lift_for_pause, purge_with_25/50/75_percent_flow, use_hf_nozzle.
- Always-on anti-strip safety fallback at F499 protects standard 0.4mm+ nozzles from filament stripping when no flow-control SSD is enabled.
- Purge flow SSDs calculate dynamically based on filament max volumetric flow, so flow rates adapt to your specific material settings.
- `lower_bed_on_pause` from the Orca variant is not available. BBS does not expose the bed-position variable in Pause gcode.
- Light-control SSDs (`use_purge_work_light` and `dark_mode`) from the X1C variants are not available. P1 Series hardware limitations prevent these features from applying.

This is the Bambu Studio release of the SWMCL Pause Preset for the Bambu Lab P1P and P1S. Paste the gcode into the Pause G-code field of your Bambu Studio preset and configure via SSD keywords in printer notes.

This is the most narrowly-scoped variant in the four-release SWMCL Pause Preset family. The combined slicer and printer limitations mean you get 6 SSDs rather than the 9 available on the X1C + Orca combination. What's present works reliably; the core value proposition of a cleaner pause routine, purge flow control, and anti-strip safety is fully delivered here.

What's NOT available compared to other variants in this family:
- `lower_bed_on_pause` - requires Orca Slicer; use the Orca P1 variant if you need this
- `use_purge_work_light` and `dark_mode` - require the X1C's specific light hardware

The full routine addresses common stock pause problems: purge drags into the print area, no flow control on resume. These are solved here with SSD keywords letting you pick which behaviors you want, and the default anti-strip safety fallback protects standard 0.4mm+ nozzles without any user configuration required.

If you're already running a full SWMC Machine Preset on your P1 Series, you don't need this; the full preset includes this functionality. This release is for users who want the improved pause behavior without committing to the full machine preset.
