SWMC Lite Custom Pause Routine For X1C & Bambu Studio

Initial release - Bambu Studio variant of the SWMCL Pause Preset for X1C.

- 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.
- 8 SSDs available: swmc_pause_routine, force_spiral_lift_for_pause, use_purge_work_light (X1C), dark_mode (X1C), 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 in this release. BBS does not expose the bed-position variable in Pause gcode, so automatic bed lowering is not possible in this slicer.

This is the Bambu Studio release of the SWMCL Pause Preset for the Bambu Lab X1C. Paste the gcode into the Pause G-code field of your Bambu Studio preset and configure via SSD keywords in printer notes.

The X1C in Bambu Studio gets the full light-control feature set: `use_purge_work_light` for chamber camera illumination during the purge cycle, and `dark_mode` for keeping the toolhead logo light off after resume. The `dark_mode` feature is worth calling out; the logo light can't be disabled through the printer menu, so this is the only way to resume overnight prints in a shared sleeping space without the bright light coming on.

The full routine addresses common stock pause problems: purge drags into the print area, no flow control on resume, no camera visibility during purge cycles. Each of these is solved here with SSD keywords letting you pick exactly which behaviors you want.

One feature not available in this BBS variant: automatic bed lowering on pause. The `lower_bed_on_pause` SSD requires Orca Slicer. If you need automatic bed lowering when inserting parts mid-print, use the Orca X1 variant of this release.

If you're already running a full SWMC Machine Preset on your X1C, 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.
