The SPARKX i7 machine presets shipped (via #13947) with a contributor's
LAN IP (http://10.10.1.39) hardcoded in print_host. Remove it to match
the K2/K2 Pro/K2 Plus presets, which carry no print_host key — LAN
discovery + the crealityprint agent populate the host at add-printer time.
This updates the SPARKX i7 from a "regular" klipper printer to use the
new CrealityPrinter agent, that talks to it's "supervisor" webserver
instead, and can use the native Creality features: CFS, filament
querying, filament remapping, etc...
The CFS-aware filament sync resolves its agent via switch_printer_agent(),
which reads the preset's `printer_agent` field and falls back to "orca" when
unset -- so the K-series presets need printer_agent="crealityprint" (the id
registered by CrealityPrintAgent) in addition to host_type="crealityprint"
(classic PrintHost/LAN-discovery). Without printer_agent the Device-tab sync
defaults to the Orca agent and CFS sync doesn't engage. Set both on the
F008/F012/F021 models that supports_multi_color_print() covers (not K2 SE).
Both keys are in s_PhysicalPrinter_opts, so a new Physical Printer inherits
them from the preset.
* K2 Plus: add print area bounding box for adaptive bed mesh
The K2 firmware reads MINX/MINY/MAXX/MAXY gcode comments to
determine the adaptive bed mesh area. Without these, it falls
back to full bed mesh even when calibration is enabled.
K2 Pro also reads these comments (its profiles already had them).

* K2: add print area bounding box for adaptive bed mesh
Same change as K2 Plus — prepend MINX/MINY/MAXX/MAXY gcode comments
so firmware can determine the adaptive bed mesh area.
K2 Pro already had these.

Fix Ender-3 V3 KE nozzle switching by adding printer_variant
The four Creality Ender-3 V3 KE 0.X nozzle profiles were missing the
printer_variant key, so OrcaSlicer could not map a UI nozzle selection
to a specific profile and reverted every choice to 0.2mm. Add the
matching printer_variant to each, following the CR-10 SE / K1C pattern.
Reduce the size of current and new JSONs by standardising them with 1 tab indentation instead of 4 spaces.
This effectively reduces the size by almost 20 MB.
| Current | New |
|---|---|
| 85.2 Mib | 67 Mib |
Used [JQ](https://jqlang.org/) `--tab` to automatically format every current JSON.
> [!NOTE]
> Some profiles had the arrays on the same line, but those created by Orca were in the standard format (each object below the previous one). In some cases, this increases the number of tabs due to the new lines, but the increase is negligible, and this way both the base profiles and those created by Orca maintain the same style.
## Problem
Some Creality printers (e.g. Ender-3 V3 SE) rely on metadata comments in the first lines of G-code files to display print info on the screen (estimated time, filament usage, layer height). This follows a format originally used by Cura/Creality Print:
```
;FLAVOR:Marlin
;TIME:3708.97
;Filament used:6.21m
;Layer height:0.2
```
OrcaSlicer currently has no way to write content before the `HEADER_BLOCK` in the G-code output, and does not expose `print_time_sec` or `filament_length_m` as usable placeholders. As a result, these printers show zeroed-out print info on screen.
## Changes
### 1. New placeholders (post-processing)
Added two new G-code placeholders resolved during post-processing:
- `{print_time_sec}` — total estimated print time in seconds (double)
- `{filament_length_m}` — total filament length in meters (double)
These values are only available after G-code generation, so they use inline marker replacement (`@PRINT_TIME_SEC@`, `@FILAMENT_LENGTH_M@`) that `GCodeProcessor::run_post_process()` substitutes with actual computed values — the same pattern used by existing M73 and layer count placeholders.
### 2. New "File header G-code" option (`machine_top_gcode`)
Added a new G-code field in **Printer Settings > Machine G-code** that writes content at the very top of the output file, before `HEADER_BLOCK_START`. This allows users to add firmware-specific metadata that must appear in the first lines.
### 3. Creality Ender-3 V3 SE profile update
Pre-configured the Ender-3 V3 SE profiles (all 4 nozzle variants) with a default `machine_top_gcode` value matching the Cura-compatible header format, so print info displays correctly out of the box.

## Tests
- Sliced test model with Ender-3 V3 SE profile
- Verified G-code output contains correct values in first lines:
- `;TIME:` with actual print time in seconds
- `;Filament used:` with filament length in meters
- `;Layer height:` with correct layer height
- Verified `{print_time_sec}` and `{filament_length_m}` work in both Machine Start G-code and File header G-code fields
- Verified empty `machine_top_gcode` produces no extra output
- Built and tested on macOS (arm64)
* Profiles for Creality K2 Pro printer
Added printer profiles for Creality K2 Pro based on existing K2 Plus profile and Creality Print modifications.
* Fixed filament start g-code for K2 series
K2 Plus filament profiles have additional move for filament start g-code on some filaments. This causes unnecessary moves and make filament profiles non-working on K2 series printers.
As these moves are already mirrored on printer profile and not used in rest of the K2 series they should be removed.
* Update Creality K2 Pro profiles for improved print quality
Added adaptive probing comments to machine start gcode for all nozzle sizes. Adjusted process profiles for various layer heights and nozzle sizes, including changes to bridge speeds, acceleration, wall generator and support line widths according to Creality profiles s to optimize print quality and reliability.
* Revert "Update Creality K2 Pro profiles for improved print quality"
This reverts commit ac84058c33350307a1ac23ac939d3294ae2f9c96.
* Update Creality K2 Pro profiles for improved slicing
Adjusted speeds, accelerations, line widths, and other slicing parameters for better print quality and compatibility. Updated machine start g-code to include print area comments for adaptive probing (Creality K2 Pro uses these comments to define adaptive probing area)

Using my Ender 3 V3 SE I noticed weird printing behaviour. Searching for
the cause, I found that the default layer height for a 0.2mm nozzle for
the printer was set to 0.08mm min and 0.32mm max, which are the default
20%/80% values for a 0.4mm nozzle. This commit changes the values for
all Creality printer which had not a reasonable default value for 0.2mm,
0.6mm and 0.8mm nozzles to 20% min and 80% max.
