 226e95f734 feat(profiles): add Lulzbot Mini 1 (#15476) 
Adds the LulzBot Mini 1 (single extruder, 0.5 mm nozzle, 2.85 mm filament)
to the existing Lulzbot vendor, which previously shipped only TAZ models.

Values are taken from LulzBot's own current slicer configuration
(github.com/lulzbot3d/CuraLE) rather than estimated:

  - geometry and custom g-code from resources/definitions/single_mini_mini_1.def.json
    and resources/gcodes/mini_1/{mini_1_start,mini_1_end}.gcode
  - filament temperatures and cooling from resources/materials/*.xml.fdm_material,
    overridden by resources/quality/single_mini/<material>/*.inst.cfg

The start g-code reproduces the Mini's nozzle wipe and four-washer G29 probe,
with the filament-type temperature conditionals used by the sibling TAZ profiles.

One deliberate departure from current CuraLE: the pre-wipe retract is 30 mm,
the value used by Cura LE 4.13.x, rather than the 4 mm current CuraLE uses.
The Mini probes by electrical contact between nozzle and washer, so the nozzle
must stay clean through the wipe and all four touches. At 4 mm the melt zone
stays full and can ooze onto a washer, which caused auto-levelling failures on
hardware; 30 mm empties it. The cost is a ~24 s purge at print start.

The three filament presets follow docs/HLSD/filament_id.md rule 4: a vendor
tuning a generic material inherits Generic X @System, keeps the Generic X base
name and declares no filament_id, so identity stays with OrcaFilamentLibrary.
Their compatible_printers is the Mini alone, disjoint from Generic X @Lulzbot
(TAZ only) as rule 3 requires. They exist because temperature is a filament-scope
setting, so LulzBot's values need printer-scoped presets. All six plate types
carry the same temperature, because the Mini has a single bed and curr_bed_type
can hold a stale value carried over from another printer.

Strictly additive: no existing profile is modified, so TAZ behaviour is
unchanged and no migration is required. Lulzbot.json is bumped to 02.04.00.05.

Verified with scripts/orca_profile_tool.py check and scripts/check_profile.sh
on the full tree (profile tool, system validation, slice, filament subtypes and
custom-preset fixtures all pass), by diffing sliced output against LulzBot's own
Cura LE g-code for the same model and filament (temps, retraction, speeds and
the full wipe/probe sequence match), and by printing a 3DBenchy on a Mini 1 over
OctoPrint.
