"Snapmaker PLA-CF @U1" and "Snapmaker PLA-CF @U1 0.4 nozzle" are the same
product on the same printer: both pin "Snapmaker U1 (0.4 nozzle)", and only a
filament_id salt split kept them apart. The first came with the original U1
profiles (#10225); the second with the tool-changer rework (#15039), which
added the 0.4/0.6/0.8 nozzle variants and left the older preset behind.
Drop the older one and re-mint the 0.4 variant onto OFhQf8ou, the id its 0.6
and 0.8 siblings already carry, so the product holds one id across the three
nozzles; renamed_from redirects the retired name. Users of the retired preset
get the #15039 tuning - 39 keys differ, including nozzle 230 -> 240 C, plate
55 -> 65 C and vitrification 150 -> 45 C - which is what the 0.6 and 0.8
variants already ship.
"Snapmaker PLA-CF @U1 base" stays. #15039 orphaned it by having the nozzle
variants inherit fdm_filament_pla directly, so it is unreferenced, but it is a
base in the vendor's own convention - 10 of the 14 @U1 families with nozzle
variants wire them to one - and it holds U1 loading and cooling values the
variants never set. Wiring them to it would change slicing output, which is
Snapmaker's call to make, not this PR's.

* update snapmaker profiles. largely ported for Snapmaker Orca fork
* update prime volume
* set precise_outer_wall to 1
* Update per-material multi-tool ramming to the filament library
* Add per-filament overrides for toolchange retraction
* Set toolchange retraction per filament for Snapmaker U1
* set default support type to tree
* format snapmaker profiles
* profiles: enforce globally-unique, per-vendor-namespaced setting_id
Many non-Bambu vendors copied Bambu's generic setting_ids (GFSA04 alone
appeared in 1557 files), so setting_id was not globally unique. This
namespaces every vendor's ids and reserves Bambu/OrcaFilamentLibrary space.
- Reserve "G*" (Bambu) and "O*" (OrcaFilamentLibrary) id spaces.
- Assign each other vendor a 2-char prefix (first+last letter, collision
resolved) and renumber every instantiated preset to <PREFIX><NNNN>.
- Strip setting_id from base profiles (instantiation:false) per Bambu's
convention; assign one to instantiated presets that lacked it.
- Remove the pre-existing misspelled "settings_id" key (91 files).
- filament_id is left untouched (it is a per-material id).
- Add one-time migration script scripts/assign_vendor_setting_ids.py with a
persisted registry resources/profiles/vendor_prefixes.json. Re-runs freeze
existing ids; only new vendors/profiles get new ids.
- Bump version in each changed vendor index file.
- Extend scripts/orca_extra_profile_check.py with a CI guard: global
uniqueness, in-namespace, no base setting_id, no gaps, no settings_id typo.
7425 profile files changed across 61 vendors; 0 cross-vendor collisions;
validator clean; migration idempotent. BBL and OrcaFilamentLibrary id spaces
untouched.
* profiles: add setting_id authoring guide for new vendors / profiles
* profiles: drop in-repo README; setting_id guide now lives in the wiki
* profiles: derive setting_id deterministically from vendor/type/name
* bump profile version
fix(profiles): add printable_area to fdm_U1 so all nozzle variants inherit correct 270x270 bed
The 0.2/0.6/0.8 nozzle profiles inherit from fdm_U1 which had no
printable_area defined, causing them to fall back to a smaller default
bed size. The 0.4 profile was the only one that set it explicitly.
Move printable_area and printable_height to the shared parent (fdm_U1)
so all Snapmaker U1 nozzle variants get the correct 270x270mm bed.
Bump vendor version to trigger profile re-sync on existing installs.

* Snapmaker U1: add 0.2mm and 0.8mm nozzle profiles
Add machine and process profiles for the Snapmaker U1's 0.2mm and
0.8mm nozzles, and complete the 0.6mm process lineup. Follows the
same data-only pattern used to add the 0.6 / 0.4+0.6 nozzles in
commit afc3756.
The U1 ships with 0.4, 0.4+0.6 and 0.6 nozzle options today; the 0.2
and 0.8 nozzles are supported hardware but have no profiles, so they
cannot be selected. This adds them the Orca-native way: per-nozzle
machine presets plus a model-file dropdown entry, with their process
profiles filtered in via compatible_printers.
Machine (2): lean presets inheriting fdm_U1, mirroring the existing
SM_U1_06 (0.6) preset and overriding only the per-nozzle values;
setting_ids SM_U1_02 / SM_U1_08.
Process (21): 2 per-nozzle commons (fdm_process_U1_0.2_common,
_0.8_common) holding the nozzle line widths, plus 19 profiles
(0.2: 8, 0.6: 6, 0.8: 5) that inherit their per-nozzle common and
carry their own layer height, matching upstream's factoring. The two
0.24 Standard profiles that shared id GP029 are split into
GP029_06_024 / GP029_08_024.
Model dropdown: machine/Snapmaker U1.json nozzle_diameter
"0.4;0.4+0.6;0.6" -> "0.2;0.4;0.4+0.6;0.6;0.8".
Vendor index: register the new presets in Snapmaker.json.
The existing 0.4 / 0.6 / 0.4+0.6 presets resolve identically before
and after. scripts/orca_extra_profile_check.py and the profile
validator both pass.
* chore(profiles): bump Snapmaker vendor version to 02.04.00.04
Bump the Snapmaker vendor config_version so existing installs pick up the new 0.2mm and 0.8mm U1 nozzle profiles. PresetUpdater only re-imports a vendor bundle when the shipped version is strictly greater than the cached one.

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.
