# Description
Fixes user filament presets that reference an old printer preset name in
`compatible_printers`, even when the current system printer preset
correctly declares that old name in `renamed_from`.
## Core Issue
`PresetCollection::find_preset()` was updated to resolve `renamed_from`,
but this specific failure does not go through `find_preset()`.
For root user filament presets with empty `inherits`, Orca infers
`compatible_printers` from the filament name suffix after `@`. For
example:
```json
"ELEGOO PLA Base @Elegoo Neptune 4 Pro (0.4 nozzle)"
```
loads with:
```json
"compatible_printers": ["Elegoo Neptune 4 Pro (0.4 nozzle)"]
```
The current system printer preset is named:
```text
Elegoo Neptune 4 Pro 0.4 nozzle
```
and has:
```json
"renamed_from": "Elegoo Neptune 4 Pro (0.4 nozzle)"
```
However, filament compatibility was doing a direct string comparison
against the active printer name. Since that compatibility path does not
call `find_preset()`, the `renamed_from` mapping was never considered.
## Fix
Teach printer compatibility checks to treat
`active_printer.preset.renamed_from` entries as aliases of the active
printer name.
This preserves existing user preset JSON and avoids rewriting
`compatible_printers`, while allowing old printer suffixes to remain
compatible with renamed system printer presets.

* 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
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.

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.
