Add 25 epithelium terms for mucosal structures

[Copilot]

UBERON had ~120 mucosa terms but only ~60 corresponding epithelium terms with proper part_of relationships, breaking the navigation path: mucosa → epithelium → cell types.

Changes

Added 25 new epithelium terms (UBERON:9900000-9900024) following the standard pattern:

[Term]
id: UBERON:9900000
name: epithelium of cecum mucosa
def: "An epithelium that is part of a cecum mucosa." [UBERON:automated]
intersection_of: UBERON:0000483 ! epithelium
intersection_of: part_of UBERON:0000314 ! cecum mucosa
relationship: part_of UBERON:0000314 ! cecum mucosa
is_a: UBERON:0003350 ! epithelium of mucosa

Coverage Added

GI tract (16 terms): cecum, colorectum, ascending/transverse/descending/sigmoid colon, stomach, small intestine, anal canal, rectum, esophagogastric junction, lower esophagus, alveolar

Respiratory (5 terms): trachea, bronchi, olfactory/respiratory segments of nasal mucosa, larynx

Urogenital (4 terms): urinary bladder, ureter, cervix, vagina, reproductive system

Terms Already Covered

• mouth mucosa → oral epithelium (UBERON:0002424)
• stomach glandular region mucosa → stomach glandular epithelium (UBERON:0006924)
• mucosa of large intestine → epithelium of large intestine (UBERON:0001278)

All terms validated with robot convert.

This section details on the original issue you should resolve

<issue_title>populate mucosal epithelium terms</issue_title>
<issue_description>Aim: Users querying for parts a specific mucosa should find the epithelium term and from there the cell types that are part of that epithelium

We have 120 mucosa terms:

But only 60 'epithelium of muscosa' terms

To fix:

• Generate lists of terms
• modify to isolate general anatomical component & align/diff.
• --> list of terms to add
• Remaining terms, review manually.

Comments on the Issue (you are @copilot in this section)

@dosumis Formal def:

Strategy for query with UberGraph:

1. Find all mucosa --> what they are part_of
2. Find all epithelia that are part_of these structures
   --> check if they are subClassOf "epithelium of mucosa"

FOr those that are not - we should be adding part relationship to the relevant mucosa term

Potential difficulty - UberGraph + reasoning will give too many results. Also do we want to add for all grouping terms?</comment_new>
