fix(output): llmstxt section header produces "Itemss" when entity_type unset

[greynewell]

Summary

• GenerateLlmsTxt builds the entities section header as entityLabel + "s"
• The fallback when cfg.Data.EntityType is empty was "Items" — already plural
• This produced "## Itemss" as the default heading when no entity type is configured
• Fix: change the default fallback from "Items" to "Item" so the computed header reads "## Items"

Test plan

• TestGenerateLlmsTxt_DefaultEntityType: fails with old "Items" default, passes with "Item"
• TestGenerateLlmsTxt_ConfiguredEntityType: entity_type: recipe → ## Recipes
• TestGenerateLlmsTxt_EntityLinks: entity URLs use correct format
• go test ./internal/archdocs/pssg/output/... passes
• go build ./... passes

Walkthrough

This change adjusts the default entity label in the llmstxt output generator from plural ("Items") to singular ("Item"), with corresponding test coverage added to validate pluralization behavior for default and custom entity types.

Changes

Cohort / File(s)	Summary
Pluralization Logic Update internal/archdocs/pssg/output/llmstxt.go	Changed default entityLabel from "Items" to "Item" when cfg.Data.EntityType is empty, affecting the generated section heading text.
Test Coverage internal/archdocs/pssg/output/llmstxt_test.go	Added unit tests validating default pluralization (checks for "## Items"), custom entity pluralization (e.g., "recipe" → "## Recipes"), and entity link rendering with URL and description fields.

Poem

Singular to plural, a label takes flight,
From "Item" to "Items"—the pluralization rite,
Tests guard the transformation with care,
Recipes dance where Items once were there. ✨
