fix: use prefix matching for NEVER_AN_ENTITY to cover this.entity_id* variants

[kschlichter]

Problem

this.entity_id was added to NEVER_AN_ENTITY in #1515 to suppress false-positive "missing entity" repairs for custom cards that use it as a template placeholder. However, some custom cards (e.g. custom:easy-layout-card combined with custom:mini-graph-card) use numbered variants such as this.entity_id1, this.entity_id2, etc. as secondary placeholder variables. These are not covered by the exact-match frozenset and continue to be flagged.

Solution

Convert NEVER_AN_ENTITY from a frozenset exact-match to a prefix tuple renamed NEVER_AN_ENTITY_PREFIXES, checked with str.startswith(). Both this and trigger are never valid Home Assistant entity domains, so any string beginning with this.entity_id or trigger.entity_id is guaranteed never to be a real entity.

Changes

• entity_filtering.py: rename constant to NEVER_AN_ENTITY_PREFIXES, change from frozenset to tuple
• template_extraction.py: update import and all checks to use startswith()
• action_extraction.py: update import and all checks to use startswith()

Result

Value	Before	After
this.entity_id	✅ ignored	✅ ignored
trigger.entity_id	✅ ignored	✅ ignored
this.entity_id1	❌ flagged	✅ ignored
this.entity_id2	❌ flagged	✅ ignored
sensor.real_entity	✅ checked	✅ checked

📝 Walkthrough

Walkthrough

Entity reference filtering now uses reserved prefixes. Plain strings, dictionary-form entities, known entity IDs, and template-extracted candidates are excluded when they start with trigger.entity_id or this.entity_id.

Changes

Entity reference prefix filtering

Layer / File(s)	Summary
Reserved prefix filtering custom_components/spook/entity_filtering.py	Defines NEVER_AN_ENTITY_PREFIXES and filters known entity IDs with startswith.
Extraction path updates custom_components/spook/action_extraction.py, custom_components/spook/template_extraction.py	Applies prefix filtering to plain strings, dictionary-form entities, and template-extracted entity candidates.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 0e930

This change prevents numbered trigger and this placeholders from being treated as missing entities across filtering and extraction paths. The implementation is consistent, but explicit regression coverage for the newly supported numbered forms is still needed to guard the intended behavior.

Add regression cases for numbered reserved references.

The startswith(NEVER_AN_ENTITY_PREFIXES) guard excludes trigger.entity_id2 and this.entity_id1, but current tests cover only exact forms. Add explicit assertions for both references in the known-entity filter, async_extract_entities_from_action_config, and template extractor. Include a real entity in each input.
