withTagSlots

Description#

Register app-wide template overrides for the five Tag-family slots. Resolved in tier 2 of the slot cascade — instance directives still win, the host's <ng-template> default body is the floor.

Staging note. This factory ships ahead of a documented second consumer — the headless CngxTag + CngxTagGroup are the only current consumers. The staging is intentional and tracked in display-accepted-debt.md §2 (Material organism deferral): a future cngx-mat-tag / cngx-mat-tag-group wrapper inherits the cascade for free without forking. If §2 is rejected outright, withTagSlots re-evaluates as a sunsetting candidate at the same time. Per the cngx-review architecture lens, the surface is tracked rather than left silent.
