Document the trip publish-toggle cache-invalidation finding: an in-place
trip.md `published` edit under cache.check.method: folder + APCu driver stays
stale because the folder checksum is unchanged AND the web APCu store is
unreachable by a CLI clearcache — fixed with apcu_clear_cache() from the web
request. Cross-link the sibling grav-deleteall doc (the create/delete case) as
necessary-but-not-sufficient here, and add the Published/Draft trip status
concept to CONCEPTS.md.

Document why deleteAll() alone left a freshly-posted entry 404-ing on its
edit-prefill API lookup (regular-pages index keyed on config->checksum, which
survives a create under cache.check.method:folder) and why the fix adds
Cache::invalidateCache(). Note the H1/M8 travelling:true coverage gap as a
tracked residual. Cross-link from bugs-and-fixes.md.
Code review F8 (learnings) + F5 (residual-gap tracking).
