Summary

• Floors rennf93/guard-core-php to ^4.3.0 and picks up the 4.3.0 engine train (spec 12 event bus with Redis-backed metrics persistence, spec 10 geo lifecycle, spec 04 redos gates + performance monitor, pattern_safety/events/redis_interop conformance runners). Nothing in the Symfony surface changes; the middleware is a thin adapter.
• CI engine sibling stamps move 4.2.99 -> 4.3.99 (ci.yml, release.yml, static-analysis.yml, upstream-drift.yml, scheduled-lint.yml); composer.lock resolves the engine at the released v4.3.0.
• CHANGELOG: v1.3.0 section covering the floor raise plus the released-but-undocumented delta since v1.2.0: the process scaffold (PR chore(scaffold): community health files, phpstan static analysis, advanced app smoke #16: community health files, phpstan level 3 static analysis, live-smoke-advanced job, semgrep as the CodeQL substitute) and the 100% line coverage gate (PR ci: enforce the 100% line coverage gate #17).

Verification

• Local gates on php 8.5.11: make lint exit 0, make test exit 0 (120/120 checks green), composer.lock resolves guard-core-php v4.3.0.

Test plan

• make lint exit 0
• make test exit 0
• CI green on the PR head
