Deprecate package, merged into tomasvotruba/type-coverage

[TomasVotruba]

Rules were merged into tomasvotruba/type-coverage in 2.3.0. This marks rector/type-perfect as abandoned and documents the switch.

composer.json

-    "description": "Next level type declaration checks",
+    "description": "Next level type declaration checks - DEPRECATED, merged into tomasvotruba/type-coverage",
     "license": "MIT",
+    "abandoned": "tomasvotruba/type-coverage",

Composer now warns on every composer install that uses this package, and points at the replacement.

README

Warning admonition at the top + a "How to switch" section covering:

 "require-dev": {
-    "rector/type-perfect": "^2.1"
+    "tomasvotruba/type-coverage": "^2.3"
 }

• ignoreErrors and baselines need no change — rules keep the Rector\TypePerfect\ namespace in Type Coverage
• PHP requirement moves from ^8.2 to ^8.4
• The 3 rules that ran out of the box here are opt-in there:

 parameters:
     type_perfect:
+        no_param_type_removal: true
+        no_isset_on_object: true
+        no_empty_on_object: true

• Documented as not carried over: NoArrayAccessOnObjectRule, plus the fixes from NarrowPublicClassMethodParamTypeRule: Fix generic-object false-positive #74 and NoArrayAccessOnObjectRule: Skip Symfony DomCrawler AbstractUriElement and child types #77

Downgrade build removed

downgraded_release.yaml, build/ and full-tool-build.sh are gone — no more PHP 7.4 builds pushed to anywherephp/type-perfect.
