Addresses 3 findings from the automated review on PR #3874:
- Fully-qualified scopes (\App\Models\User::method() or
App\Models\User::method()) were left parked as unresolved: the class
lookup keyed on the full scope text, which never matches a class
node's own unqualified label. Now normalizes to the last namespace
segment before lookup.
- Method names were matched case-sensitively even though PHP method
calls are case-insensitive; a call spelled with different case than
the declaration silently produced no edge. The lookup key is now
lowercased on both sides.
- A lowercase-first class name (legal PHP, just non-PSR) fell through
the `receiver[:1].isupper()` gate into "dynamic scope" and was
dropped entirely. The gate is now `not receiver.startswith("$")`,
since a `$var::` scope is the only case actually requiring the
declared-type table this resolver doesn't have.
(cherry picked from commit 7ed0e1d70a)
scoped_call_expression (`Helper::format()`) used the scope text as the
callee name instead of the method name, so the shared cross-file
bare-name pass bound the call to whatever node shared the class's
label - almost always the class definition - never the actual method.
It also skipped member-call handling entirely, so the edge went
through the import-evidence confidence gate: same-namespace PHP
classes never need a `use` import for each other, so every
same-namespace static call was stuck at INFERRED 0.85 even though the
receiver class is named explicitly in source.
Capture the real method name as the callee and the scope as the
receiver, mark it a member call, and add a dedicated PHP resolver
(mirroring the existing Java/Swift/C++ member-call resolvers) that
binds self::/static:: to the enclosing class, parent:: through a
single inherits edge, and Class:: to the class's own method - all
EXTRACTED, since the receiver is named explicitly in source. A
dynamic scope ($var::method()) has no declared-type table to resolve
against and is left unresolved rather than guessed.
