Make local-player analysis stack safe

[Frotty]

Summary

• replace recursive local-player IM indexing, return detection, short-circuit traversal, and loop-exit analysis with explicit worklists
• preserve the existing dependency/control-flow model while accepting deeply nested generated IM without overflowing the JVM stack
• retain useful exception types when compiletime failures have no message, and keep the Swing error window from opening synthetic compiler source locations as filesystem paths

Regression coverage

• constructs 20,000 nested IM conditionals inside a loop and runs LocalPlayerContextAnalyzer
• verifies message-less throwables report StackOverflowError instead of null
• verifies <source of NoExpr not found> is classified as synthetic rather than a source file

Checks

• focused local-player optimizer tests: passed
• focused compiletime diagnostic tests: passed
• focused error-window source test: passed
• affected map compiled successfully with -runcompiletimefunctions -injectobjects -lua -compiletimeCache -inline -localOptimizations

The full suite was intentionally left to CI because it is expensive; all directly affected suites were run locally.
