LibJS: Improve bytecode executable dump format Add a metadata header showing register count, block count, local variable names, and the constants table. Resolve jump targets to block labels (e.g. "block1") instead of raw hex addresses, and add visual separation between basic blocks. Make identifier and property key formatting more concise by using backtick quoting and showing base_identifier as a trailing parenthetical hint that joins the base and property names. Generate a stable name for each executable by hashing the source text it covers (stable across codegen changes). Named functions show as "foo$9beb91ec", anonymous ones as "$43362f3f". Also show the source filename, line, and column.

LibJS: Drop dead entry GetLexicalEnvironment loads Teach the Rust bytecode generator to treat the synthetic entry GetLexicalEnvironment as a removable prologue load. We still model reg4 as the saved entry lexical environment during codegen, but assemble() now deletes that load when no emitted instruction refers to the saved environment register. This keeps the semantics of unwinding and environment restoration intact while letting empty functions and other simple bodies start at their first real instruction.
