LibJS: Store bytecode cache indexes instead of pointers Store compact cache indexes in bytecode instructions instead of raw pointers to the executable cache vectors. This keeps the instruction stream independent from heap addresses and removes pointer fixups when materializing cached bytecode. Resolve the mutable cache pointers at execution time from the current Executable. Bytecode test expectations are updated for the smaller cache operands and resulting instruction offsets.

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.

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 source ranges from bytecode source maps Store source map locations as bytecode offset, line, and column. Runtime consumers only emit the start line and column, so source end positions and source text offsets do not need to be carried through Executable source maps, bytecode cache serialization, or the Rust FFI. Keep SourceCode's internal position cache able to track source text offsets so callers can still translate source offsets to line and column pairs when needed. Hash dump-bytecode IDs from the name, first source position, and bytecode size instead of source slices that need end offsets. Bump the bytecode cache format version for the slimmer serialized source map entry shape.
