fix(javascript): preserve loader authority for exact suffixes (#9477)
* fix(javascript): require exact loader suffix case * fix(javascript): share exact loader mode across import resolution * test(process): align symlink fixture with filesystem checkpoints * test(javascript): normalize the module resolution oracle path separators * test(frida): assert the CLI spawn Evidence contract * test(mcp): use an unsupported analysis-view parent * test(browser): separate source-location line bounds from parity * fix(javascript): preserve uncertain loader provenance * test(javascript): cover uncertain require resolution * fix(javascript): retain conditional Electron evidence * fix(javascript): preserve timed semantic provenance * fix(javascript): retain conditional builtin effects * test(javascript): distinguish bundled host authority * fix(javascript): preserve nested loader invocation identity * test(javascript): qualify Electron fixture authority * fix(javascript): preserve loader invocation authority * fix(javascript): respect source order for resolver escapes * fix(javascript): check nested loader callable mutations * fix(javascript): retain conditional constructor requests * fix(reference): retain constructor loader relationships * fix(reference): follow nested loader callable paths * refactor(javascript): share callable mutation interpretation * fix(javascript): require exact package loader suffixes * refactor(javascript): unify conditional relation evidence * refactor(javascript): unify conditional node evidence * fix(javascript): retain unknown authority for mixed case sources * fix(javascript): preserve loader uncertainty for dotfiles * fix(reference): classify javascript suffix dotfiles * test(reference): cover suffix dotfiles through cli * fix(javascript): retain equivalent conditional built-in origins * fix(javascript): preserve wrapped resolver operation * fix(javascript): retain nested conditional built-in receivers * test(javascript): declare CommonJS in native addon fixtures * fix(javascript): retain wrapped resolver candidates * style: format merged native command schema * fix(javascript): preserve uncertain loader authority * test(javascript): require candidate preload evidence * test(javascript): cover reference loader member writes --------- Co-authored-by: ShuaixinHuang <1836656514@qq.com>
