Add the browser front end: create/run/delete the hist_browser and add the title. The d shortcut opens the existing per-cacheline detail view for the selected level-3 cacheline. Level-3 entries retain the source cacheline index, so the shortcut can locate the original entry without relying on a potentially ambiguous virtual address. Report a warning when the common model rejects a cacheline coalescing field list without `iaddr`. Without it, the detail histograms may already have merged samples from different functions and cannot support reliable function attribution. Keep visible-row accounting local to the function view by wrapping the generic browser refresh callback and recounting the currently reachable hierarchy before each redraw. This keeps navigation correct when a level-1 row is collapsed while level-3 descendants remain expanded, without adding C2C-specific hooks to the shared hist_browser. Also handle Ctrl-C like the other function-view exit keys. Keep callchains hidden while the function browser runs, restoring the user's setting while opening the cacheline detail view. Wire the builder into perf_c2c__browse_function_view().
