* refactor(#2373): cutover resolve/git/config/research host routers (ADR-2346 P3)
Relocate 13 case arms from runCommand's switch to HOST_COMMAND_ROUTERS:
- resolve: resolve-model, resolve-granularity, resolve-execution (3)
- git: git (1)
- config: config-ensure-section, config-set, config-set-model-profile,
config-get, config-new-project, config-path, migrate-config (7)
- research: research-store, research-plan (2)
Each case body moved verbatim to a module-scope route*Command function
(closures over config/commands/output/_dispatchNonFamily preserved).
dispatchHostCommand extended to pass defaultValue + workstreamContext
(needed by config-get and config-path). No new files, no logic change.
Closes#2373
* chore: retrigger CI
