* refactor(#60): make runtime config adapter registry explicit

Replace scattered inline `runtime === '...'` config-mutation branching in
bin/install.js with an explicit, typed adapter registry. The new
src/runtime-config-adapter-registry.cts maps each of the 15 supported
runtimes to a config intent { installSurface, writesSharedSettings,
finishPermissionWriter }; install()/finishInstall() dispatch by resolved
intent instead of runtime-name checks (cursor/windsurf/trae collapse to one
profile-marker-only branch).

Behavior-preserving: the same config files are written for the same runtimes
(opencode still writes both settings.json and its permissions; kilo writes
only its permissions; codex minimal-mode and opencode GSD_TEST_MODE guards
unchanged). Unknown runtimes fail loudly via TypeError, with an Object.hasOwn
barrier so prototype-chain keys (__proto__/constructor) also throw rather than
returning a bogus intent. Leads the installer-refactor chain (#58 -> #60 ->
#56), building on ADR-58.

Closes #60

* docs(#60): register Runtime Config Adapter Registry in CONTEXT.md glossary

Per docs/contributor-standards.md, every new Module/seam must get a
`### <Name>` entry under the domain glossary. Adds the entry for the
runtime-config-adapter-registry seam introduced in this PR (interface,
policy boundary, source file, ADR-58 / #60 cross-references).

Make per-runtime config-mutation dispatch in the installer explicit: a new runtime config adapter registry maps each supported runtime to a typed config intent (install surface, shared-settings gate, finish-phase permission writer), and `install()`/`finishInstall()` dispatch by resolved intent instead of inline `runtime === '...'` branching. Behavior-preserving; unknown runtimes now fail loudly. (#60)
<!-- docs-exempt: internal behavior-preserving refactor of bin/install.js config dispatch into a dedicated registry module; no user-facing behavior change -->
