* fix: plan-phase Nyquist validation when research is disabled (#980)
plan-phase step 5.5 required Nyquist artifacts even when research was
disabled, creating an impossible state: no RESEARCH.md to extract
Validation Architecture from. Step 7.5 then told Claude to "disable
Nyquist in config" without specifying the exact key, causing Claude to
guess wrong keys that config-set silently accepted.
Three fixes:
- plan-phase step 5.5: skip when research_enabled is false
- plan-phase step 7.5: specify exact config-set command for disabling
- config-set: reject unknown keys with whitelist validation

* test: update config-set tests for key whitelist validation
Tests that used arbitrary keys (some_number, some_string, a.b.c) now
use valid config keys to test the same coercion and nesting behavior.
Adds new test asserting unknown keys are rejected with error.

- branching_strategy assertion changed from strictEqual 'none' to typeof string check
- plan_check and verifier assertions changed from strictEqual true to typeof boolean checks
- Add isolation comments to three tests that touch ~/.gsd/ on real filesystem
- Full test suite passes: 433 tests, all modules above 70% coverage
