0xdhx bc5c362610 fix(#2665): replace the hand-synced TEST_ENV_BASE copies with the canonical import
Eight declarations were kept in sync by hand with no parity assertion. The drift
was already in the tree: api-coverage-gate-e2e and representative-corpus declared
TERM_SESSION, but the real variable is TERM_SESSION_ID, so both scrubbed nothing
for that slot and leaked TERM_SESSION_ID into every child. Deleting the copies
removes the dead key with them -- there is no longer a second place to get wrong.

run-tests-harness keeps its local session-identity literal: that helper mirrors
the production runGsdTools to prove its CONTRACT, so it must not re-import what
it is testing. The config-LOCATION keys are a safety scrub rather than part of
that contract, so it spreads the canonical derived set and keeps the rest local.

Addresses review findings: Blocker 2, Blocker 3.
