The first pass left three classes of config that BOTH tsc 5.9 and tsc 7
reject. Each was proven against both compilers before changing:
TS5090 A `paths` target must be relative once `baseUrl` is gone. The
first pass skipped the "./" prefix wherever baseUrl pointed at
the config's own directory, reasoning it was semantically
equivalent. It is not — without baseUrl a non-relative target
is rejected outright, by 5.9 as well as 7.
TS5110 `moduleResolution: node16` requires `module: node16`. The first
pass mapped commonjs projects to node16 resolution alone, which
BROKE those configs for the current toolchain. Both are now set.
TS5102 `downlevelIteration` is also removed in TS7; it was missing from
the dead-flag list.
Verified: repos that tsc 7 previously refused (base-studio, js-sdk, kv-js)
now report zero config errors on tsc 7 AND tsc 5.9.
