test(packaging): give the shared-detector fixtures the LICENSE the checkers now require

The clean-content case in forbidden-content.test.ts exits 1 on "Missing
required file in MCP package: LICENSE" instead of reaching the content read,
because this change gave the MCP checker a required-file guard it never had.

REACHABLE_FILES documents itself as "a minimal file list that passes each
checker's path/allowlist/required-file guards, so the run reaches the shared
secret-content read" -- LICENSE now belongs in it. Added to the miner list too,
so the list stays honest about the guards it claims to satisfy rather than
depending on that checker reading content before it checks required files.
