Adopt credential safe CI and retire replaced source gitlinks

Why:
Make independent version consumption work from ordinary clones while retaining historical commits and existing branch workspaces.

Evidence:
SELF Dev task receipts record 24 CI boundary cases, all workflow syntax checks, readonly private-source prefetch in clean exports, provider tests and package installation without acquisition scripts. Platform CI remains pending.

Impact:
Remove only replaced index links, preserve old physical checkouts, and update dependency guidance. Library consumers retain their immutable versions until an explicit dependency update.
