Add gitlab, cloudflare, ghactions (MOCK-ONLY) and appsecret (LIVE-VM) one-file
Rotators, each with a table-driven cutover-proof + leak-check test. gitlab/
cloudflare/ghactions are in-place SaaS-token rolls (self/rotate, value-roll,
sealed-secret overwrite) so RevokeOld is a no-op; ghactions seals via
nacl/box.SealAnonymous (no new go.mod dep). appsecret regenerates a local app
signing secret and rewrites it in place across every target file (atomic, mode-
preserving, redacted errors), discoverable via exact-match app-signing key names
in env.go.
Keep real-rotation code distinct from mock code: how each driver's cutover was
validated lives as DATA in internal/rotate/proofs.go (single source of truth) +
docs/ROTATION-PROOFS.md, surfaced as a PROOF column in `incredigo rotate` so a
MOCK-ONLY driver can never be mistaken for a LIVE-VM one. appsecret proven LIVE-VM
against real local files in the sandbox VM.
82 tests green, -race clean on rotate/sink/vault.
