docs(review): rename gittensory prose to loopover in src/review (batch A)

[JSONbored]

Summary

• Part of the gittensory→loopover rebrand (Epic: complete the gittensory -> loopover rebrand (full cutover, no dual-support) #5705), phase 8b: rename brand-name prose in comments across src/review/** — the reviewbot→loopover convergence-port modules (adapters, alerts, auto-apply/auto-tune, content-lane primitives), cutover-gate, enrichment wiring, feature activation, and related modules. Comment-only, no behavior change.
• Deliberately left untouched: the pre-rename GITTENSORY_LEGACY_* check-run name constants and their exact string values (check-names.ts), the 'gittensory-native' review_audit.source discriminator used across parity/outcomes tracking (a real DB column value, not prose — renaming it would desync new writes from historically-recorded rows), the x-gittensory-request-id header the engine sends to the REES enrichment service, and the ../config/gittensory-repo-focus-manifest import path (the module itself is still filed under its old name; renaming just the import string would break module resolution).
