Task 8: codemod repointed 150 namespace-type files to #/lexicons (AppBskyFeedDefs.PostView -> app.bsky.feed.defs.PostView, .Record -> .Main) plus ~105 hand-fixed consumers (composer/video state, DebugMod, Profile, onboarding, dialogs). DM_SERVICE_HEADERS deleted; last chat call sites on the chat client. RichText.tsx flipped to SDK-only. Remaining @atproto/api importers: the three session bridge files, the deliberate dual-world matcher in lib/xrpc-error.ts, and test fixtures. toLex boundary casts are TODO(phase4)-tagged for bridge removal.
