[codex] Refactor message and push presentation

[ohong]

Summary

• Split the oversized messages inbox into a stateful container plus focused message presentation and attachment utilities, bringing the main component under the 1k-line review threshold.
• Added a shared clipboard feedback hook and reused it across landing, feed, post creation, and profile invite copy flows.
• Moved CLI push summary/plain-text rendering into a dedicated output helper so push orchestration stays focused on sync behavior.

Why

This came out of a thermo-nuclear code quality review across landing page, web app, and CLI. The selected changes reduce structural complexity without changing product behavior: the web app sheds a >1k-line component hotspot, repeated clipboard timer logic is centralized, and CLI output rendering no longer sits inside the sync command's control flow.

Validation

• bun vitest run tests/components/MessagesInbox.test.tsx (apps/web)
• bun vitest run tests/commands/push.test.ts (packages/cli)
• bun run typecheck (apps/web)
• bun run typecheck (packages/cli)
• bun run lint (apps/web)
• bun run test (apps/web): 69 files / 590 tests passed
• bun run test (packages/cli, unsandboxed for local 127.0.0.1 bind): 21 files / 278 tests passed
• bun run build (monorepo): 3 tasks successful

Notes

• The initial sandboxed monorepo test run failed because CLI API tests could not bind 127.0.0.1; rerunning the CLI package tests outside the sandbox passed.
• packages/cli/src/lib/ccusage.ts has an unstaged local change that is not part of this PR.
