fix: integrate reader navigation, shared panels and PDF import

[Eoic]

Summary

Integrate the complete reader workstream: accurate EPUB progress and covers, uninterrupted navigation, overlay controls, client-owned reader sheets, browser PDF import, and removal of pre-release compatibility shims. Record the current-contract policy in CODING_STYLE.md.

Update the client, reader and server submodules to the linked commits. Also capture the existing docs and website development revisions in the workspace; their component changes are already pushed.

Component PRs and merge order

1. Reader: fix: improve reader progress, navigation and host-owned panels reader#6
2. Server: refactor: remove legacy library payload promotion server#14
3. Client: fix: integrate reader sheets, PDF imports and current data contracts client#46 (pins the reader commit)
4. Merge this coordinating workspace PR after the component PRs.

Use merges that preserve the recorded component commits. No versions, releases or deployments are changed.

Validation

• Workspace committed-reference check passed: client manifest/lock and reader gitlink agree.
• Workspace tooling: 18 tests and ShellCheck passed.
• Reader: 170 tests, analysis, example checks, packaged worker check and browser smoke passed.
• Client: 1,620 tests passed with 19 skipped; 45 final focused regressions and 23 tests against the pushed reader dependency passed. Analysis, formatting, bootstrap checks and production web build passed.
• Server: 13 focused library validation/sync tests plus Ruff and Mypy passed.
• Real-book sessions ran in desktop Chrome and the actual client on an iOS simulator. Component reports describe evidence, reproduction and untested targets; live authenticated synchronization and physical-device certification were not performed.

All local source changes are committed. Ignored local overrides, private books, credentials and build artifacts remain untracked by Git. Remote CI status is reported separately by the linked PR checks.
