[Jammy2211]

The course indexes still described the previous tutorial numbering and chapter structure. Align all four chapter indexes, optional tutorials and the course overview with the current HowToLens course, including evidence selection, Fit Problems and adaptive reconstruction. Current-course Colab links follow main; publication and test references retain their historical pins.

Part of PyAutoLabs/HowToLens#127.

API Changes

None — documentation only. No library Python, tests, configuration or public API changes.

Validation checklist

• Full library pytest: 1,021 passed, 1 expected failure (Python 3.12; full suite with -x).
• Both edited six-page documentation sets build with Sphinx/MyST and warnings as errors. This is a focused build, not the complete library autodoc build.
• Exact unique coverage of all 30 current HowToLens lessons; every destination resolves.
• Ecosystem audit: 52 repositories, eight actual task worktrees, 1,192 course URLs, no missing active destinations.
• Independent review: CLEAN; whitespace and documentation-only scope checks pass.
• Runtime smoke: n/a for this documentation-only change. The companion Lens notebook regeneration already passed its 44-entry smoke suite.
• Heart: STALE, release validation incomplete (no rehearsal for current source); no known-bad reason. Development PR only.

Coordination and dependencies

The user explicitly approved a separate documentation-only worktree while preserving magnification-maps-wiring's existing claim and changes. This branch changes only docs/howtolens/ pages; the other task's worktree and branch are untouched. No API dependency or workspace migration is introduced. Merge remains human /prm.

Full API Changes

None. Removed / added / renamed / changed signatures / changed behavior / migrations: none.
