- TARGETS.md: expand from 7 to 15 targets with correct phases, add Bugs/OQ/Gap tables synthesising all FV findings to date. - lean/lakefile.toml: remove Mathlib dependency while no .lean files exist; eliminates ~1 GB unnecessary download that blocked CI. - lean-proofs.yml: add weekly schedule trigger (Mon 07:00 UTC) for toolchain-drift detection; update elan version reference from v4.2.1 to v3.1.0 (matches tested version); add file-count metric to proof summary; emit informational step summary when no .lean files yet; use --no-modify-path in elan-init; replace word-boundary grep \<sorry\> (GNU only) with \bsorry\b (POSIX). 🔬 Lean Squad — automated formal-verification CI maintenance run.

Pull request overview
This PR updates the Lean formal-verification CI workflow to run on a weekly schedule and to improve the emitted job summary/metrics, alongside a small documentation tweak in the Lean Lake config.
Changes:
- Add a weekly scheduled trigger to
.github/workflows/lean-proofs.ymland enhance the “no .lean files” behavior with a step summary. - Update elan installation invocation (
--no-modify-path) and extend the proof summary with a Lean file-count metric. - Add a reference link comment in
formal-verification/lean/lakefile.toml.
