Add Tom's LQ permanent income trilogy of lectures (#943)
* Add Tom's LQ permanent income trilogy, replacing lq_consumption_smoothing
Splits the single lecture 'LQ Consumption Smoothing: Incomplete Markets,
Complete Markets, and Robust Control' into three lectures:
- lq_permanent_income: the LQ permanent income model
- lq_bewley_complete_markets: cross-section behavior; Bewley and
complete-markets economies
- lq_robust_smoothing: consumption smoothing under model distrust
Lecture files are taken verbatim from Tom's reference copies, which are
byte-identical to branch pr-931. quant-econ.bib needs no update (the
branch bib is already identical to main).
Supersedes PR #942 (branch pr-931), which conflicted with main and
carried stale pre-review versions of kalman_filter_var.md and
robust_permanent_income.md from before the #931 merge.

* Fix duplicate equation labels and stationary-distribution wording
Address Copilot review and the CI build failure on #943:
- Rename eq:pi-endowment -> eq:rs-endowment and eq:pi-crep -> eq:rs-crep
in lq_robust_smoothing.md; both labels were also defined in
lq_bewley_complete_markets.md, and the duplicate-label warnings failed
the jupyter-book build (warnings are errors).
- Reword the Bewley initial-condition passage in
lq_bewley_complete_markets.md: the unit-root permanent component has
no stationary distribution, so describe the actual simulation draws
(z1 ~ N(0,1); transitory z2 from its stationary distribution).
