feat(phd-phase1-unify-1-2): rename Flos Aureus strand NN-slug.tex -> fa_NN.tex (34 files)

[gHashTag]

Phase 1 UNIFY · task 1.2 — rename Flos Aureus strand to fa_NN.tex

Closes the rename half of trios#380 Phase 1 UNIFY task 1.2. The Trinity S³AI strand (ch_00..ch_34) is unchanged; this PR only renames the Flos Aureus strand from the unprefixed NN-slug.tex namespace to the manifest-canonical fa_NN.tex namespace.

What changed

Commit 1 — git mv 34 chapters (R == 100% similarity, no body edits):

docs/phd/chapters/00-monad.tex                -> fa_00.tex
docs/phd/chapters/01-golden-egg.tex           -> fa_01.tex
docs/phd/chapters/02-golden-cut.tex           -> fa_02.tex
…
docs/phd/chapters/33-epilogue.tex             -> fa_33.tex

Commit 2 — patch \include{chapters/…} paths in:

• docs/phd/main.tex lines 299–353 — 34 substitutions
• docs/phd/main_ru.tex — 34 substitutions

The two \part{…} headers (Flos Aureus 8-part structure on lines 297–353; Trinity S³AI strand on lines 355–391) are unchanged.

Out of scope (deliberate)

• Body edits. This is a pure rename lane. R3 line-count work, R7 falsification additions, R14 Coq map edits — all stay with their per-chapter authors.
• tools/citetheorem_audit/src/lib.rs test data. The NN-slug.tex strings inside #[cfg(test)] blocks are tempdir-scoped fixtures that never reach docs/phd/chapters/; they will be revisited in task 1.5 cross-reference sweep, not here.
• Trinity S³AI strand (ch_NN.tex). Untouched by this PR — manifest 🌻 GOLDEN SUNFLOWERS — Trinity S³AI / Flos Aureus (UNIFIED v6.2 · 98 ch · 2.53M ch · 2173 thm) #380 reserves that namespace for the Neon ssot.chapters export-target.
• bibliography.bib, assertions/igla_assertions.json, any .v file. Not touched (R6 lane discipline).

R-rules compliance

• R1 Rust/Zig only — no .py/.sh introduced; rename done via git mv from a Python helper that lives in agent workspace, not in the repo.
• R2 One branch per task: feat/phd-phase1-unify-1-2.
• R5 No Admitted flips. No bib edits. No content changes.
• R6 No new free parameters introduced.
• R10 Atomic commits: one for git mv, one for \include patches.

Next dependent tasks (per manifest)

• 1.3 Unified main.tex with Part headers — already substantially in place; this PR validates that path.
• 1.5 Fix all \ref{} / \label{} cross-references for dual numbering — depends on this rename landing first.
