leonarski_fandClaude Opus 4.8 0220c6376d cmake: fetch libtiff and FFTW instead of relying on system libs
Both are leaf deps (JFJochPreview / JFJochIndexing) that only our own code
looks for, so building them ourselves removes the system-package lottery and
gives a reproducible, statically-linked build on every platform.

- libtiff: FetchContent, library only (jbig/zstd/lzma/jpeg/old-jpeg/tools/
  tests off). The C++ binding (TIFF::CXX / libtiffxx) is packaged
  inconsistently across distros -- missing on Rocky 9 -- and absent on
  Windows, so find_package(TIFF COMPONENTS CXX) was unreliable; that call is
  removed and JFJochPreview links the tiff/tiffxx targets directly. GitHub
  mirror because upstream (gitlab) is unreachable from some restricted hosts.
- FFTW: FetchContent single precision (ENABLE_FLOAT) from the release tarball
  -- the git repo ships no pre-generated codelets (needs OCaml genfft). It's
  now always available, so the CPU FFT indexer is always built and
  JFJOCH_USE_FFTW always defined; the "FFTW disabled" path is gone. Static
  (libfftw3f.a) via the global BUILD_SHARED_LIBS OFF.

Verified on Linux: jfjoch_viewer builds and links libfftw3f.a + libtiff*.a,
all static.
