Name the renamed collection in fly_footprint docs - #46

Memory audit, second pass. 2 entries plus the index; 0 migrations — both were
dispositioned in the pass an hour earlier and nothing has accumulated since.

| Action | Count | Detail |
|---|---|---|
| migrate | 0 | nothing new since the previous audit |
| skip — canonical doc exists | 1 | the fly#38 answer, in `inst/notes/georeferencing.md` |
| keep in memory — user | 1 | `concurrent-soul-sessions` |
| keep in memory — infrastructure identity | 1 | `georef-ground-truth`, already reduced to identity only |
| update CLAUDE.md project section | 1 | this commit |

The one finding is a stale-state check, not a memory migration:
`data-raw/georef_calibrate-corner_mapping.R` was not named in Architecture while its
siblings `make_camera_formats.R` and `make_testdata.R` are, and it is the script that
reproduces the three measurements the note describes.

Two probes were wrong before they were right, both worth recording:

- Comparing `ls R/` against the Architecture list reported that CLAUDE.md names NONE of
  the 11 R files. It names three. The `ls` output carried ANSI colour codes from a shell
  alias — the trap `code-check.md` documents — so every comparison mismatched. The tell
  was that the answer was obviously false.
- The rewrite used `mapfile`, which macOS bash 3.2 does not have, and reported 0 files.

Re-run with `find` and a plain loop, with controls asserting a known-present and a
known-absent filename: 3 of 11 named, by design — Architecture is a curated list of where
the non-obvious things live, not a manifest.

Also checked and clean: no file outside the soul appendix and the #9 PWF archive names the
old `stac-dem-bc` collection after PR #46's rename; `DESCRIPTION` 0.7.1 matches tag v0.7.1.
The appendix hits are the *repo* name `stac_dem_bc`, which did not change, and the archive
is history rather than drift.
