feat(core): the data home, the lens texts, and --version naming both

Browse source 
process/ holds the procedure, the five lens texts, the templates and the
skill under process/skill/prepush/. A lens text's sha256 is part of every
reuse key and the texts are part of every prompt, so they carry no SPDX
header; --version prints the charter hashes: 1728bd4c, 148d5c4c,
c7ffef44 and 2b9a5f83 for the four charters.

Home() finds them: CRAFTER_REVIEW_HOME, natively only (a host setting
must not swap the Flatpak's texts for a checkout's), then
<exe>/../share/crafter-review, then the checkout the binary was built in.
Main() hands `__supervise` to the supervisor before anything else, then
decides the sandbox once.
