Krzysztof kuhy Rudnicki 17a2c62f26 Automate CLAUDE.md's structural rules, then cut it to 189 lines
CLAUDE.md was 1101 lines and loaded into every session in this repo. Three
passes, in order: automate what a gate can check, rewrite what is left as
instructions rather than rationale, extract what still does not fit.

Automated. Five prohibitions were enforced by nothing but a paragraph asking a
future reader not to do something; they are now repo_invariants_test.dart:

  - no app/linux/ (a GTK embedder target manages ~20fps at 4K)
  - dart:io only in *_io.dart seams and lib/desktop/ -- this one is why the
    test exists at all, since dart:io does not fail a web *compile*. It throws
    at runtime, so a bad import is a blank white window that the widget tests
    happily pass through.
  - no meal builder / repeat-last-meal / reward prompt
  - no image_picker, no CAMERA permission
  - wrapper port 8732 and the diet-guard-desktop Chrome profile, both pinned
    because IndexedDB is keyed by origin and moving either hides the whole
    local food log

Each guard was canary-tested by breaking the invariant and confirming the
suite goes red -- a guard that cannot fail is decoration.

Rules whose behaviour was already covered (budget epoch seeding, sync merge,
food bank) shrink to a pointer at the test that owns them.

Where a rule's entire value was its rationale ("the removal is the feature"),
the why moved into the name and reason string of the gate that now enforces
it, so it lives somewhere executable instead of somewhere quotable.

Extracted. The vendored flutter/flutter rules were 789 of the 1101 lines --
72% of the file, none of it about this repo. Split into five docs/ topic files
under the cap and linked. Verified content-complete: 664 non-blank lines in,
664 out, zero missing.

Python 692 tests / 100% coverage unchanged; Flutter 548 -> 555 (+7 new).
