docs(readme): promote Claude orientation to a top-level section

The seeding mechanism was previously buried as a sub-subsection inside
Development flow. Promote it to its own ## Claude orientation section
with a concrete value-prop: a Claude session in
~/dev/lnbits/extensions/<ext>/templates/ inherits the Vue/Quasar UMD
"no self-closing tags" rule from the per-project CLAUDE.md, so the
model writes the explicit-close form instead of the silently-broken
self-close that would corrupt LNbits template nesting.

Lists the other gotchas the seeding surfaces (settings precedence,
auth decorators, upstream PR target, CLINK ↔ LNbits scope) so a
reader scanning the README sees what they get without enabling the
option first.

Development flow's day-to-day subsection now points down to the new
section instead of explaining the wiring inline; the wiring snippet
moved to the Claude orientation section where it sits next to the
value-prop.

+## Claude orientation
+
+For workflows that use [Claude Code](https://docs.anthropic.com/en/docs/claude-code),
+lnbits-sensei ships curated workspace orientation that gets symlinked
+into `~/dev/` so AI-assisted work picks up lnbits-specific gotchas
+without anyone copying files around or re-explaining them in every
+session.
+
+**Concrete example.** A Claude session iterating in
+`~/dev/lnbits/extensions/<my-ext>/templates/` automatically inherits
+the per-project `CLAUDE.md` from `~/dev/lnbits/`, which carries the
+**Vue/Quasar UMD "no self-closing tags"** rule. Without that seed,
+Claude would happily emit:
+
+```html
+<q-input v-model="amount" label="Amount" />
+```
+
+Correct in any Vue SFC repo, **silently broken** under LNbits's UMD
+load model — the browser's HTML parser doesn't honor self-close on
+non-void elements, the close tag gets implied at the wrong place, and
+nesting corrupts. With the seed loaded, the model writes:
+
+```html
+<q-input v-model="amount" label="Amount"></q-input>
+```
+
+— the form that actually works. Same story for every other gotcha
+the per-project CLAUDE.md surfaces:
+
+- **Settings precedence** — editing `.env` post-first-boot is a no-op
+  for editable fields. AI knows to check `system_settings` rows or
+  Admin UI, not chase env-var edits.
+- **Auth decorators** — `require_admin_key` (per-wallet write) ≠
+  `check_admin` (instance admin). Easy to misuse.
+- **Upstream PR target** — `lnbits/lnbits` accepts PRs against `dev`,
+  not `main`. Lowercase conventional-commit titles.
+- **CLINK ↔ LNbits scope** — `ndebit` / `noffer` semantics live in
+  Lightning.Pub, not LNbits. Don't propose CLINK shims for LNbits.
+
+The full set lives in `docs/`; the seeded `CLAUDE.md` files are tight
+summaries with pointers back.
+
+### How it works
+
+Files in this repo's `files/` directory are symlinked to your `~/dev/`
+paths via home-manager's `mkOutOfStoreSymlink` — edits in your
+checkout take effect on the next Claude session, no rebuild.
+
+- `files/lnbits-CLAUDE.md` → `~/dev/lnbits/CLAUDE.md` (per-project)
+- `files/dev-CLAUDE.md` → `~/dev/CLAUDE.md` (workspace, opt-in)
+
+### Wiring
+
+In your `settings.nix`:
+
+```nix
+devEnv = {
+  enable = true;
+  scaffoldPath = "/home/<you>/dev/lnbits-sensei";   # absolute path
+  claude = {
+    enable = true;                # ~/dev/lnbits/CLAUDE.md
+    workspaceOrientation = false; # also ~/dev/CLAUDE.md (opt-in;
+                                  # clobbers any existing one)
+  };
+};
+```
+
+If you don't use Claude Code, leave both off — the same content is in
+`docs/` for human reading. The seeding is purely an optional layer on
+top of the human-facing docs, not a replacement for them.
