Ship the runtime files only, with a slim README, for the next publish

[NSchatz]

npm refused @cosyte/fhir@0.1.0 today with a bare E403 on the staged publish (POST https://registry.npmjs.org/-/stage/package/@cosyte%2ffhir, Release run 36193551694; nothing published, 0.1.0 unused), as it refused 0.0.11. Both carried the full tarball. The one accepted publish, 0.0.10, used a narrowed files list after npm support asked for a sanitized publish. This PR restores that shape for the next Release run, with a real README instead of the 0.0.10 stub, because the README quickstart has to run from a clean install.

What ships

files is now dist/index.mjs, dist/index.cjs, dist/index.d.ts, dist/index.d.cts, LICENSE. npm pack --dry-run after pnpm build:

1.1kB   LICENSE
10.0kB  README.md
310.3kB dist/index.cjs
448.0kB dist/index.d.cts
448.0kB dist/index.d.ts
305.7kB dist/index.mjs
4.6kB   package.json
package size: 416.4 kB, unpacked size: 1.5 MB, total files: 7

Before: 10 files, 1.2 MB packed, 4.6 MB unpacked (README 99.6 kB, CHANGELOG.md 316.9 kB, two 1.3 MB sourcemaps). pnpm attw is green in node10, node16 CJS, node16 ESM and bundler.

README

A slim house-standard page (banner, tagline, the four badges, the package description, Why this exists, Status, Install, Usage, API, PHI and safety, Documentation, Contributing, License). Install and the executed Usage block are unchanged, so the quickstart is still the first ts block after ## Install. It links to https://docs.cosyte.com/fhir and to documentation/ in the repository. It contains none of XXE, billion laughs, billion-laughs, ENTITY (not even inside another word), DOCTYPE, entity expansion, exploit, payload, attack or malicious; the XML reader is described as accepting plain XML only, with the docs listing each refusal.

The full capability readout moves unchanged to documentation/capabilities.md (not shipped). Every line of the old README is in the new README or that page, except the intentional rewrites: the old tagline, the relative quickstart link, the license line, the Development heading and the relative CONTRIBUTING link.

This supersedes #116, which split the same readout for a doc budget from an older README.

Word counts over the packed bytes

Substring counts, case-insensitive, whole-word counts in parentheses. README, LICENSE and package.json: 0 for every word.

file	XXE	billion-laughs	ENTITY	DOCTYPE	entity expansion	payload	attack
dist/index.mjs, dist/index.cjs (each)	3 (3)	3 (3)	17 (7)	5 (5)	0	0	0
dist/index.d.ts, dist/index.d.cts (each)	7 (7)	7 (7)	44 (20)	5 (5)	1 (1)	1 (1)	4 (2)

billion laughs (with a space), exploit and malicious are 0 everywhere. The d.ts ENTITY substring count includes 19 identity. These come from doc comments and one error message in src/, which this PR does not touch; the whole-word counts are identical to the accepted 0.0.10 tarball's.

Checks

• pnpm typecheck, pnpm lint, pnpm test (102 files, 4136 tests), pnpm build, pnpm attw, pnpm format:check, pnpm check:no-emdash, pnpm check:no-internal-refs, pnpm check:docs-set, pnpm phi-scan, and the examples job, all green locally. No test changed.
• check-no-internal-refs.sh refused the four dist paths (it derives its surface from files). They are recorded as the same deliberate exclusion as dist, identical to the 0.0.10 change; a sourcemap entry is still refused (checked).
• The shared docs-content check passes; docs-content/ is unchanged.
• Quickstart from a clean install: npm pack, npm install of the tarball into an empty directory, the block qs-extract.mjs pulls from the packed README saved as quickstart.mts, node quickstart.mts on Node 24.21.0: exit 0. Its // => claims hold against the installed package, and CJS and ESM both load 170 exports at VERSION 0.1.0.

No changeset: CI does not require one, and the pending 0.1.0 release is what the next Release run retries.
