thePR0M3TH3AN 2beb7a7bb5 feat: adapter contract, commerce proof-of-fit, and reusability docs
Proves the engine did not stay video-specific during extraction.

- application adapter contract in core (createApplicationAdapter,
  evaluateObject, collectTargets): an object names the targets that govern it
  and the strictest verdict reaching any of them wins, so denying a seller
  takes their whole catalogue down with no cascade logic in the application
- examples/commerce: a marketplace on the public API covering all ten
  proof-of-fit behaviors the plan requires, including that no core change was
  needed. One product, one snapshot, four surfaces, four different verdicts.
- README, integration guide, per-example README, CHANGELOG, four ADRs, and
  GPL-3.0-or-later LICENSE (the license was listed in Phase 1 but missing)
- checkpoints rewritten to reflect actual state and to say plainly which
  migration-plan phases belong to the consumer repos rather than here

Fixes a real gap found by the proof-of-fit: composeDecisions kept only the
first decision's evidence, so an object governed by several targets lost the
evidence that drove its verdict. Evidence now merges — counts summed,
contributor lists unioned, flags or-ed.

556 tests; lint, typecheck, and per-package type build clean.

# ADR 0004 — The core is hex-only
**Status:** accepted
## Context
Administrative lists in the wild contain both hex pubkeys and `npub` strings,
and the reference implementation normalized them everywhere it touched them.
Doing the same in the core would mean bech32 decoding in a package that is
meant to have no dependencies and no encoding opinions.
## Decision
`@nostr-governance/core` accepts 64-character hex only. Decoding lives in
`@nostr-governance/nostr` (`normalizePubkeyInput`, `normalizeEventIdInput`),
and codecs normalize at ingest, so the core only ever sees hex.
## Consequences
The core stays dependency-free and runs unchanged in Node and the browser.
The trade-off is a real footgun: `normalizePubkey` returns `""` for a valid
`npub` rather than throwing. Callers that hand user input straight to the core
will silently get nothing. Anything accepting operator or user input must
normalize through the codec package first — this is called out in the
integration guide.
