spec(ifc-fides): address review; reframe action-metadata for SEP-2061 closure

Browse source 
ifc-fides (review by @JoannaaKL):
- confidentiality is public/private only on the wire; drop the reader-list
  (logins aren't uniform across servers, are themselves access-restricted,
  and reader sets can be huge)
- add Reader-set resolution section: two private markers aren't equal, the
  confidentiality join is the intersection and isn't computable from opaque
  wire markers, so hosts resolve to concrete reader sets at decision time
- integrity join is total/wire-computable; confidentiality join is not
- emitter MUST classify per resource, not per repository (public repos serve
  non-world-readable sub-resources), making github-mcp-server a real proof point

action-metadata / docs:
- SEP-2061 closed 2026-06-13 in favour of this extension; this draft is now the
  canonical home. Updated action-metadata.mdx, README, sep-disposition,
  related-work, and intent-comment status accordingly.

### SEP-2061 — Action Security Metadata
**Proposed:** becomes the [`action-metadata`](../specification/draft/action-metadata.mdx)
extension. SEP-2061 is by [@rreichel3](https://github.com/rreichel3), who is
also an IG co-facilitator and SEP-1913 co-author, so this is a fold-in, not a
collision. Disposition mirrors 1913 option (A): keep the thread as the field-
semantics discussion, add a pointer comment linking it to the
`action-metadata` extension, refactor to Extensions Track when ready.
**Disposition:** **closed 2026-06-13** in favour of the
[`action-metadata`](../specification/draft/action-metadata.mdx) extension.
SEP-2061 is by [@rreichel3](https://github.com/rreichel3), who is also an IG
co-facilitator and SEP-1913 co-author, so this was a fold-in, not a collision.
[@localden](https://github.com/localden) closed the PR (no active sponsor) after
agreeing the extension is the right home; the extension now carries the field
semantics forward, with SEP-2061 preserved as the origin and credit.
