Cut 2.3.0

[HarryCordewener]

Release preparation, steps 1 and 2 of docs/releasing.md.

• ## Unreleased becomes ## 2.3.0 — 2026-09-22, with the clear-across-a-delegated-layer fix folded into the nesting entry it belongs to.
• PublicAPI.Unshipped.txt promoted to PublicAPI.Shipped.txt in all five packages: 202 members in the core, 6 in Ansi, 3 in Mxp, 2 in Pueblo, none in Html. From here the analyzer treats a removal or a signature change as a build error.

Verified: 644/644 tests, and all five packages pack (core, Ansi and Html against the 2.2.0 baseline; Mxp and Pueblo have none yet, which is their first release).

Version judgement. 2.3.0 rather than 3.0.0: every API change is additive, and the behaviour changes that could reach an existing consumer are narrow. Worth your eye before tagging:

• HTML, Pueblo, MXP and BBCode now render a layer from another package nested inside styling inside that styling, so anyone pinning exact rendered strings sees different output. The portal's own CSS does not care.
• MarkupRegistry.With(IMarkupCodec) now throws for a codec claiming a kind core writes itself — only reachable by a consumer who happened to pick sound, image, pane and the like.
• MarkupText.Wrap now throws for a point over non-carrier text, which nothing released could build: points arrive in this release.

If you would rather treat the rendering change as breaking, say so and I will redo this as 3.0.0.
