Drop foundry.toml release metadata: version intent lives in next-v tags (rainix#335)

[thedavidmeister]

Deletes the foundry.toml release-metadata section per rainlanguage/rainix#335. Since rainlanguage/rainix#336 merged, rainix-autopublish derives the publish version from the Soldeer registry plus next-v* git tags; the section is never read, and the autopublish content gate excludes it (including its attached comment block) from the content hash, so this deletion is content-neutral: it cannot mint a spurious release and changes no behavior. Also rewrites the README Publish section, which still described the pre-#336 flow (version bump committed back to main; [package] version as next unpublished version).

QA

• Discriminating tests: n/a - config-metadata deletion; nothing reads the section since rainix#336 (local nix develop -c reuse lint green; forge soldeer install + forge test: 391 passed, 0 failed)
• Mutations applied: n/a - no code changed
• Oracle: rainix#336 gate semantics (section excluded from content hash; version from registry + next-v tags)
• Category check: issue asks removal of release metadata from consumers; covered exactly for this repo

Walkthrough

Publishing no longer commits a package-version bump to main. The version derives from the latest Soldeer version and merged next-v<x.y.z> tags. The foundry.toml release metadata block was removed.

Addressed in 507762f: README now states the tag is read only when a push to main runs the workflow — it must already be merged into the pushed head; a tag-only push publishes nothing.
