fix(noise): enable @libp2p/noise

[tabcat]

Description

Enables the package imported in #3618:

• monorepo-standard package.json (including sideEffects: false and module-sync export conditions) and tsconfig.json; upstream CI/editor/pnpm scaffolding removed (including pnpm-lock.yaml, which resolves the open dependabot alerts against it)
• protobuf regenerated with the monorepo's protons
• tests, lint, dep-check, doc-check and docs generation on (26 tests passing on node and browsers, 9 passing against go-libp2p daemons); the temporary docs and spell-check exclusions from chore: merge js-libp2p-noise into the monorepo #3618 lifted
• registered with release-please, manifest seeded at the current upstream version 17.0.0 so the first release computes 17.0.1
• package docs and runtime identity renamed to @libp2p/noise, with a "Formerly published as @chainsafe/libp2p-noise" note

No behavior changes: the only source edits are lint-fixed import extensions, the regenerated protobuf and the identity strings.

Part of the noise maintenance migration (#3604).

Notes & open questions

In-repo consumers stay on @chainsafe/libp2p-noise until a follow-up switches them over after the first @libp2p/noise release is published. Remaining @chainsafe/libp2p-noise references across the repo (docs, tables, fixtures) are deliberately deferred to that same follow-up, not an oversight.

Change checklist

• I have performed a self-review of my own code
• I have made corresponding changes to the documentation if necessary (this includes comments as well)
• I have added tests that prove my fix is effective or that my feature works
