Purge stale TS/VS Code-era docs; finish .adoc migration where unambiguous

Several docs still described the long-dead TypeScript VS Code extension (npm,
Jest, Babel, "JS→ReScript patterns") — two host-generations out of date and
actively misleading.

Rewritten to current reality (correspondence engine; Deno + cartridges runtime;
Idris2 ABI + Zig FFI + AffineScript host spine; cartridge authoring as the
contribution model; no-shame voice):
- docs/RSR_COMPLIANCE.md -> docs/RSR_COMPLIANCE.adoc (accurate + honest; neutral
  licensing section that defers to LICENSE)
- docs/TPCF.md -> docs/TPCF.adoc (perimeter model reframed for cartridges)
- CONTRIBUTING.md rewritten in place (kept .md — GitHub-required file)

Removed (superseded by a clean .adoc twin):
- MAINTAINERS.md (MAINTAINERS.adoc is canonical)

References repointed: README badges + links, CODE_OF_CONDUCT.md, SECURITY.md,
.github/workflows/ci.yml + .gitlab-ci.yml doc checks, Justfile validate-docs.
deno fmt/lint/test/build all green; no dangling links remain.

Out of scope (flagged, deliberately untouched):
- Licence-label drift (config.ncl "MIT OR Palimpsest", README "Palimpsest
  License (MPL-2.0)", LICENSE-MIT/PALIMPSEST vs the MPL-2.0 classification) —
  owner-only per the licence guardrail.
- The CONTRIBUTING.md / CHANGELOG.md .md-vs-.adoc choice for GitHub-required files.
