Build with tsdown instead of tsup

tsup is no longer maintained (its README now points at tsdown). tsdown is
the rolldown-based successor from the same lineage.

- migrate all 25 build configs; published files now use explicit .mjs/.cjs
  extensions, which is what rolldown emits and removes the ambiguity that
  made module-format detection guess wrong
- code splitting cannot be disabled in tsdown, so the self-contained CJS
  bundles (varlock init-server/init-edge) each get their own build. A
  shared chunk in those would emit a require() that cannot resolve where
  they get injected into webpack/turbopack runtimes
- @env-spec/utils now emits declarations, which lets tsdown inline its
  types. varlock's published d.ts has been shipping a broken import of
  @env-spec/utils/type-utils, hidden only by skipLibCheck
- drop keepNames: it was an esbuild-era workaround, and with tsdown it
  leaked a runtime-chunk import into the parser's declaration files.
  Class names survive without it since these builds never minify
- port keepass's esbuild resolver plugin to a rolldown resolveId hook
- infisical patched its bundle by string-replacing 'use strict', which
  tsdown does not emit. Use a real banner instead
- drop two entries that pointed at files which no longer exist; tsup
  ignored them silently, tsdown errors

Also enable publint on every publishable package's build. It fails the build
on real errors (verified), so exports problems surface at build time instead
of after publish.

Fixing what it found:
- varlock's ./test-helpers export pointed at src/test-helpers/plugin-test.ts,
  which is not in `files` and so was never published. It is a real entry point
  now (3.4kB, vitest externalized as an optional peer). Keeping only the
  monorepo `ts-src` condition was not viable: vite does not apply custom
  conditions when resolving a dependency, so plugin tests broke
- repository.url everywhere is a full git+https URL
- @env-spec/parser and @varlock/nextjs-integration declare "type": "commonjs"
  rather than making node sniff it. Their tsdown configs move to .mts, since
  node otherwise loads the .ts config as CJS and tsdown is ESM-only
