feat(ms-ai-architect): C2.1 lib/user-data resolver + ambient org-injeksjon + C1 config bakoverkompat (TDD) [skip-docs]

Bæreren i C2 onboarding-redesign (#26). TDD: test FØR kode.

- lib/user-data.mjs (NY, ren, SKRIVER ALDRI; kun node:os/path):
  resolveUserDataDir/resolveOrgDir/resolveConfigPath peker ~/.claude/ms-ai-architect/
  (uavhengig av pluginRoot -> overlever reinstall, K2). CONFIG_FILENAME delt med C1
  (en sannhetskilde). buildOrgSummary: deterministisk, lengde-kappet H2-ekstraksjon.
- detection-schedule.mjs: loadScheduleConfig(pluginRoot, home=homedir()) leser
  bruker-sti FORST, fallback plugin-rot. Lokal CONFIG_FILENAME -> importeres fra resolver.
  Alle 3 kallere bruker ett-arg-kall (uendret oppforsel).
- session-start-context.mjs: injiserer buildOrgSummary ambient (K1) som egen
  Virksomhetskontekst-blokk; status-nudge beholdt nar org tom.

Verifisert: user-data 16/16 · detection-schedule 23/23 · test-hooks 10/10 ·
kb-update 191 · kb-eval 100 · validate PASSED.
