feat(cli)!: subject-based command tree (tea-style) + global --output flag

BREAKING:
- Flat oo verb-noun layout replaced with subject → verb, mirroring the
  gitea `tea` CLI. Every subject is one file in cmd/oo/:

    oo calendar       list | events | add | delete
    oo projects       list | get | milestones | create | update | delete
    oo tasks          list | get | create | update | delete | subtask add
    oo users          list | self                  (alias: oo whoami)
    oo contacts       list | get | delete | info-add
    oo persons        list | create | delete
    oo companies      list | create | delete
    oo opportunities  list | get | create | delete | stages | member-add
    oo cases          list | create | delete | member-add
    oo crm-tasks      list | create | delete | categories
    oo applications   sync

- Global `--output/-o table|json` flag on the root command; every list uses
  a single printTable helper that flattens nested bidCurrency → abbreviation
  for readability, truncates long cells, and dumps verbatim in JSON mode.

Library additions surfaced in the CLI:
- oo users / oo whoami via SelfUserID + GetUsers.
- oo projects full CRUD via Create/Update/Delete/GetProjectByID/Milestones.
- oo crm-tasks and oo cases via ListCRMTasks/CreateCRMTask/DeleteCRMTask/
  ListTaskCategories/ListCases/CreateCase/DeleteCase/AddCaseMember.
- oo contacts info-add via AddContactInfo.
- oo opportunities stages/member-add via ListDealStages/AddOpportunityMember.

Internal:
- cmd/oo/common.go — rootCmd, newOO (uses AuthenticateContext), printTable,
  printObject, fmtCell, deref* helpers.
- cmd/oo/crm.go deleted; content split into contacts.go, opportunities.go,
  cases.go, crm_tasks.go for locality.

Docs:
- README: new subject→verb table + migration note.
- AGENTS.md: CLI section rewritten; new rule enforcing subject→verb and
  printTable/printObject routing.
- CHANGELOG: 0.5.0 entry with full old→new mapping.
