Manoj Bajaj d6958c8434 refactor!: unify Identity and Profile; remove profile management layer ...

Profile is now a pure credential namespace scoped by the Identity handle,
not an independently managed entity. The two were always 1:1 but modelled
as separate concepts; this commit makes that explicit.

Key changes:
- Add `active_identity` to GlobalConfig; `ensure_local_identity` reads it
  and errors hard if the configured handle is missing on disk (no silent
  re-creation)
- `authsome init` writes `active_identity` to config after registration
- Collapse `registered: bool` + `registration_status: str` on
  IdentityMetadata into a single `registered: bool`; add `mark_registered()`
- Remove vestigial `Identity` dataclass, `DEFAULT_IDENTITY`, `current()`
- Remove `name`, `description`, `owner_email` from IdentityMetadata (deferred
  to hosted version)
- Remove `ProfileMetadata`, `ProfileNotFoundError`, `create_profile`,
  `list_profiles`, `get_profile`, `set_default_profile`, `default_profile`
  shim in save_config — profile is a side-effect of identity registration
- Add hard-error test for missing configured identity
- Update UBIQUITOUS_LANGUAGE.md, AGENTS.md architecture section, and
  ADR 0002 to reflect current code (fix stale AuthsomeContext, AuthClient,
  config.json path, ProfileMetadata references)
