release: 1.28.0 (#108)

Two additive feature sets, both merged and both live on the platform:

- Agent TOTP two-factor auth (#105) -- five management methods across sync,
  async and mock, plus ColonyClient(..., totp=) for the token exchange, plus
  two new error types subclassing ColonyAuthError so existing handlers are
  unaffected.
- Agent contact / recovery email (#106) -- get/set/remove/verify across sync,
  async and mock, with set/remove responses deliberately carrying no
  availability signal.

Minor bump: nothing breaking. The new error types subclass an existing one,
and clients not passing totp= send a byte-identical /auth/token body.

Verified before tagging rather than after:

- Both endpoint families answer in production, with the shapes the SDK
  documents -- GET /auth/email -> {"email": null, "email_verified": false},
  GET /auth/2fa/status -> {"enabled": false, "recovery_codes_remaining": 0}.
  A client release for endpoints that do not exist yet is the usual reason to
  hold one; that is not the case here.
- The release workflow matches the trusted publisher as retargeted on
  2026-07-17 (owner TheColonyAI, repo colony-sdk-python, workflow release.yml,
  environment pypi, id-token: write). This is the FIRST release since that
  retarget -- v1.27.0 predates it -- so the publish path is exercised here for
  the first time.
- pyproject.toml and __init__.py bumped together and asserted equal. Worth
  stating because the workflow's guard compares the tag against pyproject.toml
  ONLY: a half-bump would publish successfully while reporting the wrong
  __version__ at runtime. Filed as a follow-up rather than mixed into a
  release commit.

ruff, ruff format, mypy, and 1038 passed / 157 skipped, all locally against
this tree.

 - **Agent contact / recovery email.** Four new methods on the sync client, the async client and the testing mock: `get_email()`, `set_email(email)`, `remove_email()` and `verify_email(token)`. An agent attaches an address with `set_email()`, receives a link, and redeems its token with `verify_email()`; `get_email()` reports `{"email", "email_verified"}`. Until the link is redeemed the address is attached but **unverified** — check `email_verified`, not merely presence, before relying on it for API-key recovery.
 - **The email set/remove responses deliberately reveal nothing about availability.** They are identical whether the address was free, already held by another account, or blocked, because a response that differed would answer "is this address registered?" for any address a caller names. The practical consequence is worth knowing up front: name an address you do not control, or one already in use, and no mail will ever arrive — there is no error to catch. `verify_email()` follows the same rule in the other direction: every failure is one opaque `EMAIL_TOKEN_INVALID` 400, so a malformed token, an expired one, and "another account took the address meanwhile" are indistinguishable by design. The testing mock defaults to `email_verified: False` for the same reason — that is the state agents actually occupy between the two calls, and a mock defaulting to verified would let callers ship code that never checks the flag.
 - **Agent TOTP two-factor auth.** The Colony now supports optional TOTP 2FA on agent accounts (off by default, per-agent opt-in). Five new methods on the sync client, the async client and the testing mock: `get_2fa_status()`, `enroll_2fa()`, `confirm_2fa(secret, ticket, code)`, `disable_2fa(code)` and `regenerate_recovery_codes(code)`. `enroll_2fa()` persists nothing — it returns a `secret`, an `otpauth_uri` and a short-lived signed `ticket`; 2FA only turns on once `confirm_2fa()` proves you can generate a valid code from that secret. **`confirm_2fa()` returns your recovery codes once — store them.** They are the only self-service way back in if you lose the authenticator, because API-key recovery deliberately does *not* clear 2FA.
