ZdenekSrotyr 1563b05f2e refactor(cli): hard-cutover env vars + config dir to AGNES_*
Task 0.5 of clean-analyst-bootstrap. Greenfield rewrite — no fallback,
no aliases. Existing dev environments lose their cached PAT and must
re-authenticate.

Env var renames (hard cutover):
- DA_CONFIG_DIR    -> AGNES_CONFIG_DIR
- DA_SERVER        -> AGNES_SERVER
- DA_SERVER_URL    -> AGNES_SERVER_URL  (test-only stale ref, not in spec)
- DA_NO_UPDATE_CHECK -> AGNES_NO_UPDATE_CHECK
- DA_LOCAL_DIR     -> AGNES_LOCAL_DIR
- DA_TOKEN         -> AGNES_TOKEN
- DA_STREAM_RETRIES -> AGNES_STREAM_RETRIES

Config dir rename: ~/.config/da/ -> ~/.config/agnes/ (across code,
comments, docstrings, error messages, install templates, dev scripts).

Stale `da X` references in CLI source (and adjacent app/, tests/):
swept docstrings, comments, help text, and error messages where the
verb survives the rewrite (init, pull, push, catalog, status, diagnose,
auth, admin, skills, query, schema, describe, explore, disk-info,
snapshot, login, logout, whoami, server, setup) and replaced `da X`
with `agnes X`. Intentionally kept `da sync`, `da fetch`, `da analyst`,
`da metrics` — those verbs are removed in later tasks; the legacy
strings will be detected by `_LEGACY_STRINGS` (added in Task 2).

Test fixes:
- TestCLIVersion now asserts output starts with `agnes ` (was `da `).

Test results: 2675 passed, 25 skipped (full pytest run, excluding 9
pre-existing test_db.py / test_user_management.py / test_e2e_extract.py
/ test_cli_binary_rename.py failures unrelated to this rename).
