chore(salvage): strip duplicated/merge-corrupted blocks from PR #17664

Removes drive-by duplication that accumulated during the contributor
branch's multiple rebases. All runtime-benign (dict last-wins,
redefinition last-wins) but left dead source that would confuse
reviewers and maintainers.

Surgical in-place de-duplication (kept PR's intentional additions,
removed only the doubled copy):

* hermes_cli/auth.py: duplicate "gmi" + "azure-foundry" ProviderConfig
* hermes_cli/models.py: duplicate "gmi" entry in _PROVIDER_MODELS
* hermes_cli/config.py: duplicate NOTION/LINEAR/AIRTABLE/TENOR skill env
  block + duplicate get_custom_provider_context_length definition
* hermes_cli/gateway.py: duplicate _setup_yuanbao
* gateway/platforms/base.py: duplicate is_host_excluded_by_no_proxy
* gateway/platforms/telegram.py: duplicate delete_message
* gateway/stream_consumer.py: duplicate _should_send_fresh_final and
  _try_fresh_final
* gateway/run.py: duplicate _parse_reasoning_command_args /
  _resolve_session_reasoning_config / _set_session_reasoning_override,
  duplicate "Drain silently when interrupted" interrupt check
* run_agent.py: duplicate HERMES_AGENT_HELP_GUIDANCE append, duplicate
  codex_message_items capture, duplicate custom_providers resolution
* tools/approval.py: duplicate HARDLINE_PATTERNS section and duplicate
  hardline call in check_dangerous_command
* tools/mcp_tool.py: duplicate _orphan_stdio_pids module-level decl
* cron/scheduler.py: duplicate "not configured/enabled" check — kept
  the new early-rejection, removed the stale late-path copy

Full-file resets to origin/main (all PR additions were duplicates of
