fix: quiet logs progress output (#1472) (thanks @czekaj)

The progress spinner was being shown for each gateway RPC call during
log tailing, causing repeated spinner frames (◇ │) to appear every
polling interval.

Add a `progress` option to `callGatewayFromCli` and disable the spinner
during follow mode polling to keep output clean.

-# Transcript Hygiene (Provider Fixups)
-
-This document describes **provider-specific fixes** applied to transcripts before a run
-(building model context). These are **in-memory** adjustments used to satisfy strict
-provider requirements. They do **not** rewrite the stored JSONL transcript on disk.
-
-Scope includes:
-- Tool call id sanitization
-- Tool result pairing repair
-- Turn validation / ordering
-- Thought signature cleanup
-- Image payload sanitization
-
-If you need transcript storage details, see:
-- [/reference/session-management-compaction](/reference/session-management-compaction)
-
----
-
-## Where this runs
-
-All transcript hygiene is centralized in the embedded runner:
-- Policy selection: `src/agents/transcript-policy.ts`
-- Sanitization/repair application: `sanitizeSessionHistory` in `src/agents/pi-embedded-runner/google.ts`
-
-The policy uses `provider`, `modelApi`, and `modelId` to decide what to apply.
-
----
-
-## Global rule: image sanitization
-
-Image payloads are always sanitized to prevent provider-side rejection due to size
-limits (downscale/recompress oversized base64 images).
-
-Implementation:
-- `sanitizeSessionMessagesImages` in `src/agents/pi-embedded-helpers/images.ts`
-- `sanitizeContentBlocksImages` in `src/agents/tool-images.ts`
-
----
-
-## Provider matrix (current behavior)
-
-**OpenAI / OpenAI Codex**
-- Image sanitization only.
-- No tool call id sanitization.
-- No tool result pairing repair.
-- No turn validation or reordering.
-- No synthetic tool results.
-- No thought signature stripping.
-
-**Google (Generative AI / Gemini CLI / Antigravity)**
-- Tool call id sanitization: strict alphanumeric.
-- Tool result pairing repair and synthetic tool results.
-- Turn validation (Gemini-style turn alternation).
-- Google turn ordering fixup (prepend a tiny user bootstrap if history starts with assistant).
-- Antigravity Claude: normalize thinking signatures; drop unsigned thinking blocks.
-
-**Anthropic / Minimax (Anthropic-compatible)**
-- Tool result pairing repair and synthetic tool results.
-- Turn validation (merge consecutive user turns to satisfy strict alternation).
-
-**Mistral (including model-id based detection)**
-- Tool call id sanitization: strict9 (alphanumeric length 9).
-
-**OpenRouter Gemini**
-- Thought signature cleanup: strip non-base64 `thought_signature` values (keep base64).
-
-**Everything else**
-- Image sanitization only.
-
----
-
-## Historical behavior (pre-2026.1.22)
-
-Before the 2026.1.22 release, Clawdbot applied multiple layers of transcript hygiene:
-
-- A **transcript-sanitize extension** ran on every context build and could:
-  - Repair tool use/result pairing.
-  - Sanitize tool call ids (including a non-strict mode that preserved `_`/`-`).
-- The runner also performed provider-specific sanitization, which duplicated work.
-- Additional mutations occurred outside the provider policy, including:
-  - Stripping `<final>` tags from assistant text before persistence.
-  - Dropping empty assistant error turns.
-  - Trimming assistant content after tool calls.
-
-This complexity caused cross-provider regressions (notably `openai-responses`
-`call_id|fc_id` pairing). The 2026.1.22 cleanup removed the extension, centralized
-logic in the runner, and made OpenAI **no-touch** beyond image sanitization.
