Apply sanitizeChatHistoryMessages before pagination in the bounded SSE
history refresh path, consistent with the unbounded path. Initialize
rawTranscriptSeq from the raw transcript's last __openclaw.seq value
instead of the sanitized history length, preventing seq drift when
sanitization drops messages.

- Bounded/cursor SSE refresh path now sanitizes through
sanitizeChatHistoryMessages before paginating, matching the
unbounded path and initial history load.
- Export DEFAULT_CHAT_HISTORY_TEXT_MAX_CHARS from chat.ts and
import in sessions-history-http.ts instead of duplicating.
The createStreamFn callback hardcoded config.models.providers.ollama.baseUrl,
ignoring the actual provider ID from the context. When multiple Ollama providers
are configured on different ports (e.g. ollama on 11434, ollama2 on 11435), all
requests routed to the first provider's port.
Export resolveConfiguredOllamaProviderConfig from stream.ts and use it with the
ctx.provider parameter to dynamically look up the correct baseUrl per provider.
Closes#61678
- Use `sonnet-4` substring match instead of enumerating `sonnet-4-5`,
`sonnet-4-6` explicitly. This is safe because legacy `claude-3-5-sonnet`
does not contain `sonnet-4`, and it future-proofs for sonnet-4-7+.
- Export `shouldPreserveThinkingBlocks` from provider-replay-helpers.ts
and import it in transcript-policy.ts instead of duplicating the logic.
Addresses review feedback from Greptile.
The shared-helper tests still expected dropThinkingBlocks: true for
claude-sonnet-4-6. Updated to match the new behavior where Sonnet 4.6
preserves thinking blocks.
Claude Opus 4.5+ and Sonnet 4.5+ preserve thinking blocks in model context
by default. Dropping them from prior turns (as was correct for Sonnet 3.7)
breaks Anthropic's prefix-based prompt cache matching, causing cache misses
after every thinking turn.
This change conditions dropThinkingBlocks on the model version:
- Preserve (no drop) for: opus-4.x, sonnet-4.5+, haiku-4.x, and future models
- Drop for: claude-3-7-sonnet and earlier
