refactor(backend/copilot): make helper fns public to remove private-import Pyright warnings

_process_cli_restore → process_cli_restore
_read_cli_session_from_disk → read_cli_session_from_disk

Both functions are directly tested in sdk/transcript_test.py, which requires
importing them by name. Importing private (_-prefixed) symbols from outside
the defining module triggers reportAttributeAccessIssue in Pyright.  Making
them public removes the editor warnings without changing behaviour.

+"""Tests for transcript context coverage when switching between fast and SDK modes.
+
+When a user switches modes mid-session the transcript must bridge the gap so
+neither the baseline nor the SDK service loses context from turns produced by
+the other mode.
+
+Cross-mode transcript flow
+==========================
+
+Both ``baseline/service.py`` (fast mode) and ``sdk/service.py`` (extended_thinking
+mode) read and write the same CLI session store via
+``backend.copilot.transcript.upload_transcript`` /
+``download_transcript``.
+
+Fast → SDK switch
+-----------------
+On the first SDK turn after N baseline turns:
+  • ``use_resume=False``  — no CLI session exists from baseline mode.
+  • ``transcript_msg_count > 0`` — the baseline transcript is downloaded and
+    validated successfully.
+  • ``_build_query_message`` must inject the FULL prior session (not just a
+    "gap" since the transcript end) because the CLI has zero context without
+    ``--resume``.
+  • After our fix, ``session_id`` IS set, so the CLI writes a session file
+    on this turn → ``--resume`` works on T2+.
+
+SDK → Fast switch
+-----------------
+On the first baseline turn after N SDK turns:
+  • The baseline service downloads the SDK-written transcript.
+  • ``_load_prior_transcript`` loads and validates it normally — the JSONL
+    format is identical regardless of which mode wrote it.
+  • ``transcript_covers_prefix=True`` → baseline sends ONLY new messages in
+    its LLM payload (no double-counting of SDK history).
+
+Scenario table (SDK _build_query_message)
+==========================================
+
+| # | Scenario                       | use_resume | tmc | Expected query message          |
+|---|--------------------------------|------------|-----|---------------------------------|
+| P | Fast→SDK T1                    | False      | 4   | full session injected           |
+| Q | Fast→SDK T2+ (after fix)       | True       | 6   | bare message only (--resume ok) |

+"""Tests for the pre-create assistant message logic that prevents

+
+Reproduces the bug where:
+  1. Tool result is saved by intermediate flush → last_role=tool
+  2. SDK generates a text response
+  3. GeneratorExit at StreamStartStep yield (client disconnect)
+  4. _dispatch_response(StreamTextDelta) is never called
+  5. Session saved with last_role=tool instead of last_role=assistant
+
+The fix: before yielding any events, pre-create the assistant message in
+ctx.session.messages when has_tool_results=True and a StreamTextDelta is
+present in adapter_responses.  This test verifies the resulting accumulator
+state allows correct content accumulation by _dispatch_response.

+
+    This is the shared context primitive used by both the SDK path
+    (``use_resume=False`` → ``<conversation_history>`` injection) and the
+    baseline path (OpenAI messages array).
+
+    How it works:
+
+    - When a transcript exists, ``TranscriptBuilder.load_previous`` preserves
+      ``isCompactSummary=True`` compaction entries, so the returned messages
+      mirror the compacted context the CLI would see via ``--resume``.
+    - The gap (DB messages after the transcript watermark) is always small in
+      normal operation; it only grows during mode switches or when an upload
+      was missed.
+    - Falls back to full DB messages when no transcript exists (first turn,
+      upload failure, or GCS unavailable).
+    - Returns *prior* messages only (excluding the current user turn at
+      ``session_messages[-1]``).  Callers that need the current turn append
+      ``session_messages[-1]`` themselves.
+    - **Tool calls from transcript entries are flattened to text**: assistant
+      messages derived from the JSONL use ``_flatten_assistant_content``, which
+      serialises ``tool_use`` blocks as human-readable text rather than
+      structured ``tool_calls``.  Gap messages (from DB) preserve their
+      original ``tool_calls`` field.  This is the same trade-off as the old
+      ``_compress_session_messages(session.messages)`` approach — no regression.
+
+    Args:
+        download: The ``TranscriptDownload`` from GCS, or ``None`` when no
+            transcript is available.  ``content`` may be either ``bytes`` or
+            ``str`` (the baseline path decodes + strips before returning).
+        session_messages: All messages in the session, with the current user
+            turn as the last element.
+
+    Returns:
+        A list of ``ChatMessage`` objects covering the prior conversation
+        context, suitable for injection as conversation history.

+"""Unit tests for the transcript watermark (message_count) fix.
+
+The bug: upload used message_count=len(session.messages) (DB count).  When a
+prior turn's GCS upload failed silently, the JSONL on GCS was stale (e.g.
+covered only T1-T12) but the meta.json watermark matched the full DB count
+(e.g. 46).  The next turn's gap-fill check (transcript_msg_count < msg_count-1)
+never triggered, so the model silently lost context for the skipped turns.
+
+The fix: watermark = previous_coverage + 2 (current user+asst pair) when
+use_resume=True and transcript_msg_count > 0.  This ensures the watermark
+reflects the JSONL content, not the DB count.
+
+These tests exercise _build_query_message directly to verify that gap-fill
+triggers with the corrected watermark but NOT with the inflated (buggy) one.
