fix(graphrag): crash on project rename/path change (DF-009)

session_events.py::_on_projects_changed (runs on every project
create/rename/delete) called self.structure._refresh_project_combo() —
but that method only ever existed on GraphRenderer, not on
StructureGraphView itself (self.structure). Renaming a project or
changing its working-directory path raised AttributeError and crashed
the app.

Add StructureGraphView.refresh_project_list(), matching the existing
schedule_rescan/set_project/prewarm forwarding pattern, and call that
instead. Add a regression test
(test_refresh_project_list_forwards_to_renderer).

Logged as DF-009 in Task Tracking Template.xlsx — root cause, fix and
regression test recorded (row was empty in this local copy despite
being reported as already logged there).

-Branch: perf/fsg-performance
-
-Baseline: app import 1517ms; config 934ms; MainWindow 1742ms (offscreen, local machine).
-
-Packets completed:
-- P0: measured constructor with cProfile; dominant cost was provider model discovery (~0.7s network worker) and eager Workspace composition.
-- P2: cache history listing by directory mtime/query and coalesce sidebar refresh bursts.
-- P3: batch streaming Markdown/layout renders at 40ms; final content remains intact.
-- P4: bounded attachment discovery avoids sorting a full recursive tree when a cap is set.
-- P5: instrument monitoring log refresh; existing 30-day bounded window retained.
-- P6: defer provider model discovery to the first Qt event-loop turn.
-
-After: config 452ms; MainWindow 599ms in the same offscreen smoke benchmark (discovery no longer blocks construction).
-Streaming render count is now bounded by batch cadence rather than token count.
-Representative history benchmark: 1,000 files 383.6ms cold / 0.8ms cached on this machine.
-
-Relevant commits: c5cb258 (perf: defer discovery and reduce UI refresh work).
-Remaining bottleneck: eager Workspace/Co4E/Folder widget construction and import-time PySide6 overhead.
-
-Closure pass (starting HEAD 58b5220): Workspace now keeps Co4E, Folder, and GraphRAG as tab placeholders and creates each once on first selection. MainWindow benchmark: 357.6ms; first opens Co4E 143.1ms, Folder 148.0ms, GraphRAG 270.6ms; repeat opens 0.0–2.4ms. Focused lazy navigation/project tests: 15 passed. Pytest temp failures were ACL/path setup issues, not production assertions; a pre-created writable repository-local temp base allowed the focused gates to pass.
-Remaining startup cost is base PySide6/application import and eager Cowork shell; further lazy work is not justified without broader architectural risk.
-Performance initiative status: closed for this pass.
