chore(todo): close Python tree-sitter predicate bug as upstream-resolved

The treesit-query-error redisplay flood diagnosed 2026-04-26 no
longer reproduces.  Versions: emacs 30.2-3 (was 30.2-2 at the time
of the investigation, upgraded 2026-05-03), tree-sitter 0.26.8
(unchanged).  The upstream Emacs version string is unchanged, but
the Arch package revision bump most likely carries a downstream
patch to treesit.c's predicate translation.

Verified by re-running the documented repro: the exact failing query
from python.el captures cleanly via `treesit-query-capture', and
`font-lock-ensure' on a real .py file under `python-ts-mode' returns
with no `treesit-query-error'.  No local override needed.

Mark the todo.org entry DONE, fix the stale `inbox/' path on the
investigation-doc link (file now lives under `docs/'), update the
cross-reference from the grammar-bootstrap task to note this no
longer blocks it, and append a RESOLVED 2026-05-14 footer to the
investigation doc so future-me can see why it got closed.

+RESOLVED 2026-05-14
+-------------------
+Bug no longer reproduces against the current versions:
+  - emacs 30.2-3 (Arch package; upgraded from 30.2-2 on 2026-05-03)
+  - tree-sitter 0.26.8-1 (unchanged from the original investigation)
+
+The exact failing query from the investigation (python.el lines
+1188-1190, the keyword + self-as-keyword block) now runs cleanly
+under `treesit-query-capture'.  `font-lock-ensure' on a real Python
+file under `python-ts-mode' completes with no `treesit-query-error'.
+No local override applied to `modules/prog-python.el'.
+
+The upstream Emacs version string is unchanged (30.2 in both), but
+the Arch package revision bumped from -2 to -3 on 2026-05-03 -- most
+likely carrying a downstream patch that fixed the treesit.c predicate
+translation.  This matches option A from the fix-options list above
+("WAIT FOR UPSTREAM EMACS FIX").
+
+If the flood ever returns, restart the investigation from the
+REPRODUCTION block above against whichever emacs / tree-sitter
+versions are then installed.

-Fix surfaces are upstream (Emacs source or tree-sitter library) — local options are workarounds. Recommended next-session path: check whether Emacs 30.3 / master has a fix; if not, override =python--treesit-settings= in =modules/prog-python.el= to strip the loudest predicate-using queries (loses some highlighting, kills the redisplay flood).

 [2026-05-12] Visual review of the reading-width rework is done -- it's good. Not sure I actually need this nit fixed; the left-of-center bias is minor and the `+'/`-' keys let me nudge it. Parking here until I decide it bothers me enough.
