cleanup: 3 tracked .bak files, 1 stale log, doc updates

`qemu-debug-boot.log` (1.7 MB, May 20) — stale
debug log from a QEMU session 1+ month ago, removed
from working tree (untracked, in repo root).

`local/recipes/dev/bison/source/doc/bison.info.bak`
(16 KB) — emacs/autotools backup file that got
tracked by accident. Removed from git tracking.

`local/recipes/wayland/libwayland/recipe.toml.bak`
(22 lines) — backup of libwayland recipe from the
C-1 fix (libwayland `patches = [redox.patch]` line
removal). The actual fix is in the working tree;
the .bak was stale.

`recipes/libs/ncurses/recipe.toml.bak` (34 lines) —
backup of ncurses recipe from an earlier session.
Stale.

  - Updated commit list with 5 commits not previously
    listed: ffbbf4935c (lint carveout), d2c982dc2a
    (broken patches refs), f1802f6f2b (qtbase NO-OP
    seds), a123bf1c5d (sddm migration), a399e7da08
    (stale tracked files)
  - Final lint state: 0 errors / 173 recipes clean
    (was '10 remaining errors' in the previous version)
  - Stale tracked files section: documents the
    a399e7da08 cleanup (617 files / 1.3M lines removed)
  - Next steps: C-8 deferred with explicit user note
    'DO NOT clean up unzipped sources — they may
    contain the user's in-flight WIP build state'

+## Final lint state (post-C-7)
+
+`make lint-recipe` is **0 errors / 173 recipes clean** as of
+`a123bf1c5d` (sddm migration) — the last remaining 2 R2
+errors (sddm 19 seds, qtbase 2 seds) were both addressed
+in the lint cleanup commits `f1802f6f2b` (qtbase NO-OP

+
+The 2 remaining R1 errors (redbear-sessiond, libwayland
+referencing missing patch files) were fixed in `d2c982dc2a`
+by removing the broken `patches = [...]` lines.

+The lint rule R2 was also refined in `ffbbf4935c` to
+distinguish upstream-source seds (`${COOKBOOK_SOURCE}/`)
+from build-time seds (`${COOKBOOK_STAGE}/`,
+`${COOKBOOK_BUILD}/`, `${COOKBOOK_SYSROOT}/`). Build-time
+seds are exempt because they're build-time adjustments to
