release-doc: reach the kernel and CI repos the repo table still missed

[igorpecovnik]

Follow-up on the three defects reported against /releases/26.8/. Two of the three are already fixed on main; this PR closes the gap left in the third, plus a related bug in the board-tier collector.

Status of the three reported defects

#	Defect	Status
1	"All changes" renders flat, 780 entries inline	✅ Already fixed on main — generate-release-doc.py wraps the list in ??? abstract "{n} merged pull requests in this release". No change needed.
2	Grouping keys off title keywords instead of source repository	⚠️ Partly fixed on main (49a745e), but the repo tables miss several repos. This PR.
3	Four board status entries have no PR link	✅ Already fixed on main (49a745e) — collect-board-tier-changes.py now falls back to gh api repos/…/commits/{sha}/pulls. The committed 26.8.md has all four links (#9991, #10412, #10459, #10220). A latent case remained; see below.

Verifying #2 against the reported examples

Every misfiled PR named in the report already classifies correctly on main:

ok  armbian/configng   armbian-install: fix boot on UEFI systems            -> Tooling
ok  armbian/configng   install-engine: silence null-byte warnings           -> Tooling
ok  armbian/configng   install: keep the Rockchip reserved window           -> Tooling

ok  armbian/armbian.github.io  Update vendor logo                           -> Build framework and CI

What this PR fixes

Five repos in the brief's rule set have no entry in either table, so their changes are still classified by title alone:

Repo	Was	Now	Why the pattern missed it
armbian/uwe5622	14 in Other, 1 CI, 1 Tooling	Kernel and U-Boot	Out-of-tree wifi driver, but the name is the chip — no wifi- prefix, no -dkms suffix
armbian/phytium-linux-kernel	Build framework and CI	Kernel and U-Boot	Vendor comes before linux, so startswith("linux-") misses it
armbian/linux	—	Kernel and U-Boot	Exactly linux; the rule needs linux-
armbian/distribution	Tooling / CI (split)	Build framework and CI	No entry
armbian/shallow	CI by luck of the title	Build framework and CI	No entry

Also added while in the table, matching the brief's "firmware blob" class alongside rkbin and qcombin: armbian/mtkbin, armbian/odroidc2-blobs, armbian/sunxi-DT-overlays.

Repo lookups are now case-insensitive — the org spells repos both ways (MorseMicro-DKMS, sunxi-DT-overlays), and the digest carries whatever GitHub reports.

Beyond the brief's list

One addition not in the brief, called out for review: armbian/scripts → Tooling. The repo is literally "Armbian Linux Support Scripts" and its one 26.8 entry sat in Other. Say the word and I'll drop it.

Effect on the real 26.8 dataset

Replaying all 782 entries from the published 26.8.md through the classifier:

Group	Before	After
Boards	124	124
Kernel and U-Boot	267	283
Desktop	8	8
Build framework and CI	221	220
Tooling	91	90
Other	71	57

18 entries move, all into a better home. Boards and Desktop are untouched, so nothing that was already right gets disturbed.

configng / imager PRs under Boards or Kernel and U-Boot: 0.

Latent bug in collect-board-tier-changes.py

Separate from #3's gh api fallback. A board that moves twice in one window (wip → csc → conf) correctly reports the widened range, but keeps only the newest hop's PR link. If that newest hop is a merge-queue commit nothing can resolve — no (#123) subject, absent from the digest, and gh api returns zero or several PRs — the entry renders unlinked even though the older hop carries a perfectly good (#123).

Fixed by backfilling: the newest hop still owns the link, since it produced the tier the board ends the window on; an older hop's link is used only when the newer one has none.

Reproduced with a two-hop fixture where the newest commit is unlinkable:

before:  demoboard: wip -> conf (no PR link)
after:   demoboard: wip -> conf armbian/build#123

Verification

• Both scripts compile.
• 31-case classifier table covering every repo in the brief's rule set, the reported misfiles, configng desktop modules (which must still beat the repo home and reach Desktop), and armbian/build falling through to the title heuristics: 31/31 pass (25/31 before this PR).
• Full 782-entry 26.8 replay as above.
• The weekly digest workflow is untouched.

Walkthrough

The board transition collector now preserves an existing PR link and fills a missing link from the current transition when available. The release document generator adds fixed classifications for more kernel-related repositories, adds home mappings for distribution, shallow, and scripts, and performs case-insensitive repository matching.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 262f0

Mixed-case repository IDs can bypass the new repository mappings, causing release changes to appear in the wrong documentation sections. The lookup should be normalized consistently before merging.

Normalize REPO_HOME lookups for mixed-case repository IDs.

repo_fixed_group() lowercases repo, but classify() still calls REPO_HOME.get(repo) at Line [331]. Mixed-case identifiers such as Armbian/distribution bypass these new mappings and fall through to title-based classification. Use the same normalized key for REPO_HOME.

Proposed fix

-    home = REPO_HOME.get(repo)
+    home = REPO_HOME.get(repo.lower())
