fix(board): plan/brief use actual debt, not raw pending mail

board.sh --plan group 2 and --brief conflated every unhandled inbox
message with an obligation to reply, including ones the sender
declared reply-expected: no (a notice, not a request). Reported by
morning-driver (2026-08-11), independently reproduced against the live
mailbox on 2026-08-13: 27 of 72 pending messages were notices. Both
paths now join against coord-count.sh's owed column instead, so a
done/deferred/blocked repo whose only mail is FYI no longer gets a
plan tab, and --brief no longer counts a notice as an obligation. The
table's raw INN column is unchanged by design.

While extending that join with a second lookup file, found and fixed
a more severe, independent defect: the existing $UNBLOCKS/$RECORDS
join used the NR==FNR awk idiom, which silently empties the entire
plan whenever the first file is empty -- i.e. whenever the repo tree
has zero blocked repos, a common, ordinary state, not an edge case.
Verified against the shipped 0.21.0 script. Fixed by matching on
FILENAME instead of cumulative line counts, for both lookup files.

Also repoints the README's governance link at repo-standard's
canonical GOVERNANCE.md (was pointing at the marketplace's copy),
per org-ops D11.

board-selftest.sh: 142 -> 150 checks. Version 0.21.0 -> 0.22.0.

+  unhandled message in the inbox, including ones the sender declared
+  `reply-expected: no`. That is a notice, not a request, and 0.11.0 gave
+  `coord-count.sh` a second column (`owed`) for exactly this distinction - but
+  `board.sh` never read it. Reported by morning-driver (2026-08-11) and

+  chain-root `$UNBLOCKS` join below), so a `done`/`deferred`/`blocked` repo
+  whose only mail is FYI no longer gets a tab, and `--brief` no longer counts a

+  (2026-08-10) that declined to build this filter, on the premise that "the
+  arrival of the request IS the admission signal" - a premise that assumed
+  group 2 already meant requests. It didn't; the code computed pending, the
+  comments already said "owed" throughout, and the plan's own printed header
+  ("Utelatt naar repoet verken skylder svar...") already claimed the exclusion
+  was debt-based. The fix makes the code match what its own comments and
+  header already promised. Pinned by board-selftest.sh section 8/12 fixtures
+  `repo-done-fyi` (pending 2, owed 0 - excluded) and `repo-blocked-mixed`

+  raw scan (`RECORDS` field 6) are UNCHANGED - they answer "what is the state
+  of every repo," not "who is waiting on you," and stay on raw pending by
+  design.

+  **The `$UNBLOCKS`/`$RECORDS` join used `NR==FNR` through 0.21.0, and that
+  idiom silently drops the entire plan whenever the FIRST file is empty - fixed
+  to `FILENAME==` comparison in 0.22.0, found while adding the `$OWED` join
+  above.** Verified against the shipped 0.21.0 script: one in-progress repo
+  with an unhandled inbox message, zero blocked repos anywhere in the tree
+  (so `$UNBLOCKS` is empty, which is a common, ordinary tree state, not an
+  edge case) - `--plan` printed "0 tabber". `NR==FNR` is only true for the
+  FIRST file's own lines; when that file is empty, `FNR` and `NR` stay equal
+  for the ENTIRE next file too (not just its first line - verified with a
+  minimal awk reproduction), so every record in it is misrouted into the
+  `ub[]` branch and dropped via `next`. This was invisible to
+  board-selftest.sh because the fixture tree has carried at least one
+  `blocked` repo since the chain-root feature shipped, and it was invisible
+  on the real tree because `~/repos` currently always has one too - neither
+  is a guarantee. `FILENAME==UBF`/`FILENAME==OWF` compares the exact path,
+  never line counts, so an empty lookup file degrades to "nothing matched,"
+  never to "everything after it is misrouted."
