docs(handoff-76): tee up the open issues as the next session's focus

Add §7 — the four open Gitea issues (#36 help, #37/#38 hints, #39 the
schema-cache bug) with per-issue scope reads, key code/ADR pointers, a
suggested order, and the tea commands to read them — so a new session
starts there before resuming features (user direction). Flag #38 as
needing a do/defer/close call. Refresh §1's commit list (5 commits, all
on main, unpushed) and the macOS full-run note; point §4 at §7.

+
+Per user direction (2026-06-22), the next session should **work the open Gitea
+issues before resuming feature work** (V4 journal, TU1 tutorial, etc.). There
+are **four open** (`tea issues list --state open --limit 100`; read a body with
+`tea issue <n> --fields body --output json < /dev/null | jq -r '.body'`, and
+comments with `tea issue <n> --comments < /dev/null`):
+
+| # | Label | One-line | This-session read on scope |
+| --- | --- | --- | --- |
+| **#36** | enhancement | `help <sql-form>` shows no distinct content — the seven advanced-mode SQL nodes carry `help_id: None` (a dedup hack for the `help` list; `src/dsl/grammar/mod.rs:915-918`), so e.g. `help select` resolves to nothing. The parse-error/usage layer (ADR-0042/H1a) already distinguishes them; only the `help` command lags. | **Contained.** Good first pick — a real, bounded gap. Touches H3/`help`; an ADR amendment may apply. |
+| **#37** | enhancement | Clause-concept hints — deeper teaching when the cursor sits inside a recognized *clause* (`on delete ⟨cascade\|set null\|restrict⟩`, the `create table` constraint slots, `with pk`, `1:n`/`m:n`), between tier-2's candidate list and the whole-form tier-3 block. Deferred extension of **ADR-0053** (H2). | **Medium scope, richest teaching value** — squarely on the pedagogy mission. Likely an ADR-0053 amendment. |
+| **#38** | enhancement | Pre-submit-diagnostic F1 route + ~33 `diagnostic.*` tier-3 blocks. Needs a `class`/`message_key` field threaded through **every** diagnostic-creation site (walker + validators). Deferred from ADR-0053 Phase C. | **Broad mechanism change for the most marginal value** (tier-2 already surfaces these). The issue itself says so. **Decision needed:** do, defer, or close as wontfix — escalate to the user. |
+| **#39** | bug | Simple-mode **Form-B insert** (`insert into T values (…)`) submitted faster than the post-DDL **schema-cache refresh** validates against stale schema → misparsed as SQL. Filed this session; repro + diagnosis (incl. `SchemaCache` at `src/completion.rs:53`, Form-B handling `src/dsl/walker/context.rs:155-157`) in the issue. | **Low impact** (no interactive-user hit; cast driver + tests pace). Fix is its own focused change (sequence the cache refresh with command execution, or validate against the authoritative schema). |
+
+**Suggested order (a recommendation, not a mandate — confirm with the user):**
+#36 (contained warm-up) → #37 (highest on-mission value) → #39 (bug; size the fix
+first) → #38 (get the user's do/defer/close call before investing in the broad
+threading change). All four are hint/help/parse-adjacent except #39; reading
+**ADR-0053** (the contextual-hint design) first will orient #37 and #38.
+
+No new labels needed (`bug`/`enhancement` cover them; ask the user before
+creating any). Issue-tracker etiquette + `tea` gotchas are in the project
+`CLAUDE.md` ("Issue tracking — Gitea via `tea`").
