rewrites for ERASE/RENAME/CLOSE/COMMIT/UNLOCK/LOCATE/CONTINUE/
REINDEX/PACK/ZAP/KEYBOARD/RUN plus COUNT/SUM/AVERAGE/COPY/SORT/
LIST/DISPLAY/TOTAL/JOIN/UPDATE — 13 commands that were silent
no-ops in the parser before this round.

Also catalog the 14 PP completeness fixes the rules surfaced
(partial-pattern false-match, blockify substitution, list-aware

no-progress iteration leak, unreferenced logify/blockify cleanup,
nested `[...]`).

LABEL / REPORT explicitly deferred — niche xBase output-formatting
engines whose `.lbl` / `.frm` binary readers and pagination/group

checkpoint: season-wide bug fix campaign + infra

Cumulative season's silent-bug hunting (~62 fixes) across the FiveSql2
SQL engine, the Five compiler/runtime, and the hbrdd RDD layer. Saved
as a single checkpoint before refactoring the parser to delegate xBase
command translation to the preprocessor.

Highlights:

FiveSql2 engine (_FiveSql2/src/)
- prefix-glob index attach -> explicit convention (<table>_pk.ntx,
  <table>_uq.ntx, <table>.cdx) — fixes silent multi-row INSERT row-drop
- DROP/CREATE TABLE FErase chain extended (.cdx, .fsc, .fsv, .dbt, .fpt)
- COUNT(DISTINCT col) parsed + aggregated via hSeen hash
- UNION column-count mismatch returns SQL_ERR_GRAMMAR (was silent)
- DISTINCT + ORDER BY hidden-col leak fixed (trim before DISTINCT)
- Derived table FROM (SELECT...) + JOIN right-side derived
- Self-FK CASCADE depth 2+ via SqlGetSingleColPK pre-collect
- LAG/LEAD default arg uses SqlEvalRowExpr (handles -N const exprs)
- DATE literal round-trip validation (Feb 29 non-leap rejected)
- CREATE OR REPLACE VIEW; CREATE VIEW errors on already-exists
- AlterTable type dispatcher comma-wrapped (1-char type "A" no longer
  matches CHARACTER)

Compiler / runtime
- gengo: HB_ -> FV_ prefix on emitted Go function names (Five identity)
- gengo split: emit_block.go, emit_stmt.go, folding.go extracted
- parser/stmtreg.go nudges
- hbrt: debug TUI/CLI restructure (debugcmd, debugkey, termios_*),
  windows debug stubs collapsed
- thread/vm/value/class/pcinterp tightening from panic traces

RDD layer (hbrdd/)
- dbf: null bitmap support (null.go + null_test.go), mmap split
  (mmap_posix.go / mmap_windows.go), byte-level numeric parse
- ntx/cdx: windows mmap parity
- workarea + mem RDD: cross-area state-bleed fixes

RTL (hbrtl/)
- errorlog rewrite with platform-specific FD (errorlog_fd_unix /
  errorlog_fd_other)
- sqlscan, sqlhelpers, indexrtl, datetime extensions

Gates green at checkpoint:
- go test ./...        : PASS
- FiveSql2 SQL:1999    : 43/43
- Harbour compat       : 56/56
