Task: Add a default sqliterc with formatting and ergonomic defaults

A committed, fully-commented projects/ores.sql/utility/sqliterc.sql that the sqlite3 shell can load to get headed box output, wide non-wrapping columns, a visible NULL marker, query timing, and connection-level safety defaults.

• .mode box --wrap 0 so long values render on one line (verified).
• .headers on, .nullvalue '∅', .timer on, .changes on.
• PRAGMA foreign_keys = ON and PRAGMA busy_timeout = 5000 active.
• Every active entry is commented; journal_mode left commented with rationale.
• sqlite3 -init projects/ores.sql/utility/sqliterc.sql loads cleanly.

Reproduce the wrapping complaint against the installed sqlite3 to find the real lever (.mode box --wrap 0) rather than guessing, and verify each dot-command is real before commenting it. Then rewrite the rc file in sections — output formatting, ergonomics, session pragmas, handy levers — with a comment on every active entry, enabling only per-connection settings and leaving persistent ones commented. Finish by smoke-testing with sqlite3 -init.

• Removed the original .alias example — .alias is not a real sqlite3 dot-command (verified against 3.46.1).
• Plain .mode box was confirmed to wrap long values even when no ~/.sqliterc is present; --wrap 0 disables it.

rc file written and smoke-tested with sqlite3 -init: a long value renders on a single full-width line, NULL shows as ∅, PRAGMA foreign_keys reports 1, and PRAGMA busy_timeout reports 5000. No load errors.
