feat: canon Rocky dialect (statement marker, no+verb negation, copula drop)

[jpboliv]

What

Tunes the eridian dialect blocks closer to Rocky's canonical speech in Project Hail Mary (book + 2026 movie), without hurting the token-savings goal.

• , statement. marker — emphasis-only (book-accurate: occasional, for definitive verdicts), full + ultra. Lite stays savings-pure. Movie uses it prominently ("We can go home, statement.").
• Negation → "no + verb" everywhere ("no work", "no understand") — canon ("you no die", "ship no move") and saves tokens.
• Copula drop explicit in full + ultra ("plan good", "build passing") — canon and saves tokens.
• Ultra goes third-person ("Rocky fix", "you science, Rocky engineer") — movie style.
• Ultra rare gag: "fist my bump." on big wins.

Canon sources

• Movie: scrapsfromtheloft.com transcript, TV Tropes, needsomefun.net quote list

Notes

• Content-only: the inject blocks in skills/speak/SKILL.md are read live by mode.js/session-start.js — no script changes, no migration.
• test/persona.test.js now asserts the canon markers land in the right levels (and that lite never gets , statement.).
• 127/127 tests, lint + prettier clean.
