Add Hindi translation

[aghyad97]

Adds messages/hi.json, a complete Hindi (hi) translation of messages/en.json.

Single file added. No changes to src/lib/locales.ts or src/providers/language-provider.tsx — registry wiring is handled separately.

Key parity

• 4,577 leaf keys compared against en.json: 0 missing, 0 extra
• 0 placeholder mismatches, 0 type mismatches
• bunx tsc --noEmit clean; bun run test 1282/1282 passing

Conventions used

• Everyday code-mixed register with Devanagari loanwords (फ़ाइल, ब्राउज़र, डाउनलोड, कंप्यूटर, पासवर्ड) rather than Sanskritized coinages
• Polite आप; करें imperative for buttons
• Western numerals; acronyms and format names left in Latin (PDF, JSON, SRT, TOTP…)
• Interpolated placeholders kept out of gendered verb agreement, restructuring the sentence where needed

Terminal punctuation
Source punctuation is mirrored, with the danda । standing in for the Latin full stop — 586 .-ending strings and the 65 !-ending strings all end in ।; ?, :, … and unpunctuated strings carry over unchanged.

Hindi has no native exclamation mark and does not conventionally use the borrowed ! for routine operation confirmations — Hindi UIs render these declaratively (कॉपी हो गया।, not कॉपी हो गया!). The ! in the English toasts is a tone convention rather than semantic emphasis, so it maps to the danda. The only ! characters in the file are the three literal !@#$ character-class examples, which are inherited from the source.

Worth a native speaker's eye

• HTTP status reason phrases were translated rather than kept as English tokens — 200 OK → ठीक है, 502 Bad Gateway → ख़राब गेटवे. Recognition rests on the numeric code. Reasonable to reverse if English tokens are preferred.
• Periodic table uses standard NCERT science terms (क्षार धातु, परमाणु क्रमांक, इलेक्ट्रॉन विन्यास) — deliberately more Sanskritic than the rest of the file, matching how these are actually taught.
• Sample/placeholder data was localized: example names → अमित/प्रिया/राहुल, आरव/नेहा; Meme Generator default text → ऊपर का टेक्स्ट / नीचे का टेक्स्ट.
• Mixed loan/native choices worth confirming: एक्ज़ीक्यूट vs पढ़ना/लिखना for chmod bits, सर्कल/इलिप्स over वृत्त/दीर्घवृत्त for CSS shapes, ओवरड्यू for invoice status, यूनिक शब्द over अद्वितीय.
• TextCaseConverter labels (UPPER, lower, Title, camelCase) left in English — Devanagari has no letter case, so translating them would destroy what the button demonstrates.
• TipCalculator.pays renders as भुगतान: rather than a verb, to avoid forcing gender agreement with an interpolated name.
