docs(why-ocp): reorder bullets + soften alignment framing + visceral hooks

The "Why OCP?" section previously led with technical/governance bullets
(SSE heartbeat, alignment, models.json) and buried the most relatable
selling points (LAN multi-user keys, ocp-connect IDE auto-config, cache).
First-time readers stopped reading before reaching the bullets that would
have sold them on the project.

Changes (README.md only, line 19-26):

1. Reorder: human-relatable benefits first, governance discipline last.
   New order: LAN multi-user → ocp-connect → cache → quota → SSE heartbeat
   → alignment → models.json. Quota is split out from the old combined
   "quota + cache" bullet so each gets its own one-liner.

2. Soften the alignment bullet's framing. The previous prose flagged
   "Other Claude proxies have shipped exactly that" and was deleted —
   no need to call out competitors. Replaced with a measured "LLM-assisted
   code drifts easily — it's tempting to invent plausible-looking endpoints
   that cli.js doesn't actually use" plus a deliberately understated
   payoff: "your setup keeps working when cli.js ships its next minor."

3. Add visceral hooks where bullets benefit from them:
   - SSE heartbeat: "If you've ever watched your IDE die at the 60s idle
     mark during a long Claude tool-use pause — that's nginx/Cloudflare
     default behavior" (frames the problem in user-felt terms before
     describing the fix).
   - Per-key quota: concrete example "set a kid's iPad to 20/day, a
     partner's laptop to 100/week" (replaces abstract "limits per key").

4. Cache bullet now explicitly states the per-key isolation guarantee:
   "cross-user pollution is impossible by hash construction, not by
   application logic" — this addresses the most common pre-adoption
   concern (and reflects the v3.13.0 D1 design).

5. Total length compressed ~20% despite added context — old bullets had
   redundant "what" descriptions; new bullets lead with the "what for".

Doc-only change. server.mjs not touched. ALIGNMENT.md Rule 5 (cli.js
citation requirement) does not apply. Same pattern as #68, #69.
