feat(identity): sync.sh and syncro.md read from identity.json

Phase 2 migration complete:

sync.sh:
- Read Python command from identity.json first (.python.command)
- Fall back to auto-detection for legacy machines
- Eliminates per-session detection overhead

syncro.md:
- Read Ollama endpoint from identity.json (.ollama.endpoint // .ollama.fallback)
- Read Python command from identity.json (.python.command)
- Both sections have legacy fallbacks with detection
- Eliminates 2-second curl probe on every write operation
- Updated day-of-week verification code example
- Updated Ollama draft call section

Impact: All scripts now read machine-specific config from identity.json
(populated by migrate-identity.sh). Faster, explicit, offline-safe.

 **Appointment dates — always verify day-of-week before the preview.** Day-of-week math is easy to get wrong. Before including any appointment date in a preview, run a live check and display the full day name alongside the date (e.g. "Saturday 2026-05-23", never just "2026-05-23"). The user confirms the day name at the preview step — if the name is wrong, the date is wrong. Incident: #32312 booked Sunday May 24 instead of Saturday May 23 (2026-05-21). Reported by Winter.

 **After every write operation, post a summary + link to #bot-alerts.** Every ticket created, updated, closed, or commented, every billing run, and every customer created posts a one-line alert to the team's live feed in Discord. This runs AFTER the write succeeds (never before — no alert for an action that didn't happen) and applies regardless of who runs the skill or where (workstation or the Discord bot). Read-only commands (list / view / search) post nothing. Full format, link mapping, and helper call are in "Post to #bot-alerts" below.
