docs: fix documentation drift — missing schedule syntax options

[github-actions]

Documentation Freshness Audit

This audit found the following inconsistencies between code and documentation:

Findings

Area	Issue	File(s)
Schedule syntax	bi-weekly, tri-weekly, every N days, and every N weeks are fully implemented in src/fuzzy_schedule.rs and documented in docs/schedule-syntax.md, but missing from README.md	README.md
Schedule syntax	The frequency table is missing every N days and every N weeks options; valid hour intervals described as "must divide 24" rather than listing the actual valid set	prompts/create-ado-agentic-workflow.md

Details

src/fuzzy_schedule.rs implements and tests the following schedule variants:

• EveryDays(u8) — every 2 days, every 3 days, etc.
• every N weeks — accepted input, converted to EveryDays(N*7)
• BiWeekly — bi-weekly / biweekly (every 14 days)
• TriWeekly — tri-weekly / triweekly (every 21 days)
• Valid hour intervals: [1, 2, 3, 4, 6, 8, 12] (all confirmed in code at line 468)

docs/schedule-syntax.md correctly documents all of these (lines 61–63).

README.md schedule syntax block was missing the multi-day/special-period variants entirely.

prompts/create-ado-agentic-workflow.md (the primary guide AI agents use to create workflows) had the bi-weekly/tri-weekly rows but was missing every N days and every N weeks. The "must divide 24" wording for hour intervals was also imprecise — the actual constraint is a fixed set [1, 2, 3, 4, 6, 8, 12].

Applied Fixes

• Added every 2 days, every 2 weeks, bi-weekly, tri-weekly examples to README.md schedule syntax block
• Clarified valid hour intervals in README.md comment (valid: 1, 2, 3, 4, 6, 8, 12)
• Added every 2 days and every 2 weeks rows to the frequency options table in prompts/create-ado-agentic-workflow.md
• Clarified valid hour intervals in the prompts frequency table
