continual-learning: support user-owned cadence config and repo denylist

[KleinPerkins]

Request

Please let the continual-learning plugin read durable user-owned configuration for:

• cadence: minimum turns and minimum minutes before the stop hook can trigger
• repo denylist: owners, slugs, and/or path prefixes where the miner should not write AGENTS.md

Current gap

The marketplace stop hook currently carries inline cadence environment variables in hooks/hooks.json. Local users can patch the plugin cache, but that is brittle because marketplace cache refreshes can restore the upstream defaults.

A companion publisher can prevent publishing from denied repos, but it cannot prevent the marketplace miner itself from writing local AGENTS.md in a workspace where the plugin is enabled.

Desired behavior

A stable config source, for example under the user's Cursor config directory, would allow:

• permanent cadence such as 3 turns / 15 minutes without trial expiry
• hard repo deny before any local AGENTS.md write
• no cache patching or generated hook-command rewrites
• a clear migration path for local governance tools to retire cache projection

Thanks.
