chore: track docs/specs and docs/plans again — retire via git rm at cycle close

Drop the gitignore entries for both dirs; align the CLAUDE.md note from "git-ignored, local-only" to "git-tracked — committed while the cycle is live, removed (git rm) at cycle close". The durable record stays the ledger + git history; specs/plans are transient in the repo, present only for their own cycle.
