contextlake 8.8.0

Added

• contextlake schedule: a self-scheduler. Measures how long a run takes and how often your
  repositories change, works out an interval from the two, and installs a systemd user timer or
  a crontab entry that keeps the mirror and the knowledge layer current on its own, with no unit
  file or cron line to write by hand. Core tier: works without the [kb] extra.
  recommend, status and list read only; install, interval, reset and uninstall
  write. Ad-hoc jobs run any contextlake command on their own interval:

  contextlake schedule interval 6h run -- kb wiki --force

  Ten schedule_* config keys, an honest split between what systemd and cron can each do, and a
  container refusal for state that will not survive a restart. Discarding measured history
  (--purge, reset --history) renames the history file to a .discarded sidecar instead of
  deleting it, so a mistaken discard is recoverable. See Scheduling runs.

• branch_map: per-repository branch pins. branch puts the whole fleet on one branch,
  which is the common case and not the only one. branch_map takes comma-separated
  pattern=branch pairs using the same globs as repo_filter, so one team can track
  develop while a legacy tree sits on maintenance and everything else follows the
  most-active selection. First match wins, so a specific entry can precede the glob that
  would otherwise catch it. It beats branch, falls back to it, then to the selection.
  A repository whose mapped branch does not exist is reported as unpinned, exactly as
  branch already does, rather than being switched to something else.

  branch_map = team/api=develop, legacy-*=maintenance

Changed

• bootstrap gained --force. Rebuilds everything instead of only what changed: every
  repository re-parsed, every node re-embedded. It did not exist as a flag before; it is what
  schedule's periodic full cycle runs.

• configuration.md's example config now shows the scoping keys. repo_filter, branch
  and branch_map were documented in the settings table but absent from the example anyone
  copies, so the two that already existed were easy to miss.
