feat(using-tasks): done-task archival rule, fix STATUS.md bloat (v1.3.0)

MINOR bump 1.2.0 -> 1.3.0. Adds a done-task archival rule: when >=10
green done blocks pile up in STATUS.md (checked at Session start step 7
and Task completion step 7), move them verbatim to
.tasks/archive/YYYY-MM.md (append, monthly file, one-time header,
committed on its own), leaving only active/paused/ready/blocked on the
board. This is the root-cause fix for the recurring "huge STATUS.md"
complaint -- orientation still reads the local board, but the board is
kept small so the read stays cheap.

Deliberately did NOT follow the task's literal instruction to swap
Read STATUS.md for tasks_get_status in the orientation flow: that rests
on a factual error. tasks_get_status returns ONE task's live status by a
known slug and cannot enumerate the board; tasks_aggregate is
cross-project + cache-based and does not index ready/done (its docs say
read STATUS.md directly for the current project). So no projects-meta
tool replaces the orientation board-read. The skill now warns against
both tools for board enumeration and points tasks_get_status at its real
single-task use.

Concept page concepts/using-tasks-status-archival.md + index + log
document the deviation for the paired review task. TDD N/A (markdown
policy). hermes/mapping + install untouched (separate baseline tasks).
