feat(mcp): sprints, epics, backlog, trash, checklists and release notes

Thirty new tools (54 in all) for what the API gained since the MCP:
create a project and read its public showcase; sprints (list, progress
and burndown, plan, change, start, close with carry-over, delete, move a
ticket in or out); epics and the backlog (list epics with progress, set
a ticket's parent, rank); bulk edit of up to 100 tickets by key, saying
which refused; the trash; checklists; following a ticket, removing a
relation, editing and deleting comments; editing and archiving releases,
drafting and saving their notes; notifications.

Searching filters by epic, sprint and dates and sorts by backlog order;
get_issue shows parent, checklist, commits and followers; create and
update take parent and start date.

API: `unreadOnly` and `dryRun` were documented as objects in the
OpenAPI; they are booleans now. Chapter 9 lists every tool; Word and PDF
regenerated.
