W9-5: Tooltip sweep — HelpTip helper + per-view decode (#533)

* [W9-5a] Tooltip sweep foundation: HelpTip helper + shared cryptic badges

HelpTip: DRY wrapper over the verbose 3-element Radix Tooltip pattern so a
broad sweep stays a one-line wrap per site (falsy label short-circuits to the
bare child). Unit-tested (3 cases).

TaskStatusBadge + AgentStateBadge: the panel's most cryptic, most-frequent
elements (15 task lifecycle states, 11 agent states) had no explanation
anywhere. Add a per-state tooltip via HelpTip, with the canonical text in one
description map and exported as taskStatusDescription / agentStateDescription
so the per-view inline renderers (kanban, task header) reuse it instead of
re-declaring. This is part 1 of the W9-5 tooltip sweep; the per-view inline
surfaces follow in subsequent PRs.

* [W9-5b] Per-view tooltip sweep: decode cryptic badges, icon-only buttons, status dots

35 HelpTip additions across 22 panel components, reusing the W9-5a
helper plus taskStatusDescription/agentStateDescription. Tipped:
task-id/commit-hash/branch/PR badges, severity/origin/status badges,
priority (P0-P3), migration/shared flags, MegaTask umbrella badge,
Review Gate / For Resumption / Confidential note badges, icon-only
view/delete/edit/clear/show-hide buttons, semver bump + gate-state
badges, ahead-not-pushed badge. Skipped self-explanatory labeled
buttons and elements already carrying title=.
