fix(context): read documented '## P1 — Today' plain tasks in live context (#2186)

resolveTodayTasks only matched a bare '## Today' heading and bold-prefixed
'- [ ] **task**' lines, while the daily-task-manager skill's documented
Output Format writes '## P1 — Today' with plain '- [ ] task' lines — so
documented writes surfaced zero tasks in live context.

Reader now accepts both heading forms and both line forms, two-step: the
legacy bold prefix extracts just the task name (dropping trailing metadata),
falling back to the plain full-line form.

Salvaged from PR #2188 (reader-side half). The skill-doc rewrites in that PR
are dropped: master #2938 kept ops/ synced and made put_page write-through
durable, so the 'gbrain get/put ops/tasks' docs are correct as-is. The PR's
single-regex line matcher is replaced with the two-step match because its
alternation captured '**name** — metadata' verbatim for bold lines.

Takeover of #2188. Fixes #2186.
