feat(using-tasks): session_break marker [v1.2.0]

Add a session_break marker so a task author can mark a task's
completion as a natural session boundary. After the task closes 🟢,
before tasks_claim_next, an autonomous agent prints the verbatim
SESSION BOUNDARY line and stops instead of chaining the next task.
Absent -> behaviour unchanged.

- STATUS.md format: optional **Session break:** field + new
  "### session_break marker" subsection (type bool|string, examples).
- Task completion step 6: after close, before claim-next, check the
  closed task's session_break; print boundary line + stop if present.
- Rules bullet "Honour session_break".
- Wiki concept page concepts/using-tasks-session-break.md + index + log.

MINOR bump: new optional capability, no existing behaviour changed.
Closes [session-break-using-tasks].

# using-tasks `session_break` marker
`using-tasks` v1.2.0 adds a `session_break` marker so a task author can mark a task's
completion as a natural place to **stop**, rather than have an autonomous agent immediately
chain into the next task via `tasks_claim_next`.
## Problem
An autonomous runner closes a task and, by default, claims the next one. There is no signal
for "this is a good seam to end the session" — so unrelated tracks get welded into one
ever-growing context, and the natural review/hand-off moment is skipped.
## Design
- **Marker:** `session_break` in the task's frontmatter (task-system delivery) or the
`**Session break:**` field in the task's STATUS.md block (local board mirror).
- **Type:** boolean or string.
- `true` → pause after close; next track is "see STATUS.md".
- `"<hint>"` → pause after close; the hint names the recommended next track.
- **Enforcement point:** `using-tasks` → Task completion, **step 6***after* the task is
🟢 and committed, *before* any `tasks_claim_next` / starting the next task.
- **Behaviour when present:** print the SESSION BOUNDARY line verbatim, then stop (do not
claim the next task).
- **Behaviour when absent:** unchanged — claim / start the next task as usual.
### Verbatim message
```
🔚 SESSION BOUNDARY — [slug] закрыта. Рекомендую завершить текущую сессию. Следующий трек: [value | "см. STATUS.md"]
```
`[slug]` = the closed task's slug. `[value | "см. STATUS.md"]` = the marker's string value,
or the literal `см. STATUS.md` when the marker is just `true`. The wording is fixed so the
boundary is greppable and recognisable across sessions.
## Why a marker, not a heuristic
The decision of *what counts as a stopping point* belongs to whoever scoped the work (the
delegating workshop), not to the runner mid-flight. A heuristic ("stop after N tasks", "stop
when tired") would either over- or under-fire. An explicit, opt-in marker keeps the default
unchanged and makes the boundary a deliberate authoring choice.
## Versioning
MINOR bump (1.1.0 → 1.2.0): new optional capability, no existing behaviour changed.

## [2026-06-09] decision | delegate-task-negative-trigger-fp — `delegate-task` 0.2.0→0.2.1 (PATCH): fixed 5/5-consistent false-positive on «создать задачу себе». Root cause: self-task phrase shares stem «создать задачу» with the «создать задачу на агента» positive trigger; the abstract "Does NOT apply when doing the work yourself" carve-out can't beat a literal stem-match under the 1%-rule. Fix: made the negative literal + routed («создать задачу себе» / «task for myself» / «поставить себе задачу» → using-tasks) in description + body disambiguator («на агента»/«агенту» = delegate; «себе» = own board). Re-verified via fresh-context subagent trigger run: positives 5/5 (no regression), negative 4/5 → using-tasks (was 0/5); the 1 residual miss was an eval-harness artifact (forced skill-name-before-reasoning), not description ambiguity. Concept page written; reusable principle = put the exact colliding negative phrase with an explicit →sibling route, literal beats abstract.
## [2026-06-09] decision | using-tasks-session-break — `using-tasks` 1.1.0→1.2.0 (MINOR): added the `session_break` marker. Task author sets `session_break: true | "<hint>"` in task frontmatter (mirrored as `**Session break:**` on the local board); after the task closes 🟢, before `tasks_claim_next`, an autonomous agent prints the verbatim line `🔚 SESSION BOUNDARY — [slug] закрыта. Рекомендую завершить текущую сессию. Следующий трек: [value | "см. STATUS.md"]` and stops instead of chaining the next task. Absent → behaviour unchanged. Enforced in Task completion step 6 + Rules bullet + format docs. Marker not heuristic: the stop-point is an authoring choice, not a runner guess.

### `session_break` marker
A task may carry a `session_break` marker — set by whoever defines the task (e.g. the delegating workshop) when its completion is a natural place to stop and start a fresh session. It signals an autonomous agent: *finish this task, then pause instead of immediately claiming the next one.*
- **Type:** boolean or string.
- `session_break: true` — pause after close; the next track is "see STATUS.md".
- `session_break: "<hint>"` — pause after close; `<hint>` names the recommended next track.
- **Where it lives:** in the task's frontmatter when delivered via the task system (`session_break: true` / `session_break: "<hint>"`); mirrored on the local board as the optional `**Session break:**` field in the task's STATUS.md block.
- **Absent →** behaviour is unchanged: close the task and continue as usual.
The check is enforced in the **Task completion** flow below (after close, before claiming the next task).
