fix(workflow): correct grep anchor and add threshold=0 guard (#1979)

Two correctness bugs from @trek-e review:

1. Grep pattern `^<task` only matched unindented task tags, missing
   indented tasks in PLAN.md templates that use indentation. Fixed to
   `^\s*<task[[:space:]>]` which matches at any indentation level and
   avoids false positives on <tasks> or </task>.

2. Threshold=0 was documented to disable inline routing but the
   condition `TASK_COUNT <= INLINE_THRESHOLD` evaluated 0<=0 as true,
   routing empty plans inline even when the feature was disabled.
   Fixed by guarding with `INLINE_THRESHOLD > 0`.

Added tests/inline-plan-threshold.test.cjs (8 tests) covering:
- config-set accepts the key and threshold=0
- VALID_CONFIG_KEYS and planning-config.md contain the entry
- Routing pattern matches indented tasks and rejects <tasks>/</task>
- Inline routing is guarded by INLINE_THRESHOLD > 0

**Primary routing: task count threshold (#1979)**
If `TASK_COUNT <= INLINE_THRESHOLD`: Use Pattern C (inline) regardless of checkpoint type. Small plans execute faster inline — avoids ~14K token subagent spawn overhead and preserves prompt cache. Configure threshold via `workflow.inline_plan_threshold` (default: 2).
If `INLINE_THRESHOLD > 0` AND `TASK_COUNT <= INLINE_THRESHOLD`: Use Pattern C (inline) regardless of checkpoint type. Small plans execute faster inline — avoids ~14K token subagent spawn overhead and preserves prompt cache. Configure threshold via `workflow.inline_plan_threshold` (default: 2, set to `0` to always spawn subagents).
If `TASK_COUNT > INLINE_THRESHOLD`: Apply checkpoint-based routing below.
Otherwise: Apply checkpoint-based routing below.
