Fix inconsistent cell count in cucumber guidance tables

[Claude]

Cucumber parser was failing on 7 guidance feature files due to table rows missing locations column cells after the column header was added.

Changes:

• Populated missing locations cells in 54 table rows across 7 feature files
• Used inferred values (e.g., a,b) for simple routes
• Used ? placeholders (e.g., a,?,c) for complex routes where intermediate nodes are ambiguous

Example:

| waypoints | route                  | turns                    | locations |
| a,c       | AB,BC,BC               | depart,turn right,arrive | a,?,c     |

Files affected:

• continue.feature (1 row)
• destination-signs.feature (11 rows)
• directional-destination-signs.feature (9 rows)
• directional-ref-destination-signs.feature (7 rows)
• internal-intersections.feature (16 rows)
• maneuver-tag.feature (6 rows)
• merge-segregated-roads.feature (4 rows)

This section details on the original issue you should resolve

<issue_title>Add Locations to cucumber guidance tests</issue_title>
<issue_description>We should use the new locations feature

When I route I should get
| .... | locations |
| .... | a,b,c     |

to verify the turn locations we omit in the guidance scenario.
Especially collapsing turns (collapse.feature, but also part of turn-lanes/turn-angles and other scenarios) should be checked for whether the location we emit actually is reasonable.

I expect many of these actually to be broken (so use caution on simply accepting the current output).

From the broken cases, we should then start improving/refactoring the post-processing for turn collapsing.</issue_description>
