Jinwoo Hong b997fcc77a fix(session-search): try phrase and AND routes for prose queries before OR (#20754)
* fix(session-search): try phrase and AND routes for prose queries before OR

An exact sentence pasted out of a transcript was not returned. The route
ladder only ran the phrase and AND rungs for a literal-looking query, so
prose fell straight to OR, where the sentence's common words filled the
candidate limit with recent sessions and the old session holding the
sentence never reached ranking.

The planner now carries a `phrase` candidate: the query's tokens in order
with stop words kept, which is what the sentence is actually indexed as.
The ladder runs phrase then AND over those tokens for every query of two
or more tokens. A one-token query still takes the rung only when it
looked literal. `incomplete` is reported by the rung that answered rather
than accumulated across every rung tried.

* fix(session-search): mark a snippet with the route that retrieved it

A phrase hit was highlighted with the OR expression over the stop-word
stripped terms, so an exact sentence rendered as scattered bold words with
its stop words plain. The snippet now uses the expression the route
matched by: one run for a phrase, every typed word for AND, the terms for
OR.

* fix(session-search): repair a prose phrase without dropping its stop words

Typo repair re-planned the query from `plan.body`, which prose has already
had its stop words removed from. `relay is droppng frames` therefore came
back as the plan for `relay dropping frames`, and the phrase rung searched
for a sentence nobody wrote: the transcript holds `relay is dropping
frames`, so the exact match fell through to AND.

The repair now maps over `plan.phrase`, the tokens as typed, and re-plans
from those. Only terms the body holds are offered to the corrector, so a
stop word is still never repaired, and the re-plan recomputes the body
from the corrected sentence exactly as before.
