New placement option 'silent': the transition phrase marks the scene
boundary but is stripped from the output entirely. Neither the previous
nor the next segment contains it. Available globally and as a per-entry
override on custom transitions.

Trailing \b after a non-word character (like '.') never matches since
\b requires a word char on one side. Custom triggers ending with
punctuation now use (?=\s|$) as the end boundary instead, so
"Scene cut." correctly splits prompts.

- Global setting in Studio Refiner tab: "Transition placement" (start/end).
start = transition opens the new segment (existing default behavior).
end = transition closes the previous segment instead.
- Per-entry placement override in Transitions tab (global/start/end).
Custom transitions can pin their placement regardless of the global setting.
- transition items gain a placement field (global/start/end, defaults to global).
- load_custom_transition_triggers returns {trigger_lower: placement|None} so
the split function can do per-trigger lookups efficiently.
- refine_v2 and Studio.run() wired with split_transition_placement parameter.

The [a-z][\w-]* alternative matched any word after "scene", turning
"scene proceeds", "scene features", "scene shows" etc. into false
transition split points. Removed the over-broad alternative - the
pattern now only matches numbered scenes (scene 1, scene -2) and
"scene minus <label>" forms.

When the stacking fix merges a pure-transition segment into the next one,
it now uses a space instead of ", " if the segment ends with an article
(a/an/the). This prevents "the scene then cuts to the, next view" when
"next" is also a transition word and the segments get merged mid-phrase.

If a prompt ends with a transition phrase plus nothing (or just a lone
article like "the"), the last segment is now dropped rather than kept
as a near-empty scene. Covers cases like "...K/DA Kai'Sa, the scene
then cuts to the" where the user did not complete the transition.

- Shortcuts: allow empty string as a valid replacement to remove matched phrases
from prompts; post-pass cleans up orphaned commas/spaces left by removals
- Shortcuts: add cross-shortcut longer-phrase-wins test confirming ordered
alternation handles multiple shortcuts with overlapping triggers correctly
- Transitions: new user-editable transition word list stored in transitions.json;
custom triggers extend the built-in split pattern at runtime, keyed by name
- Transitions: Studio JS gets a dedicated Transitions tab (name, trigger, enabled)
with Add/Refresh/Import/Export toolbar
- Transitions: four API routes mirroring shortcuts (GET, export, save/delete, import)
