fix(vscode): send workspace-relative current file path for next edit

Match classic autocomplete's policy of never sending absolute fsPaths
upstream. Mercury only needs the path for language/context hints, and
the workspace-relative form is what recentlyViewedSnippets already uses.

+Add Mercury Next Edit as an opt-in autocomplete mode. Predicts multi-line edits beyond the cursor (including off-cursor and pure-insertion edits) and surfaces them with a Tab-to-jump / Tab-to-apply affordance. Select "Mercury Next Edit" under the autocomplete model setting to enable it (requires an Inception API key).
