* fix(file-tools): handle UTF-8 BOM in read_file / write_file / patch
Some Windows editors prepend an invisible UTF-8 BOM (U+FEFF) to text
files. We had no awareness of it, so: read_file surfaced a phantom
U+FEFF as the first character; patch matches against the true first
line could miss; and a write/patch round-trip silently stripped the
marker, changing the file's byte signature.
Now:
- read_file / read_file_raw strip a single leading BOM so the model
never sees it (only on the first chunk — the marker lives at byte 0).
- patch_replace strips the BOM before fuzzy-matching (so an exact
first-line match works) and its post-write verification compares
BOM-stripped content.
- write_file restores the BOM when the original file had one and the
new content doesn't, mirroring the existing line-ending preservation
(detect on disk via a cheap `head -c 3` probe or reuse pre_content,
re-prepend across the edit). Guards against double-BOM.
Mid-content U+FEFF is left alone (it's data there, not a file marker).
Tests: TestBomHandling (real LocalEnvironment) — read-strips, raw-read
strips, write preserves, no-BOM-when-original-had-none, no-double-BOM,
patch round-trip preserves, patch matches first line through a BOM,
plus helper unit tests. 208 file-tool tests green.
* fix(kanban): respect mobile safe areas in task detail drawer
The task detail drawer is a body-level z-60 fixed overlay using
height:100vh starting at the viewport top. On mobile this puts the
drawer header behind the dashboard's fixed top bar (min-h-14, z-40)
and lets the bottom comment input sit under the browser's collapsing
nav bar.
- drawer: 100vh -> 100dvh (+ max-height:100dvh), 100vh kept as fallback
- head: padding-top honors env(safe-area-inset-top); mobile (<1024px,
matching the lg breakpoint where the fixed bar shows) clears the
3.5rem header
- comment-row + body: bottom padding extended with
env(safe-area-inset-bottom) so the bottom-most element clears the
mobile browser chrome
Mirrors the host shell idiom (100dvh + env(safe-area-inset-bottom) in
web/), and web/index.html already sets viewport-fit=cover so the insets
resolve. max()/calc() fallbacks leave desktop unchanged.
