3460ef3993 editor: fix viewport-on-open, chunked-buffer drift, add size guard (Phase 3 code)
- Viewport: swallow the opening tap/scroll (justOpenedAt window) and
  re-clamp ScrollOffset to [0,MaxScroll] in EditorLayout so a short file
  never opens past its content (blank viewport).
- Chunked buffer: replace the fixed i*chunkSize slot model (which drifted
  after length-changing edits and could re-read stale disk for shifted
  tail chunks) with an ordered chunk slice + prefix-sum byte offsets.
  In-range files now load fully on open (SetContent), so there is no lazy
  load and no stale-disk re-read. Edits splice only the affected chunk(s).
- Size guard: files > MaxEditableFileSize (50 MB) show a 'too large to
  edit' notice instead of loading; the browser still lists them. Edit
  handlers (KeyDown/ReplaceRange) are no-ops for too-large files.
- Tests: rewrite chunked_buffer_test.go for prefix-sum correctness (insert/
  delete across chunk boundaries, rune->byte after edit); fix the large-file
  e2e expectation to the shift-correct ground truth.

c9c0d47f2a editor: route file taps to in-app editor; add gated IME commit logging
- ui.OpenFile now calls the in-app editor OpenFile(path) instead of the
  external openfunc (Android Termux bridge). The old wiring sent every
  browser-row tap through the Termux bridge, which crashed on Android 7+
  with FileUriExposedException (file:// Intent URI) and bypassed the editor.
- OpenFile no longer invokes TheState.open; it is retained as a dormant
  external hook for a future 'open externally' action.
- Add imeDebugLog (off by default) verbose per-commit IME logging in
  HandleReplaceRange, plus currentEditorText helper, to aid on-device
  IME commit/cursor-sync debugging.

72b3c3f9c1 editor+ui: complete Android IME wiring (SelectionCmd, SnippetCmd, InputHintOp)
Finish Phase 1 items 1, 2, 4, on top of the range-handling done in 9b78219:

- TextField.Draw now emits, when focused:
  * key.InputHintOp{HintText}        (item 4: enable text keyboard/autocorrect)
  * key.SnippetCmd (the visible window as the snippet, Range {0,len})
                                              (item 2: swipe/autocorrect source)
  * key.SelectionCmd (caret, window-relative rune index)
                                              (item 1: IME selection sync)
  The snippet is the visible window (not the whole file), so the IME treats
  the window as the document and reports EditEvent.Range window-relative.

- HandleReplaceRange now resolves the window-relative range against
  IMEWindowText and offsets by IMEWindowStartByte to address the buffer
  (string and chunked paths). Falls back to the whole buffer when layout
  has not set the window (tests).

- EditorState gains IMEWindowStartByte / IMEWindowText, set during layout.

- Add runeCount helper (utf8 leading-byte scan) in the ui package.

- Fix a data race in three editor e2e/integration tests: they called
  OpenFile from the test goroutine while the logic goroutine ran layout;
  now wrapped in withState so the state write happens on the owner.

Tests: ime_range_test.go gains windowed-path coverage (string+chunked).
go build, go test, go vet, and go test -race are all green.

9b782190fa editor: honor key.EditEvent.Range in HandleReplaceRange (IME swipe/autocorrect)
The IME commit path (swipe-to-type, autocorrect replacement) sends a
key.EditEvent with a Range that the editor ignored, causing the replaced
region to be duplicated. Add Logic.HandleReplaceRange which deletes the
rune range [start,end) and inserts text, converting rune indices to byte
offsets (string path: utf8.DecodeRuneInString; chunked path: leading-byte
scan). HandleKeyDown now routes key.EditEvent through it.

Also fixes two pre-existing ChunkedBuffer correctness bugs the tests
exposed:
- Delete mis-computed the per-chunk end using a shrinking 'remaining'
  instead of the absolute end, corrupting multi-chunk deletes.
- FullContent derived its chunk bound solely from fileLen, truncating
  in-memory chunks grown past the old bound by an insert.

Adds ime_range_test.go covering insert/replace/delete, unicode, chunked,
and swapped bounds. go test -race ./... green.

58725a5e6c Make state single-owner and stabilize race detector
Frame now carries view state (scale/focus/query) to the main goroutine,
which reads only the frame-receiver-stored snapshot. Renderer owns Gio
widget editors (registered by ID) and the draw scale. Autosave timer
sends a token to the logic goroutine instead of touching state;
Shutdown waits for the owner to exit before FlushAll.

Tests access state only through owner-side Inspect/WithState helpers
(harness + in-package). Fixed double-Harness.Run race in two e2e tests,
made TestWorkerPool_PriorityPreemption deterministic, and raised the
lazy-loading test timeout that was too short under -race.

go test -race ./... is now green.

7240b62a61 WIP baseline: Termux open-file bridge + word-wrap-aware viewport/scroll
- JNI: open_file_in_termux via ACTION_SEND intent (text/plain + file:// uri),
  global context ref kept from registerFragment
- impl_android.go: OpenFile(path) attaches current thread if needed
- NewLogic takes openfunc; State.open + ui.OpenFile now func(string)
- ChunkedBuffer.VisibleByteRange: word-wrap path using
  GlyphLayout.VisualLineStarts (+byteOffset, lineHeight, visual index param)
- GlyphLayout gains LineHeight; drawWrappedText records VisualLineStarts
- WordWrap default true; State.ByteOffset tracks first visible line
- types: VisualLineIndex
- scroll_fix_test.go (new)
- debug prints left in place (WIP; cleanup in later phase)

03fb63863c Fix test build after NewLogic signature change; add development plan draft
NewLogic now takes (FileSystem, path, openfunc); update the e2e harness
and editor tests accordingly. The harness uses a no-op openfunc, matching
impl_other.go (the real app's OpenFile is a platform bridge, no-op off
Android).

Also adds doc/development_plan.md (draft, with corrections note re: the
live repo state).

5a92ee9df3 Fix: restore previous directory on navigation failure
When directory navigation fails (e.g., permission denied on Android),
the browser now restores the previous path instead of staying in a
broken empty state. NavigateTo saves the current path to History, and
handleError restores it and re-builds the index for the previous
directory when a BuildIndexTask fails.

ce8dd82bb0 Remove duplicate browser state and fix sort mode toggle
- Remove currentBrowserState global and SetBrowserState from browser package
- Browser now receives sortHandler as a parameter instead of using global state
- Fix sort mode toggle: reload pages after clearing cache (was showing 'Loading...')
- Add String() methods to all UI element types for debugging
- Add e2e tests for sort mode functionality (5 tests)

The editor now owns all state; the browser is a pure function receiving
state and handlers through parameters.

8f185341b3 Implement per-pixel smooth scrolling for ListView
- Changed BrowserScrollOffset and ListView.ScrollOffset from int (row index)
  to ui.Dp (pixel offset) for smooth per-pixel scrolling
- Updated HandleBrowserScroll to use raw Dp delta instead of row-based
  scrolling with minimum ±1 row jumps
- Fixed search not triggering new frames by detecting query changes in
  main.go FrameEvent handler
- Fixed click misalignment by indexing RowFilenames with local index i
  instead of rowGlobalIndex
- Fixed bottom clamping using actual BrowserListHeight and corrected
  formula: maxScroll = totalRows * rowHeight - BrowserListHeight

23fdeabad4 Fix scroll clipping: ListView now clips scroll gestures to its region
- Add clippableElement interface for elements that need their own clip region
- ListView implements NeedsClip() so drawElement pushes a clip before Draw
- RegisterScroll no longer has its own clip; relies on element clip context
- Aligns with Gio's clip-based gesture registration model
- Fix scroll events firing outside the visible list area on browser page

Also:
- Update touch.md documentation to reflect clip-based interaction model
- Remove debug logging from ListView.Draw
- Remove TODO-click-fixes.md (all items resolved)

ad3049dd22 Browser page: scroll + click coexist via register order fix
- Added Page state (BrowserPage/EditorPage) and SortMode
- BrowserLayout with 30 static entries, sort toggle, search placeholder
- ListView rows clickable via per-row RegisterClick
- Scroll gesture registered at START of ListView.Draw (before clicks)
  so click gestures registered later are checked first during hit test
- Unique IDs for interactive elements: editor_text, browser_list, search_bar
- ListView.Interactions() filters out Scroll (registered in Draw, not registerInteraction)
- RegisterScroll added to Renderer, called from element Draw methods
- lastLineYChan frame loop fixed: only re-layout if value changed
- Back icon added, editor status bar shows active filename
