feat: hyphen-tag fix, contexts, table view, richer capture

[MattHandzel]

Works through the seven open Taskwarrior tasks tagged/projected task_nvim / taskwarrior_nvim.

Based on agent/centralize-taskwarrior-commands (PR #9), since it builds on the centralized command.read/command.mutate boundary.

Fixes

Hyphenated tag names (3b9dfcab — "TwFilter with +ais-research-taste fails to pull something up")

TW3's expression parser reads the hyphen in a bare +tag token as subtraction, which broke three separate paths:

path	before
:TwFilter +ais-research-taste	Cannot subtract from a Boolean value → silently empty buffer
task add … +foo-bar	tag landed inside the description
modify +foo-bar	exit 2, tag never applied

• shell_export now runs parsed args through normalize_tag_filters (the rewrite tw_export already used): +t → tags.has:t, -t → tags.hasnt:t, virtual tags verbatim.
• fields_to_args emits one tags:a,b replacement instead of per-tag +a/-b deltas. This also fixes partial tag removal on save, which the +t deltas never applied.
• New taskmd.tw_change_tag(uuid, tag, remove) merges a single-tag delta into the full set and replaces; used by the gm tag picker and :TwInbox.

Features

:TwContext (c12b4cbd — contexts like work/home)

Shows the active context, sets one by name, none clears it (idempotent — task context none exits 2 when already clear). TW 3.x applies contexts to reports but not to export, so the render path injects the context's read filter itself. Those tokens land in the rendered taskmd header, so the save path re-exports on the same effective filter — the e2e spec proves saving a context-narrowed buffer never touches the tasks the context hides. uuid:-targeted filters are exempt so opening one task can't come up empty.

:TwTable (6e9f911d — vit-like configurable table view)

One row per task, aligned columns, urgency-sorted (honors custom_urgency). <CR> opens the task under the cursor in an editable :Tw buffer, r refreshes, q closes; the view is read-only. Columns come from the new table_columns option — a field name or { field, label, width, align, format }. Omit width on one column and it absorbs the leftover window width; over-long cells ellipsize rather than overflow. Unrecognised field names are read straight off the exported task, so UDA columns need no wiring.

Richer capture window (14d722e8 — bigger, colored capture form)

• Lines below the first become annotations on the created task; <C-CR> opens one, <CR> still submits everything. capture_annotations = false opts out; capture_height sizes the form.
• The capture buffer now runs the task buffer's highlighter, so project:, priority:, due:, +tags and UDAs color as you type.
• Every remaining field:value token gets the new neutral TaskField group — a UDA never renders as plain description text — and the new field_colors option overrides any field by name (mirrors tag_colors). Clock times (09:30) and URL schemes are excluded.
• Also fixed: the <Esc> discard-confirm and its cursor restore only looked at line 1, so annotation text could be dropped without a prompt.

Add confirmation shows the task (978fb9d1)

added task didn't tell you whether the right thing went through — the notification now echoes the first ~40 chars of the parsed description, plus an annotation count when there is one.

Save popup / undo (fca82462)

confirm = false already skipped the popup and applied immediately; the summary notification is then the only checkpoint, so it now points at :TwUndo. Documented the confirm=false → notify → undo workflow.

0f0b9bbf (capture starts in insert mode) was already the behavior — it now has a regression test.

Verification

Every change is covered by specs driving the real task CLI (3.4.2) against an isolated TASKDATA, plus a unit spec for the pure tag-normalization logic.

tests/lua/bootstrap.sh          32 pass, 0 fail
tests/e2e/run.sh
  hyphen_tag_e2e_spec            6 pass
  capture_flow_e2e_spec          3 pass
  no_confirm_save_e2e_spec       2 pass
  context_e2e_spec               5 pass
  capture_rich_e2e_spec          5 pass
  table_view_e2e_spec            4 pass
  external_changes_spec          8 pass
  command_live_spec              5 pass
  e2e_spec                      94 pass, 1 fail (pre-existing)

Two pre-existing failures on this branch, both unrelated to these changes:

• e2e_spec "icons=true → NF glyph" — fails identically on a clean tree.
• capture_relative_dates_spec "due:today" — the assertion compares a UTC-now date prefix against a local-midnight timestamp, so it fails whenever the run happens between UTC midnight and local midnight.

Three of the e2e specs caught real bugs during development, all fixed here: the table view's flex column kept its content width when the fixed columns had eaten the budget (300-char rows), the generic field highlighter colored https:// as a field, and task context none exits 2 when no context is set.
