v3.0.0

Added

• A line-coverage gate. bash bin/coverage.sh reports per-file coverage and fails under 90%,
  and CI enforces it on every pull request. It is a separate job from bin/check.sh, which stays
  fast. Coverage went from 78.5% to 90.1%, and closing that gap found and pinned several behaviours
  that were previously untested.

Fixed

• Concurrent panes no longer lose recency or archive state. Recording an open and archiving a
  saved review each read their file, changed it, and wrote the whole thing back as separate steps,
  so two panes acting at the same moment silently erased each other's change. Both are now a single
  locked transaction, as starring already was. Every durable file also gets a unique temporary
  sibling instead of one fixed name shared by every writer, which could leave a truncated file
  behind. Settings and zen chrome gain the same atomic replace while keeping their existing
  permissions.

Changed

• One prefix concept, everywhere. Which prefix a key wore used to depend on where it grew up:
  ctrl-s starred a command but sent a repo to an agent, alt-s sorted in Projects but opened
  Settings in the Central Menu, alt-u updated the plugin in Projects and used a Node version in
  the fnm manager, opening a workspace was alt-w here / ctrl-w there / bare w in Normal, and
  the changelog answered to three different letters. Now the prefix names the kind of work, and
  never the mode you are in:

  • ctrl-<key> acts on the selected row — open it, update it, remove it, copy it, send it,
    star it.
  • alt-<key> changes the view or the app — preview, sort, clone, changelog, settings, plugin
    update. It is also the heavier form of a ctrl verb on the same letter, such as Ports'
    ctrl-x TERM and alt-x KILL.
  • enter runs the row's primary action, with ctrl-enter / alt-enter as its variants.

  Every one of those chords now means the same thing in both Projects modes and on every
  picker. Normal mode adds bare aliases — t v o w p — always on the same letter as the
  chord they shorten, and motion keeps the idiom of its mode (readline while typing, Vim while
  navigating).

  The space leader is gone. Space can only be a leader in Normal — while typing it is a
  character you meant — so every verb living there was forced to change prefix with the mode, which
  was the inconsistency itself. space u / space x / space c / space l / space , /
  space U are now simply ctrl-r / ctrl-x / alt-l / alt-h / alt-, / alt-u, in both
  modes.

  What moved, in full: open in a tab ctrl-t → ctrl-e (Projects and AI Agents), because
  herdr consumes its prefix before a pane sees the key: a binding that is somebody's prefix never
  arrives at all, and ctrl-t is the usual prefix for anyone carrying tmux muscle memory while
  ctrl-b is herdr's own default. The open group avoids both, and nothing here may bind ctrl-b
  any more. Normal's bare alias follows the letter, so it is e. Then: star ctrl-b → ctrl-s; send to an agent ctrl-s → ctrl-a
  (Projects and the Git saved-review lists); open in a workspace alt-w → ctrl-w (Projects
  and AI Agents; Ports already used it); clone alt-enter → alt-l; changelog alt-c →
  alt-h; delete word ctrl-w → alt-backspace, which also revives it in the Ports picker
  where ctrl-w had silently killed it; and in Node Versions, alt-u use → ctrl-enter,
  alt-i install → alt-enter, alt-d default → ctrl-d, alt-x uninstall → ctrl-x.
  Commands, Zen, the Git menu and the Central Menu are unchanged.

  Old habits are a config block away — see Remapping in docs/keybindings.md. A Projects
  override now binds into both modes at once, so it cannot reintroduce the split, and the footer
  and ? cheatsheet render whatever you bind.

• The Central Menu and Node Versions can be rebound. They were the only two pickers with no
  [keys.*] table, so their keys were the ones nobody could move. [keys.menu] and [keys.fnm]
  now work like every other picker's.

• The empty Starred tab in Commands names the key you actually have. It printed a fixed
  ctrl-s even after [keys.commands] star was remapped, sending you to a key that no longer
  starred anything.

• A shift bit your terminal adds no longer loses the action. Projects weighed only ctrl and alt
  when resolving a key; every other picker compared the modifier bits exactly. So one press had two
  answers depending on which surface read it — shift-enter ran the selected row in Projects and
  did nothing in Commands, Ports, Agents, Zen, the Menu or Node Versions, and a chord arriving with
  a stray shift bit missed its ctrl- action outright. Both halves now decide the same way.

• A picker action that collides with a reserved chord is now caught at build time. The shared
  picker answers alt-,, alt-j, alt-k, tab and shift-tab before consulting a picker's own
  actions, so an action declared on one of those was silently swallowed — the way Ports' ctrl-w
  had quietly killed delete-word for that picker alone. Those chords are one table now, and a test
  every picker runs refuses an action that claims one, takes ctrl-c/ctrl-u, uses a bare letter
  (which would make that character untypeable), prints a cap that is not the key it listens for, or
  binds a shared action to a chord it does not carry elsewhere.

• A modified chord can no longer trigger a Git menu mnemonic. The menu matched a whether or
  not ctrl was held, so ctrl-a pressed one view too early would have started an all-files review
  — a minutes-long read — rather than doing nothing.

• Projects and the Commands, Ports, Agents and Menu pickers scroll and filter faster. Every
  visible and off-screen row was rebuilt from scratch on each frame; rows now reuse the text they
  already have. Star lookups, tab counts, the name ordering, and field filters no longer redo work
  per keystroke. A burst of wheel or held-key input is drawn once instead of once per event.

• Projects opens faster on machines with many repositories. Repositories with no linked
  worktrees are recognised from disk instead of costing a git process each, the two Herdr
  catalogue queries run at the same time, and a repository Inspector gathers its branch, status,
  last commit, and file tree concurrently.

• Pickers with nothing loading no longer wake twenty times a second. Commands, Agents, the
  Menu, and the Zen picker now idle until you press something, matching Projects and Git.

• Released binaries are built for speed rather than build time. Published archives now use a
  fully optimised profile; building from a linked checkout stays as quick as it was.
