fix: space between review badge and PR/MR id in space labels

[ubuntudroid]

What

Space labels rendered the review-state glyph glued directly onto the sigil + id, e.g. ✅#123. This inserts a separating space so it reads ✅ #123.

Why

The glyph and the number ran together, which is hard to read. The space is added only when a glyph is present, so a plain id (no review badge) stays #123 with no stray leading space.

Change is in status_for_repo (poller-ctl.sh); the colored status dot was already spaced separately in poll_once, so this is the one spot where an icon touched the id.

Test

bash test.sh — all 106 tests pass; bash -n poller-ctl.sh clean.

Merge-order note — gci_strip_ci_prefix must match this new emit format

This PR changes only the emit side in status_for_repo (poller-ctl.sh): the review badge now renders <glyph> #123 (with a space) instead of <glyph>#123. It does not touch gci_strip_ci_prefix in lib.sh, which strips the badge glyph only in the glued form:

# lib.sh — strips glued only
"$e"'!'[0-9]*|"$e"'#'[0-9]*) rest="${rest#"$e"}"; break ;;

With the spaced emit, that pattern never matches, so any label carrying a surfaced review badge (approved/conflict/changes — plus merged once #6 lands) never strips, and the whole <glyph> #123 token re-accumulates one copy per poll (observed live: ✅ #123 ✅ #123 … growing every 30s). Plain ids with no badge are unaffected, which is why it only shows up on some workspaces.

On merge, update gci_strip_ci_prefix to strip both forms — add the spaced patterns next to the glued ones:

case "$rest" in
  "$e"'!'[0-9]*|"$e"'#'[0-9]*)   rest="${rest#"$e"}";  break ;;
  "$e"' !'[0-9]*|"$e"' #'[0-9]*) rest="${rest#"$e" }"; break ;;

Merge-order specifics:

• Independent of feat: make sidebar CI and review glyphs configurable via .env #5/feat: surface a merged badge when a branch's PR/MR has landed #6/fix: GitHub PRs never showed review glyphs, and CI dots misreported multi-workflow pushes #7 for triggering — the review-badge strip loop already exists on main, so fix: space between review badge and PR/MR id in space labels #8 alone introduces the accumulation.
• feat: make sidebar CI and review glyphs configurable via .env #5 (configurable-icons) and feat: surface a merged badge when a branch's PR/MR has landed #6 (merged-badge) both rewrite that same strip loop (configurable ${VAR-default} glyphs; added merged/🔀). Whichever of {fix: space between review badge and PR/MR id in space labels #8, feat: make sidebar CI and review glyphs configurable via .env #5, feat: surface a merged badge when a branch's PR/MR has landed #6} lands second/third must make sure the final glyph list in the loop carries the spaced patterns above.
• The round-trip test must exercise the spaced emit (<badge> #123), not the glued <badge>#123 — the original test used the glued form, which is exactly what hid this.
